The control bar display equipment can be a computer, a mobile phone, a projector, a tablet or an intelligent interactive tablet and the like.

Further, the control bar display device is provided with an operating system. The operating system may be a windows system and/or an Android system. Further, the control bar display device is provided with application software of an operating system, and is also provided with application software downloaded from a third-party device or a server. The specific type of the application software can be set according to actual conditions. In the embodiment, after the application software is set to be started, a corresponding display window is displayed in a screen of the control bar display equipment, so that a user can see an operation interface of the application software.

Typically, the application software has at least one control bar displayed in a display window. The control bar refers to an area for intensively displaying the controls in the display window, and the specific display position and the area size of the control bar are set according to the actual situation. Further, each control in the control bar corresponds to a function, and the control can be considered as a function entry. For example, the function corresponding to the control a is to insert a form, and it is determined that the function of inserting the form is started after the control is detected to be clicked. If the function corresponding to the control B is the function of expanding the sub-control, the hidden sub-control under the control is determined to be expanded after the control is detected to be clicked. In general, a control bar may be considered a menu bar and/or a tool bar. The menu bar is a control set arranged according to program function groups, and after a certain control of the menu bar is clicked, a menu item corresponding to the control can be displayed, namely, a corresponding sub-control is displayed, so that a specific function entry is provided. The toolbar is a control bar that displays a row of bitmap buttons, which can be understood as controls.

Further, in the embodiment, the length of the control bar in the target direction is set to be recorded as a first length, and the length of the display window where the control bar is located in the target direction is recorded as a second length, wherein the length is the total number of the required pixel points in the target direction in the display process. The target direction is generally the arrangement direction of the controls, which may be a horizontal direction or a vertical direction. Generally, the first length is equal to the second length, or the first length is less than the second length. Typically, the first length is calculated from the second length. For example, fig. 2 is a first schematic diagram of a partial interface of a display window, where a first length of the control bar 12 in the horizontal direction is equal to a second length of the display window 11 in the horizontal direction. For another example, fig. 3 is a second schematic diagram of a partial interface of a display window. At this time, a first length of the control bar 13 in the vertical direction is smaller than a second length of the display window 14 in the vertical direction, and the second length is calculated from the first length and the length of the menu bar 15.

In the embodiment, the application software is set to be the application software with the electronic whiteboard function, and the application software can be implemented through the electronic whiteboard function: writing, drawing, commenting, courseware making, displaying and playing. The electronic whiteboard function set in the embodiment has an element drawing and editing function. The elements are elements which can be displayed after a certain operation is input by a user, and have occupation spaces and editability. Based on the drawing and editing functions of the elements, the setting of the display window of the application software in the embodiment at least includes: a touch writing area and a touch management area. The touch writing area refers to an area where elements can be drawn, and the touch management area refers to an area where displayed content, a display window, and application software are controlled. For example, fig. 4 is a schematic view of a display window. Referring to fig. 4, the application software is courseware making software, and the display window 16 includes a touch writing area 161, a touch management area, and a control bar. Wherein, the touch management area includes: a first area 1621, a second area 1622. The first area 1621 is used to create a page, adjust the page arrangement order, and display page thumbnails. The second area 1622 is used to control the properties and animations of elements between and within pages. Further, the controls in the control bar corresponding to the touch writing area 161 are all related to the content of the input element, such as text, shape, multimedia, table, and the like. And the controls in the control bar corresponding to the touch control management area are all used for controlling elements or courseware formed by the elements. At this time, the setting control bar includes: the content input sub-control column and/or the content management sub-control column are described, and the control column includes the content input sub-control column and the content management sub-control column as an example. The content input sub-control bar refers to a sub-control bar integrating input controls related to input element contents. The content management child control bar refers to a child control bar integrating management controls related to control management. In general, in the target direction, each child control bar is the same length as the corresponding display area. For example, referring to fig. 4, the control column includes a content input sub-control column 1631 and a content management sub-control column 1632, the target direction is a horizontal direction, the length of the content input sub-control column 1631 is equal to the length of the touch writing area 161 in the target direction, and the length of the content management sub-control column 1632 is equal to the length of the touch management area in the target direction. Namely, the arrangement direction of the controls in the control bar is the horizontal direction, the content input sub-control bar is displayed in the same row with the touch writing area, and the content management sub-control bar is displayed in the same row with the touch management area. It can be understood that the arrangement direction of the controls in the control bar is a vertical direction, the content input sub-control bar is displayed in the same line as the touch writing area, and the content management sub-control bar is displayed in the same line as the touch management area. Since the touch management area includes two areas, the content management child control bar 1632 also includes two portions, and each portion corresponds to one portion of the touch management area.

Specifically, the embodiment describes a display method of the control bar by taking an example of adjusting a display size scene of the display window. Referring to fig. 1, the method for displaying a control bar of an electronic whiteboard specifically includes:

and S110, receiving the operation of adjusting the size of the frame.

Wherein the frame resizing operation acts on the target display window.

Specifically, the frame size adjustment operation is an operation for adjusting the display size of the display window. And recording the window selected by the frame size adjustment operation as a target display window. Optionally, when the control bar display device has a touch function, the user may send out a frame size adjustment operation in a manner of touching the control bar display device. At this time, the display screen of the control bar display device may be a capacitive screen, a resistive screen, or an electromagnetic screen. In the touch process, a user can send out a frame size adjustment operation through a finger or a touch pen. Optionally, the user may send out the operation of adjusting the size of the bezel in a key manner through an external device connected to the control bar display device. The external device includes but is not limited to a mouse and/or a keyboard, and the connection mode of the external device and the control bar display device includes but is not limited to a wireless connection and/or a wired connection.

Further, the specific triggering mode of the frame size adjustment operation can be set according to the actual situation. For example, when it is detected that a drag operation is received at a position of a frame of a certain display window, it is determined that a frame size adjustment operation is received. If the sliding operation in the opposite direction is detected to be received at the internal position of the display window, the frame size adjustment operation is determined to be received.

And S120, adjusting the target display window to a target size.

And the target size is determined according to the frame size adjustment operation.

Specifically, the target size is a display size to which the user desires to adjust the target display window. The display size can be represented by the number of the pixel points. For example, the display size may be represented by the total number of pixels in the target display window, for example, the target display window needs 1024 pixels in the horizontal direction and 768 pixels in the vertical direction, and then the display size of the target display window is 1024 × 768. Optionally, the display size may be determined only by the pixel point in the target direction where the control bar is located. For example, the target direction is the horizontal direction, the target display window needs 1024 pixels in the horizontal direction, and then the display size of the target display window is 1024.

Further, the target size is determined according to the frame size adjustment operation. Specifically, the target size is determined according to the end position of the frame size adjustment operation. For example, it is determined that a certain point on a vertical frame of the target display window is horizontally dragged to a certain position according to the frame size adjustment operation, and then, after the position is taken as a new display position of the point, the scaling of the target display window in the horizontal direction can be determined, and further, the target size is determined. For another example, it is determined that a vertex on the frame of the target display window is dragged to a certain position according to the frame size adjustment operation, and then the position is used as a new display position of the vertex, so that the scaling of the target display window can be determined, and the target size is obtained. Optionally, the target size is determined according to the moving amplitude of the frame size adjustment operation. For example, if it is determined that a frame size adjustment operation is received in the target display window and the frame size adjustment operation moves 20 pixels, a scaling corresponding to 20 pixels is determined, and the target size is obtained.

S130, displaying the control bar according to the set display style, so that the control in the control bar meets the preset calling requirement.

The control bar is positioned in the target display window and comprises a content input sub-control bar and/or a content management sub-control bar. The set display style comprises at least one of the number of controls, display patterns of the controls, arrangement sequence among the controls, arrangement direction of the controls and display width of the controls, and is determined according to the target size. In an embodiment, the settings control column includes a content input child control column and a content management child control column.

For example, the preset calling requirement refers to a calling requirement of a user for a control under a target size. The content and setting of the default call request are not limited according to the embodiment. For example, in combination with historical use data of the user, it is determined that the user uses more functions in each target size, and then a preset call requirement is set to meet the call of the user to the functions.

Specifically, the set display style includes at least one of the number of controls, a display pattern of the controls, an arrangement order between the controls, an arrangement direction of the controls, and a display width of the controls, where the number of controls refers to the number of controls that can be displayed in a current control bar, and the display width refers to the total number of pixel points in a target direction of a display area allocated for the controls. Optionally, display styles corresponding to different display sizes are preset. And after the target display window is adjusted to the target size, acquiring a display style corresponding to the target size as a set display style, and further displaying the control in the control bar according to the set display style. Generally, when the display style of the control bar is changed, the controls in the control bar are set to be complete display patterns, and the situation that a certain control is only partially displayed cannot occur.

Further, after changing the display size of the target display window, if the difference between the current target size and the display size before changing is small, for example, the display size is changed from 1010 to 1015, the display styles of the control bar may be the same, that is, when the display size adjustment range of the target display window is too small, the display styles corresponding to the control bar may be the same. Accordingly, different size ranges are set to be divided in advance based on the set size, and each size range corresponds to a different display style. When the target display window is displayed on the screens with different resolutions, the proportional relation between the set size and the screen size can be determined, and further, each size range under the screen size is determined according to the proportional relation. Further, after the target display window is adjusted to the target size, the size range corresponding to the target size is determined, and then the set display style corresponding to the size range is determined, so that the control bar is displayed according to the set display style.

Optionally, the display styles corresponding to different target sizes can be set according to actual conditions, and only the preset calling requirements need to be met. For example, when the target size is full screen or close to full screen, the display style is set to display all the controls in the control bar, and the controls are preset controls which need to be displayed in the display bar. When the target size is half screen or close to half screen, the display style is set to display the set number of controls in the control bar. Compared with full-screen display, the number of controls in the control bar is reduced when half-screen display is performed. At this time, in order to enable the user to call out the control not displayed in the control bar, a first replacement button may be optionally added to the control bar, so that when the first replacement button is selected by the user, the control in the current control bar is replaced with the control not displayed. It is clear that, in addition to the above-mentioned way of adapting to different target sizes by changing the number of controls in the control bar, different target sizes can be adapted by adjusting the display pattern, the arrangement direction, and the display width of the controls. For example, when the target size falls within a relatively large size range, such as full screen, the display pattern of the control within the control bar may include an icon and a corresponding control name. When the target size belongs to a relatively small size range, such as a half screen or a size close to a set minimum size, the display pattern of the control may only include icons, thereby reducing the number of pixels required for displaying the control. For another example, compared with full-screen display, when the target size belongs to the half-screen size range, the display width occupied by each control in the control bar may be appropriately reduced, so as to change the length of the control bar by changing the display width. It should be noted that, in combination with the actual situations of the control bar display device and the target display window, one or more combinations of the above manners may be selected to determine the display contents corresponding to different target sizes. Meanwhile, other ways of changing the display content of the control bar are also applicable to the embodiment.

Furthermore, because the control bar comprises the content input sub-control bar and the content management sub-control bar, the display styles of the content input sub-control bar and the content management sub-control bar are respectively set when the target sizes are different, and then the content input sub-control bar and the content management sub-control bar are respectively adjusted according to the corresponding display styles.

In practical application, after the target size is determined, the set display style corresponding to the target size may be determined first, and then the size of the target display window and the control bar are adjusted synchronously. It should be noted that, no matter whether the size of the target display window and the control bar are adjusted synchronously or not, from the viewing perspective of the user, the size adjustment process of the target display window and the adjustment process of the control bar are almost synchronous, and the user cannot obviously distinguish the execution sequence.

The technical scheme provided by the embodiment, through receiving the frame size adjustment operation acting on the target display window, adjust the target display window to the target size according to the frame size adjustment operation, simultaneously, the technical scheme of displaying the control bar according to the set display style corresponding to the target size can be solved, when the display size of the display window changes, the technical problem that the user cannot call the control due to the fact that the display position and the display size of each control in the control bar are fixed is solved, the display style in the control bar can be changed synchronously along with the change of the target size, meanwhile, the control displayed in the control bar is convenient for the user to call, and the use experience of the user is improved.

Example two

Fig. 5 is a flowchart of a control bar display method of an electronic whiteboard according to a second embodiment of the present invention. The method for displaying the control bar of the electronic whiteboard according to the embodiment is embodied on the basis of the above embodiment. Specifically, referring to fig. 5, the control bar display method specifically includes:

s201, receiving frame size adjustment operation.

Wherein the frame resizing operation acts on the target display window.

S202, adjusting the target display window to a target size. When the target size belongs to the third size range, S203 is performed; when the target size belongs to the fifth size range, S204 is performed; when the target size belongs to the fourth size range, S205 is performed; when the target size belongs to the sixth size range, S210 is performed.

Specifically, the display size of the target display window is divided into different size ranges in advance. In the embodiment, the division into 4 size ranges is taken as an example. The size in the third size range is the largest, the size in the fifth size range is smaller than the size in the third size range and larger than the size in the fourth size range, and the size in the fourth size range is smaller than the size in the fifth size range and larger than the size in the sixth size range. For example, a first length of the control bar in the horizontal direction is set to be equal to a second length of the target display window in the horizontal direction, and the target size is the number of pixels of the target display window in the horizontal direction. At this time, the third size range is set to be more than 1600, the fifth size range is set to be 1200-1600, the fourth size range is set to be 600-1200, and the sixth size range is set to be less than 600.

Further, a display style corresponding to each size range is preset. When the target display window is adjusted to the target size, the size range to which the target size belongs can be determined, the display style corresponding to the size range is further determined as the set display style, and the control bar is displayed according to the set display style.

It should be noted that the above-mentioned four size ranges are only an exemplary setting, wherein each size range corresponds to a different display rule. In practical application, more size ranges or fewer size ranges can be set according to practical situations, and meanwhile, the combined application or repeated application of each display rule can be set. Optionally, a plurality of sub-ranges may be set for a certain size range, and different display rules may be set for each sub-range, so as to enrich the changing content of the control bar.

And S203, displaying all the controls in the control bar, wherein each control corresponds to the first display width.

And when the target size corresponds to the third size range, setting all the controls displayed in the control bar, namely, setting the number of the controls to be equal to the total number of the controls. The control is a preset control which needs to be displayed in the control bar. Optionally, the controls may be set by the control bar display device and/or set by the user. In general, the total number of controls is less than or equal to the maximum number of control bar display controls. However, if the total number of controls is greater than the maximum number, the thumbnail symbol may be displayed and the control not displayed may pop up when the user clicks the thumbnail symbol, or a first alternative button may be displayed and the control in the control bar may be replaced when the user clicks the first alternative button.

Illustratively, the display width of each control is a first display width corresponding to the control. Each control can have a plurality of different display widths, and the display widths are different in size and can be set according to actual conditions. Wherein the first display width is a maximum width of the plurality of different display widths. In general, the first display widths of the different controls may be the same or different. It may be determined that when the target size is within the third size range, the number of controls is the largest, and each control corresponds to its largest display width.

It should be noted that the maximum value of the third size range may be the size of the display screen, and the minimum value may be the sum of the first display widths of the controls.

Further, the setting of displaying all the controls in the control bar includes: and displaying all input controls in the content input sub-control column, and displaying all management controls in the content management sub-control column.

Specifically, the control displayed in the content input child control column is set to be recorded as an input control, and the control displayed in the content management child control column is recorded as a management control. The input control refers to a control related to the content of the input element, and the management control refers to a control related to content management. At this time, the control includes an input control and a management control. Further, when the target size is within the third size range, all of the input controls and the management controls are displayed.

And S204, displaying all the controls in the control bar, wherein each control corresponds to a second display width, and the second display width is smaller than the first display width.

Specifically, the fifth size range may be considered to be a next largest size range that is only smaller than the third size range. Generally, the target size is within the fifth size range, and the control bar can still display the maximum number of target controls, i.e., the maximum number of controls. However, the display width of each control needs to be reduced to ensure that each control is completely displayed in the control bar. At this time, setting a second display width corresponding to each control in the control column. Wherein the second display width is smaller than the first display width. Likewise, the second display widths of the controls may be the same or different. It should be noted that the display patterns of the same control corresponding to the first display width and the second display width are the same. Optionally, when the same control is in the first display width and the second display width, the number of pixels occupied by the display pattern is the same, that is, from the user perspective, the distance between the controls is different in the first display width compared with the distance between the controls in the second display width, and the display pattern is not changed. Optionally, when the same control is in the first display width and the second display width, the number of pixels occupied by the display pattern is different, that is, from the user perspective, the display pattern of the control in the second display width is reduced compared to the first display width. It will be appreciated that the maximum value of the fifth size range may be determined from the third size range and the minimum value may be the sum of the second display widths of the controls.

In practical application, when the target size is within the fifth size range, part of the controls may correspond to the second display width, and the rest of the controls may correspond to the first display width, where part of the controls may be set according to actual conditions. For example, each management control in the content management sub-control column corresponds to a first display width, and each input control in the content input sub-control column corresponds to a second display width.

S205, displaying a first replacement button and a first control in the control bar, wherein the first control is a non-hidden control in all the controls.

And the number of the controls of the first control is determined according to the current display width and the target size of each non-hidden control.

At this time, the current display width of each control is the second display width. In practical application, the fifth size range may also be set to be cancelled, that is, the second size range may be a second largest size range, and at this time, the current display width of each control is the first display width.

For example, when the target size is within the fourth size range, all the controls cannot be displayed in the control bar, and therefore, only a part of the controls are displayed in the control bar, and the rest of the controls are hidden. In the embodiment, a part of the displayed controls is marked as a first control, wherein the number of the controls of the first control is determined according to the current display width and the target size of the controls. For example, the number of the controls that can be displayed in the control bar is determined according to the target size and the current display width of the controls, and at this time, when the target size changes within the fourth size range, the number of the controls displayed in the control bar may change along with the change of the target size. For another example, the number of the controls that can be displayed in the control bar is determined according to the minimum value of the fourth size range and the current display width of the controls, and at this time, when the target size changes within the fourth size range, the number of the controls displayed in the control bar does not change.

Further, the first control may be considered a non-hidden control. The non-hidden controls can be understood as controls which are kept to be displayed when the control bar cannot display all the controls. Specifically, the determination mode of the non-hidden control can be determined according to actual conditions. For example, the non-hidden controls may be determined according to the order in which the controls are arranged in the control bar. Assuming that the number of controls of the first control is 5, the non-hidden control is the control with the top 5 in the sequence of all controls. As another example, the non-hidden controls may be determined based on the display priority of each control. Assuming that the number of controls of the first control is 5, the non-hidden control is the first 5 controls with the highest display priority among all the controls. It is understood that the non-hidden control may be only an input control, only a management control, or both an input control and a management control.

Specifically, since the control bar only displays the non-hidden control, in order to facilitate the user to call out the hidden control, the embodiment sets to display the first control, and synchronously displays the first replacement button. The specific display position and the display form of the first replacement button can be set according to the actual situation. For example, a first alternative button is displayed at the end of the first control arrangement in the control bar to prompt the user to bring up the hidden control through the button. For another example, when the hidden control is only an input control, a first alternate button may be displayed in the content input sub-control bar; when the hidden control manages only controls, a first replacement button may be displayed in the content management sub-control bar; when the hidden control includes both an input control and a management control, the first replacement button may be displayed in the content management sub-control column and the content input sub-control column at the same time, or selectively displayed in any one of the sub-control columns according to actual conditions.

Optionally, when the first control is displayed, the display pattern of the control with the largest display width in the first control may be replaced to reduce the display width of the control, and further expand the size range of the fourth size range. Wherein, the replacing display pattern can be a reduced pattern, a reduced element in the pattern, etc.

Optionally, considering that the first control may be an input control and/or a management control, in this embodiment, the fourth size range includes a first sub-range and a second sub-range, and the size in the first sub-range is larger than the size in the second sub-range. The target size is within the first sub-range, S205 includes: and displaying a first replacement button and a part of input controls in the content input sub-control column, and displaying all management controls in the content management sub-control column. The target size is within the second sub-range, S205 includes: displaying the first replacement button and the partial input control in the content input sub-control bar, and canceling the display of the content management sub-control bar.

Specifically, the first sub-range is larger than the second sub-range, when the target size is in the first sub-range, it is determined that a part of the control needs to be hidden, at this time, a hidden part input control is set, and a first replacement button is displayed in the content input sub-control bar. In the content management child control column, all management controls are set to be displayed. At this time, the first control includes all the management controls and part of the input controls. The determination rule of the displayed part of the input controls is not limited, for example, the number of controls displaying the input controls is set, and the input controls with the front arrangement order in the content input sub-control bar are kept to be displayed according to the number of the controls. Further, when the target size is reduced to the second sub-range, only hiding part of the input control cannot guarantee that the target display window is reduced continuously, and at this time, setting to cancel the display content management sub-control, that is, the first control only includes part of the input control. At this time, since the management control has been already displayed, the user cannot call it in the control bar.

Further, in practical applications, the content management sub-control bar may be divided into a plurality of portions, for example, in fig. 4, the content management sub-control bar 1632 includes a portion corresponding to the first area 1621 and another portion corresponding to the second area 1622. Therefore, when the display of the content management child control bar is cancelled, the rule for canceling the display of the content management child control bar can be determined.

Accordingly, in an embodiment, the content management child control bar includes: a content switching sub-control bar and a content storage sub-control bar; at this time, the cancel display content management child control bar includes: and canceling the display of the content switching sub-control bar and/or canceling the display of the content storage sub-control bar.

The management control displayed in the content switching sub-control column may be recorded as a switching control, and the switching control is used for managing attribute information (such as page layout and page backlight) of a page where the elements are located, and animation rules of the page and each element inside the page during switching. The management control displayed in the content storage child control bar can be recorded as a storage control, and the storage control is used for managing functions of cloud uploading, cloud downloading, synchronization and the like of the application software recognizable files. That is, the management controls may include: a switching control and a storage control. Specifically, the control area corresponding to the content switching sub-control bar is used for displaying a specific function implementation entry corresponding to the switching control. The control area corresponding to the content storage sub-control bar is used for displaying the thumbnail of the page and the arrangement sequence between the pages, and it should be noted that in practical application, the specific content of the control area corresponding to the content switching sub-control bar and the content storage sub-control bar can be set according to practical situations.

Further, when the display content management child control bar is cancelled, the switching child control bar of the cancellation display content and/or the storage child control bar of the cancellation display content can be set according to actual conditions. For example, it is set that only the switching of the child control bar to the display content is canceled, and all the storage controls are displayed in the content storage child control bar. And if so, setting to cancel the switching of the display content to the child control bar and then cancel the storage of the display content to the child control bar.

Optionally, the setting the second sub-range in the embodiment includes: the size in the first grandchild range is larger than that in the second grandchild range; the target size is in the first grandchild range, and the cancel display content management child control bar comprises: canceling the display content switching sub-control bar, and displaying all storage controls in the content storage sub-control bar, wherein the storage controls belong to the management controls; the target size is in the second grandchild range, and the cancel display content management child control bar comprises: and canceling the display content switching sub-control bar and the content storage sub-control bar.

Specifically, the management control includes a storage control and a switching control. The specific size embodiments of the first grandchild range and the second grandchild range are not set. And when the target size is in the first grandchild range, setting a cancel display content switching child control bar. That is, there is no switching control in the current control column, and all storage controls are displayed in the content storage sub-control column. And when the size range is reduced to a second grandchild range, canceling the display content storage child control bar on the basis of canceling the display content switching child control bar. At this time, there is no management control in the control bar. By gradually canceling the display of the management control, more control bar display schemes can be provided when the user adjusts the target size.

It should be noted that, in the embodiment, the priority of the storage control is set to be greater than the priority of the switching control. In practical application, the priority of the switching control may be set to be greater than the priority of the storage control. Namely, when the target size is in the first grandchild range, the content storage cancellation child control bar is set, and all switching controls are displayed in the content switching child control bar. And when the target size is in the second grandchild range, setting a cancel display content storage child control bar and a content switching child control bar.

S206, receiving a first click operation.

Wherein the first clicking operation acts on the first replacement button.

Illustratively, the first clicking operation is an operation performed by the user to click a first alternate button. Generally, when the control bar display device has a touch function, the user may issue a first click operation by touching a first alternative button. In addition, the user can click the first replacement button in a keying mode through an external device connected with the control bar display device to send out the first click operation. Further, after the control bar display device determines that the first replacement button is clicked, it is determined that the first click operation is received.

And S207, replacing the set control in the control bar with a second control, and displaying a second replacement button.

The second control is a hidden control in all the controls, and the set control is a part of non-hidden controls or all non-hidden controls in the first control. Preferably, when the first replacement button is located in the content input sub-control bar, the hidden control refers to a hidden partial input control.

Specifically, because only a part of the controls can be displayed in the control bar, when the hidden controls are displayed in the control bar, part or all of the non-hidden controls in the control bar need to be cancelled and the hidden controls are displayed in the display area left after cancellation of the display. From a user perspective, it may also be understood to replace some or all of the first control with a second control.

Further, the hidden control displayed in the control bar is marked as a second control. Generally, the number of controls of the second control is equal to the number of controls of the set control.

Specifically, the setting control may be a part of the non-hidden controls or all of the non-hidden controls in the first control, and the specific selection mode may be determined according to the control replacement mode and/or the number of hidden controls. Optionally, the replaceable controls are set in the first control, at this time, the set controls are only selected from the replaceable controls, and for the non-replaceable controls in the first control, the controls are always displayed in the control bar. Wherein, the replaceable control can be set according to actual conditions. For example, a portion of the input controls are displayed in the current control bar and all of the management controls are displayed. At this time, the management control is an irreplaceable control, that is, the display content of the content management sub-control column is not changed, and meanwhile, part of the input controls are replaceable controls, that is, the display content in the content input sub-control column can be changed. In the embodiment, the setting control is taken as an input control in the content input sub-control column as an example, and at this time, the setting control refers to a non-hidden partial input control. Hidden controls refer to hidden partial input controls.

In an embodiment, when the setting control is a part of the non-hidden controls in the first control, the changing the setting control in the control bar to the second control specifically includes: canceling the display setting control; and moving the non-hidden controls reserved in the first control to the display position of the set control according to the arrangement sequence, and supplementing a second control at the blank position of the control bar.

At this time, setting the control as a part of the non-hidden control in the first control means: and setting the control as part of the currently displayed input controls.

For example, fig. 6 is a first schematic view of a partial interface of a target display window. Referring to fig. 6, a content input sub-control field 2101 and a content storage sub-control field 2102 are included in the control fields. At this time, a part of the input controls and the first replacement button 22 are displayed in the content input sub-control field 2101, and all the storage controls are displayed in the content storage sub-control field 2102. Wherein the replaceable control in the first control is a control in the content input child control field 2101. Optionally, the setting alternative mode is a moving mode, the first control of the content input sub-control field 2101 is moved out of the content input sub-control field 2101, and the controls behind the first control are sequentially moved forward by a position according to the arrangement order, at this time, a hidden control can be displayed at the position left behind the content input sub-control field 2101, that is, the number of controls of the setting control is 1, and the setting control and the hidden control are both input controls. For example, the setting control 21011 in fig. 6 is moved out of the control bar, the controls behind the setting control 21011 are sequentially moved forward by one position, and a hidden input control 21012 is added at the position behind the content input sub-control bar 2101, at this time, the control bar after replacement refers to fig. 7, and fig. 7 is a second schematic diagram of a local interface of a target display window.

Optionally, the total number of hidden controls is counted, and if the total number is smaller than the number of controls of the replaceable controls, the number of controls of the controls is set to be equal to the total number. That is, starting with one of the replaceable controls, the total number of controls is dismissed and the remaining controls are advanced to display all hidden controls at the vacated position behind the control bar. For example, the setting control and the hidden control are both input controls, and the number of the hidden controls is 3. At this time, referring to fig. 6, the display interface specifically takes the first 3 moving controls in the content input sub-control field 2101 in fig. 6 as setting controls, and moves out of the content input sub-control field 2101. Then, the remaining input controls in the content input child control field 2101 are moved forward to supplement 3 hidden input controls in the content input child control field 2101, at this time, the replaced control field refers to fig. 8, and fig. 8 is a third schematic diagram of a local interface of the target display window.

When the control is set to be all the non-hidden controls in the first control, the display of the first control can be directly cancelled, and the hidden control is displayed in the control bar. In the embodiment, the setting control and the hidden control are both input controls as an example for description. At this time, the number of the controls of the hidden controls does not need to be considered, and the corresponding hidden controls are supplemented after all the replaceable controls are cancelled and displayed. For example, referring to fig. 6, the display interface replaces all the mobile controls in the content input sub-control field 2101 in fig. 6 with second controls, at this time, the replaced control field refers to fig. 9, and fig. 9 is a fourth schematic view of a partial interface of the target display window.

Optionally, after the hidden control is displayed, the corresponding replaced non-hidden control may also be considered to be hidden in the control bar. At this time, there may be a case where the non-hidden control needs to be displayed again, and then the non-hidden control displayed again is a control in the currently existing child control bar, and for the child control bar which is not displayed, the control bar can be re-displayed only in a manner of changing the target size. For example, there is a content input child control bar in the current control bar, while the content management child control bar is dismissed. Then, displaying the non-hidden control again without changing the target size means displaying the non-hidden mobile control in the content input sub-control bar. Accordingly, as a preferable mode in the embodiment, when the setting control in the control bar is replaced with the second control, the second replacement button may be displayed at the same time. The specific display position and the display form of the second replacement button can be set according to the actual situation. For example, a second alternative button is displayed at the front of the arrangement of alternative controls in the control bar. As another example, the second replacement button is displayed below the first replacement button, and so on. Generally, the second alternate button and the first alternate button are displayed in the same child control bar. For example, when the first replacement button is set to be displayed in the content input sub-control bar, the second replacement button is also set to be displayed in the content input sub-control bar.

And S208, receiving a second click operation.

Wherein the second clicking operation acts on the second replacement button.

Illustratively, the second clicking operation is an operation performed by the user to click a second replacement button. Generally, when the control bar display device has a touch function, the user may issue a second click operation by touching a second alternative button. In addition, the user can click the second replacement button in a keying mode through the external device connected with the control bar display device to send out a second click operation. Further, after the control bar display device determines that the second replacement button is clicked, it is determined that a second click operation is received.

And S209, replacing the second control in the control bar with a setting control.

Specifically, the process of replacing the second control in the control bar with the setting control can be understood as an inverse process of replacing the setting control with the second control, and specific contents thereof are not described herein again. For example, as shown in fig. 8, when it is determined that the second replacement button 23 receives the second click operation, the reverse process of replacing the setting control with the third control is performed, that is, the display interface is restored to the interface shown in fig. 6.

Optionally, if the hidden control at the end of the arrangement order is already displayed, it is determined that all the hidden controls have already been displayed in the control bar, and at this time, when the first replacement button receives the first click operation again, no operation is executed. Thus, in this case, the first alternative button may be dismissed from display and displayed again when the endmost hidden control is again hidden. Wherein, the endmost hidden control refers to the control which is displayed in the corresponding child control bar last. For example, the current partial display interface of the target display window is as shown in FIGS. 8 and 9, where the endmost hidden control refers to the "discipline tool" at the end of the ranking order in the content input sub-control field 2101. At this time, since the endmost hidden control is already displayed in the control bar 21, only the second replacement button 23 is displayed in the control bar 21.

It should be noted that, in practical applications, the second replacement button may not be displayed, but the function of the second replacement button may be integrated with the first replacement button. For example, when it is determined that the first replacement button receives the click operation, the setting control is replaced with the second control, and after the hidden control at the end is displayed, if it is determined that the first replacement button receives the click operation again, the second control is replaced with the setting control.

S210, replacing the display patterns of the currently displayed controls in the control bar to reduce the display width of the currently displayed controls.

Specifically, when the target size is within the sixth size range, the number of the controls displayed in the control bar has reached the preset minimum number, and at this time, the display width of each control can be reduced by using a smaller display pattern in a manner of replacing the display pattern of the controls in the control bar, so that when the minimum number of target controls are displayed in the control bar, the display size of the target display window can be continuously reduced.

The specific mode of replacing the display pattern of each control currently displayed can be set according to the actual situation. For example, before replacement, the display pattern of each control in the control column is composed of an icon and a Chinese name, and only the icon or the Chinese name can be reserved during replacement to reduce the display width of the control. For another example, the display pattern of the replacement control is specifically a display pattern of a reduced control, so as to reduce the display width of the control.

The embodiment specifically sets the step as follows: and keeping the icons of the currently displayed controls, and deleting the Chinese names corresponding to the currently displayed controls.

Specifically, the display pattern of the control includes an icon and a chinese name. The specific arrangement mode of the icons and the Chinese names can be set according to the actual situation. For example, a Chinese name is displayed below the icon. In general, the display width of the chinese name is larger than the display width of the icon. When the target size is in the fourth size range, only the icon of the control is displayed, so that the display width of the control can be reduced.

It should be noted that, within the sixth size range, the display patterns of all the controls are replaced, regardless of whether the display patterns are displayed in the control bar, so as to ensure that when the first replacement button or the second replacement button receives a click operation, the display pattern of the hidden control is still the replaced display pattern.

Optionally, when the display pattern is replaced, only the display pattern in part of the child control bar may be replaced. For example, if the content input sub-control column and the content storage sub-control column currently exist are set, only the display pattern of each input control in the content input sub-control column may be replaced, and the display pattern of each storage control in the content storage sub-control column may be maintained.

In practical application, size ranges different from those in the embodiment may be set, and the setting display style of the control bar corresponding to the different size ranges may be set by itself. For example, when the target size is in a certain size range, part of the controls and the first replacement button are displayed in the control bar, when the target size is changed to another smaller size range, a certain number of the controls are cancelled and all the rest of the controls are displayed in the control bar, and when the target size is changed to the smallest size range, part of the controls are selected from all the rest of the controls to be displayed in the control bar, and the first replacement button is synchronously displayed.

For example, fig. 10 is a fifth schematic view of a partial interface of a target display window, where at this time, the target size corresponds to a third size range, and all controls are correspondingly displayed in the control bar. At this time, the control fields include a content input child control field 2101, a content storage child control field 2102, and a content switching child control field 2103, and all corresponding controls are displayed in each child control field. When the target size of the target display window continues to change and reaches the minimum value of the third size range, the partial interface schematic diagram of the target display window changes from fig. 10 to fig. 11. Fig. 11 is a sixth schematic view of a partial interface of the target display window, and as can be seen from fig. 11, if the target size continues to be reduced, the current display content cannot be continuously displayed in the control bar 21. Then the target size enters the fifth size range as the target size of the target display window continues to shrink, at which point the partial interface schematic of the target display window is shown in fig. 12. Referring to fig. 12, the control column 21 continues to display all the controls, except that the display width of each control is significantly reduced compared to the display content in fig. 11 to create a blank area in the control column 21. At this time, the display widths of the controls in the sub-control columns are set to be reduced. As the target size continues to shrink, the blank area may be shrunk. Optionally, in order to enlarge the blank area, in this example, the display pattern of the target control 24 with the largest display width is changed, i.e., the chinese name of the target control 24 is cancelled, so as to reduce the display width of the target control 24. Further, when the target size is reduced to the minimum value of the fifth size range, the partial interface schematic diagram of the target display window is changed from fig. 12 to fig. 13. Fig. 13 is an eighth schematic view of a partial interface of the target display window, and as can be seen from fig. 13, if the target size continues to be reduced, the current display content cannot be continuously displayed in the control bar. Then the target size enters the first sub-range of the fourth size range as the target size of the target display window continues to shrink. At this time, a partial interface diagram of the target display window is shown in fig. 14. FIG. 14 is a ninth illustration of a partial interface of a target display window. Referring to fig. 14, a first alternative button 22 and a first control are displayed in the control bar 21. Where a first alternative button 22 is displayed in the content input sub-control field 2101. Meanwhile, the hidden control is a partial input control. The number of controls of the first control is less than the total number of all controls. Further, as the target size continues to shrink, the number of input controls in the content input sub-control field 2101 may continue to decrease. When the target size is reduced to the minimum value of the first sub-range, the partial interface schematic diagram of the target display window is changed from fig. 14 to fig. 15. Fig. 15 is a tenth schematic diagram of a partial interface of the target display window, and as can be seen from fig. 15, if the target size continues to be reduced, the current display content cannot be continuously displayed in the control bar. Then the target size enters the second sub-size range as the target size of the target display window continues to shrink. At this time, the target size is set to enter the second sub-size range. A partial interface schematic of the target display window is shown in fig. 16. FIG. 16 is an eleventh schematic diagram of a partial interface of a target display window. Referring to fig. 16, in contrast to fig. 15, the content switching sub-control field 2103 in the control field is not displayed. It should be noted that, after the content switching sub-control field 2103 is canceled from being displayed, the size of the content input sub-control field 2101 is significantly increased, so that as many input controls as possible can be displayed in the content input sub-control field 2101. In fig. 16, the content input sub-control field 2101 may display all input controls, and therefore, the first replacement button may be cancelled in the content input sub-control field 2101, and at this time, all controls except the toggle control may be displayed in the determination control field 21. Further, as the target size continues to decrease within the second sub-range, the partial interface view of the target display window changes from FIG. 16 to FIG. 17. At this time, since all the input controls cannot be displayed in the content input sub-control field 2101, a part of the input controls is hidden in the content input sub-control field 2101, and the first substitute button 22 is displayed. When the target control continues to shrink to the minimum size of the second sub-range, the partial interface schematic diagram of the target display window changes from fig. 17 to fig. 18. Fig. 18 is a thirteenth schematic diagram of the partial interface of the target display window, and as can be seen from fig. 18, if the target size continues to be reduced, the current display content cannot be continuously displayed in the control bar. Then the target size enters the sixth size range as the target size of the target display window continues to shrink, at which point the partial interface schematic of the target display window is shown in fig. 19. Referring to fig. 19, the display patterns of the respective controls in the content input sub-control field 2101 and the content storage sub-control field 2102 are replaced, and at this time, the display patterns of the controls only retain icons, and the chinese names are cancelled, so that the display width of the target control is reduced. Generally, the sixth size range is the minimum size range of the target display window, and the control bar cannot be reduced after reaching the minimum value of the sixth size range. For example, fig. 20 is a fifteenth schematic view of a partial interface of a target display window, where the target size reaches the minimum value of the fourth size range, and the target size cannot be reduced any more.

The technical solution provided by this embodiment is to receive a frame size adjustment operation applied to a target display window, adjust the target display window to a target size according to the frame size adjustment operation, determine a size range to which the target size belongs, and display a corresponding control in a control bar according to the size range, so as to solve the technical problem that when the display size of the display window changes, the display position and the display size of each control in an internal control bar are fixed, which results in that a user cannot invoke the control, to realize that the display style in the control bar changes synchronously with the change of the target size, and at the same time, when the control bar cannot display all the controls, by setting a first replacement button and a second replacement button, the hiding and displaying of the controls can be realized, and the display styles of a content input control bar and a content management control bar under different target sizes can be respectively formulated, and the child control columns with different functions can be adjusted differently, so that the user can call the control conveniently. In addition, the display contents corresponding to different display sizes are set, so that the corresponding display contents can be directly called when the display sizes are changed, the data processing amount is reduced, the variety of the change of the display contents of the control bar is ensured, and the user experience is improved.

On the basis of the above embodiment, the setting of the target size is adjusted from a size in a first size range to a size in a second size range, the size of the second size range in the first target direction is smaller than the size of the first size range in the first target direction, and adjusting the display content of the control bar includes: and changing the arrangement direction of the controls in the control bar, wherein the arrangement direction is changed from a first target direction to a second target direction, the first target direction is a horizontal direction or a vertical direction, and the second target direction is a vertical direction of the first target direction.

Specifically, the first target direction may be a default arrangement direction of the control when the target display window is displayed in a full screen. When the first target direction is a horizontal direction, the second target direction is a vertical direction, and when the first target direction is a vertical direction, the second target direction is a horizontal direction.

The first size range and the second size range may be set according to actual conditions, and are independent of the third size range to the sixth size range. Preferably, the size of the second size range in the second target direction is larger than the minimum size value of the control bar at which the control can be displayed. For example, if the minimum value of the first size range in the first target direction is the minimum size value, and the target size is within the second size range, the minimum size value is smaller in the first target direction, and the size of the target display window in the second target direction is larger than the minimum size value, then the controls within the control bar are changed to be arranged in the second target direction to ensure that the control bar is displayed in the target display window.

Further, when the controls in the control bar are arranged in the second target direction, the specific display positions of the controls can be set according to actual conditions. For example, when the second target direction is a horizontal direction, the control bar position may refer to fig. 1, and when the second target direction is a vertical direction, the control bar position may refer to fig. 2.

Optionally, the display content of the control bar is determined according to the size of the target display window in the second target direction. For example, in the second target direction, the display content of the control bar corresponding to each size range is determined by dividing the display content into the third size range and the sixth size range. The embodiment of the determination rule of the display content is not limited. Optionally, when the target size is restored from the second display window to the first display window, the arrangement direction of the controls in the control bar may be changed from the second target direction to the first target direction.

For example, fig. 21 is a first schematic diagram of the target display window, and referring to fig. 21, the arrangement direction of the controls in the control bar 2103 is the horizontal direction, and the target size is within the first size range. When the user continues to shorten the size of the target display window in the horizontal direction, the target size enters the second size range. At this time, the target display window becomes fig. 22. Referring to fig. 22, the arrangement direction of the controls in the control column 2103 is the vertical direction, and all the controls are determined to be displayed according to the size of the target display window in the vertical direction.

It can be understood that when the controls in the control bar are arranged in the second target direction, the position arrangement of the other areas of the target display window except the control bar is not changed. Alternatively, the position of the region of the target display window other than the control bar changes following the second target direction. For example, the second target direction is a vertical direction, and when the arrangement in the control bar is changed into the second target direction, the positions of the touch writing area and the touch management area are adjusted to ensure that the content input sub-control bar and the touch writing area are displayed in the same line, and the content management sub-control bar and the touch management area are displayed in the same line.

In practical applications, it may be set that if the target size is smaller than the minimum size in the first target direction, the size of the target display window in the second target direction is determined; if the size is larger than the minimum size, changing the arrangement direction of the control from a first target direction to a second target direction; and then, continuously confirming the size of the target display window in the first target direction, and if the size is larger than the minimum size, changing the arrangement direction of the control from the second target direction to the first target direction.

In the above embodiment, when the target size of the target display window changes, the control bar can be changed along with the change of the target size by changing the arrangement direction of the controls in the control bar, and especially under the condition that the control bar cannot be displayed based on the target size, the display position of the control bar can be adjusted, so that the control bar is continuously displayed in the target display window.

EXAMPLE III

Fig. 23 is a flowchart of a control bar display method of an electronic whiteboard according to a third embodiment of the present invention. The present embodiment is embodied on the basis of the above-described embodiments. Specifically, referring to fig. 23, the method for displaying the control bar of the electronic whiteboard specifically includes:

s310, receiving the operation of adjusting the size of the frame.

Wherein the frame resizing operation acts on the target display window.

And S320, adjusting the target display window to a target size.

And determining the target size according to the frame size adjustment operation.

And S330, determining each control displayed in the control bar according to the target size.

Specifically, each control that needs to be displayed in the control bar under different display sizes is predetermined, and the corresponding relationship between each control and the different display sizes is recorded. When the target size is determined, the controls corresponding to the target size can be directly obtained according to the corresponding relationship. Optionally, the number of controls to be displayed in the control bar under different display sizes may be predetermined. Then, when the target size is determined, the number of the corresponding controls is determined according to the target size, and then the controls with the number equal to that of the controls are obtained. In this case, S330 may specifically be:

and S331, determining the number of controls corresponding to the target size.

Wherein the smaller the target size, the fewer the number of controls. The smaller the target size is, the smaller the length of the control bar in the target direction is, the smaller the area in the control bar in which the target controls can be displayed is, and correspondingly, the smaller the number of the target controls can be displayed is.

Specifically, the number of controls corresponding to different display sizes is preset, wherein the number of controls corresponding to different display sizes may be the same or different, and is specifically set according to an actual situation. For example, the display sizes are divided into A, B, C, D and E, with A > B > C > D > E. The number of the controls corresponding to the A is 7, the number of the controls corresponding to the B is 7, the number of the controls corresponding to the C is 5, the number of the controls corresponding to the D is 4, and the number of the controls corresponding to the E is 4. At this time, although there are the same number of controls for different display sizes, the smaller the target size is, the smaller the number of controls is satisfied as a whole.

Further, since the control bar includes a content input sub-control bar and a content management sub-control bar, setting the number of controls in the embodiment includes: the number of input controls displayed in the content input sub-control column and the number of management controls displayed in the content management sub-control column. Specifically, the number of input controls displayed in the content input sub-control column and the number of management controls displayed in the content management sub-control column are set in different display sizes. And when the number is 0, the corresponding child control bar is displayed in the screen in a cancelled mode. Further, since the content management sub-control column may include the content switching sub-control column and the content storage sub-control column, determining the number of content management sub-control columns includes determining the number of switching controls within the content switching sub-control column and determining the number of storage controls within the content storage sub-control column.

And S332, acquiring each control displayed in the control bar from all the controls to be displayed.

The number of the controls is equal to the number of the controls, and the controls to be displayed are preset controls which can be displayed in the control bar. Specifically, the control to be displayed may be selected by the user or selected by the control bar display device.

Further, when the control is selected, the selection may be performed according to the display priority of each control to be displayed, or may be performed according to the order of the initials of the controls to be displayed, or may be performed according to other selection rules. In an embodiment, the prioritization control is set to be displayed. At this time, the step specifically comprises: and selecting the control displayed in the control column from all the controls to be displayed according to the display priority of each control to be displayed.

Specifically, the display priority of each control to be displayed is determined, and the controls with the same number as the controls are selected according to the sequence from high display priority to low display priority.

Optionally, when a control displayed in the control column is selected from the controls to be displayed, an input control displayed in the content input sub-control column may be selected from the input controls to be displayed, and a management control displayed in the content management sub-control column may be selected from the management controls to be displayed.

Further optionally, when determining the number of controls, a simultaneous determination of whether to display the first alternate button may be made.

And S340, determining the display rule of each control according to the target size.

Wherein the display rules include: the display method comprises the following steps of displaying patterns of the controls, arranging sequence among the controls, arranging direction of the controls and displaying width of the controls. The display pattern comprises icons and/or Chinese names, and the arrangement sequence is the position sequence of each control in the control bar.

Specifically, the display rule of each control in each display size may be set in advance. When the target size is determined, the display rule of the corresponding control can be directly called according to the target size. And the display rule of each control can be determined in real time according to the target size. Wherein, this step specifically includes:

and S341, acquiring the display pattern of each control and the arrangement direction of the controls according to the target size.

Specifically, the display patterns of the controls in different display sizes are predetermined. The setting rule of the display pattern of each control can be set according to the actual situation. For example, within a certain size range, the display pattern of the input control includes an icon and a chinese name, and the display pattern of the management control includes an icon. In another size range, the display patterns of the input control and the management control are both icons.

Further, the arrangement direction of each control under different display sizes is preset. For example, the default arrangement direction is the horizontal direction, the target display window is set within a certain size range in the horizontal direction, the arrangement direction is the vertical direction, and the target display window is set within another size range in the horizontal direction.

And S342, determining the arrangement sequence of the controls according to a first set rule.

Wherein, the first setting rule can be set according to the actual situation. For example, the first setting rule includes: the display priority of the control, the use frequency of the control, the set display order of the control or the corresponding first letter sequence of the control.

When the controls are sorted according to the display priorities, the controls with high display priorities may be arranged at the front end of the control bar, and the controls with low display priorities may be arranged at the tail end of the control bar. Specifically, the display priorities of the controls in each child control bar are sorted, for example, an input control with a high display priority is displayed at the front end of the content input child control bar, and an input control with a low display priority is displayed at the tail end of the content input child control bar; when the controls are sorted according to the use frequency of the controls, the use frequency of the controls can be determined according to the number of times that the controls are clicked within the historical set time, the controls with high use frequency are arranged at the front end of the control bar, and the controls with low use frequency are arranged at the rear end of the control bar. Specifically, the use frequencies of the controls in the respective sub-control columns are sorted, for example, the input control with high use frequency is displayed at the front end of the content input sub-control column, and the input control with low use frequency is displayed at the tail end of the content input sub-control column; when the controls are arranged according to the set display sequence, the display sequence among the controls can be determined by a user, and then the display sequence is determined as the final display sequence of the controls; when the controls are ordered according to the initial ordering corresponding to the controls, the initial of the chinese name corresponding to the controls may be determined, and then the order of the controls may be determined according to the order of the english alphabet, for example, the input control with the initial a is arranged at the forefront of the content input child control bar, and the input control with the initial Z is arranged at the rearmost of the content input child control bar. If the same initial corresponds to a plurality of controls, the plurality of controls can be randomly ordered, or the order of the controls can be determined according to the initial of the second character of the Chinese name of the control.

And S343, calculating the display width of each control according to the display pattern and the target size.

Specifically, after each display pattern is determined, the display width of the display target in the control bar may be determined in accordance with the target size. When the display width is calculated, the size range to which the target size belongs may be determined, the minimum value of the size range is obtained, and the display width of the control is calculated according to the minimum value and the display pattern.

Alternatively, since the minimum values of the display pattern and the size range can be set in advance, the display width of each control can be calculated in advance. And when the display size is adjusted subsequently, the corresponding display width is directly adjusted according to the target size.

And S344, if the display width is smaller than the minimum display width of the control, taking the minimum display width as the display width of the control.

Further, considering that the target size is too small, if all the controls are displayed, the display pattern of the controls is too small, which is not beneficial to the operation of the user. Therefore, in the embodiment, the minimum display width of the display pattern is set, and when the display width obtained according to the display pattern and the target size is smaller than the minimum display width, the minimum display width is set and selected as the display width of the control.

And S345, calculating the sum of the minimum display widths.

The display width of each control can also be understood as the width of a child container allocated by the control bar display device for displaying the control. At this time, the display width is the minimum display width of the control. Further, the minimum display widths are added to confirm the total width required for displaying the target control, and the total width is recorded as a sum value. At this time, if it is set that the first alternative button is displayed only in a certain child control bar, the sum of the display widths of the controls in the child control bar may be calculated. For example, setting to display only the first alternative button in the content input sub-control bar, only the sum of the minimum display widths of the input controls is calculated.

S346, if the sum value is larger than the size of the control bar, confirming that the first alternative button is displayed.

And the size of the control bar is determined according to the target size. The control bar size may also be understood as the first length of the control bar, i.e., the width of the parent container in the control bar used to display the control. Optionally, each child control bar may correspond to a parent container, and at this time, the size of each child control bar may also be determined according to the target size. The size and value of each child control bar is a first length.

Further, after the sum is calculated, the sum is compared with the size of the control bar. Specifically, if the sum is the sum of the minimum display widths of the controls in a certain child control bar, the sum may be compared with the size of the child control bar. If the sum is smaller than the size of the control bar, it indicates that all the controls can be displayed in the control bar, and at this time, S350 may be executed. If the sum value is larger than the size of the control bar, only part of the control bar can be displayed in the control bar, and at this time, the first replacement button needs to be displayed in the control bar.

Optionally, after determining to display the first alternative button, the non-hidden control and the hidden control may be determined. For example, 6 controls are all provided, and 4 controls can be displayed in the control bar according to the target size, so that the 4 controls arranged in front can be selected as non-hidden controls according to the arrangement order of the controls, and the 2 controls arranged in back are hidden controls. It should be noted that, when the first replacement button is only displayed in a certain child control bar, the hidden control and the non-hidden control in the child control bar may be determined. Whether the controls of other sub-control columns are displayed in a cancellation mode depends on the number of controls displayed by the corresponding sub-control column.

Optionally, when the first replacement button is confirmed to be displayed, a display rule, a corresponding relationship with the size range, and a trigger condition of the second replacement button are also generated. And when the target size is determined to be in the corresponding size range, if the trigger condition is detected, displaying the second replacement button in the control bar according to the display rule of the second replacement button. For example, when it is detected that a first alternative button is clicked, it is determined that a trigger condition is detected, and a second alternative button is displayed in the control bar.

And S350, displaying the controls in the control bar according to the display rule.

Specifically, after the display rule is determined, each control is displayed in the control bar according to the display rule, so that the control bar changes along with the change of the target size.

Optionally, when it is determined that the first alternative button needs to be displayed in the control bar, the step further includes: and synchronously displaying the first replacement button to realize the replacement of the control in the control bar. Specifically, the first alternative button is displayed only in the content input sub-control bar due to the setting. Thus, the synchronized display of the first replacement button includes: a first alternative button is displayed in the content input sub-control bar.

According to the technical scheme, the technical means that the display position and the display size of each control in the internal control bar are fixed to cause that a user cannot call the control when the size of the display window of the application software is changed can be solved by receiving the frame size adjusting operation acting on the target display window, adjusting the target display window to the target size according to the frame size adjusting operation, determining the control and the display rule of the control according to the target size, and further displaying the control in the control bar according to the display rule of the control, so that the display style in the control bar is synchronously changed along with the display size of the display window. Meanwhile, the control and display rule are determined in a simple mode under different target sizes, the data processing amount of a system cannot be increased, and the synchronous change of control bars under all target sizes is conveniently and quickly realized.
