In other words, there may be one or more client screens, which are set according to specific application scenarios, and the embodiment is not limited.

Optionally, an electronic whiteboard is installed in the interactive smart tablet. Open the electronic whiteboard in the interactive smart tablet. At this time, the interactive smart tablet is equivalent to a large tablet. The user can write, draw and display on the display tablet of the interactive smart tablet. You can select the recognition language in the operating system's existing language pack, and then write.

A trajectory, a pattern formed by moving points that meet a certain condition, or a set of points that meet a certain condition, is called a trajectory of points that meet the condition. For example, handwriting written in chalk on a blackboard, traces of a finger stroke on a display tablet, etc., can be called handwriting. In the embodiment of the present invention, unless otherwise specified, the trajectory refers to a trace input by a user through a stylus or a finger on the display tablet.

The terminal interface can be understood as, for example, the interface of an application software such as an electronic whiteboard; or other interfaces having a text input function, and so on.

Objects, including at least any one or more of the following objects: formulas, chemical equations, 3D objects, pictures, videos, shapes, and so on. Of course, compatible with the prior art, the object in this article can also be text or text (a combination of multiple texts or texts and other types of objects).

The stream layout mode, that is, the document stream mode, refers to that an input object can automatically move forward and backward like a character, and supports selection like a single character.

Boundary layout, that is, the text control is divided into five areas: middle, north, west, east, and south. The input objects can be sequentially arranged in the middle, north, west, east, and south of the text control. It is preferentially arranged in one or more of them, and is set according to actual needs.

Grid layout method, that is, the text control is divided into multiple grids. The input objects can be sequentially arranged in each network of the text control, or the input objects are preferentially arranged in one or more of the grids, depending on the actual situation. Needs to be set.

The card layout method is similar to the card layout in the Graphical User Interface (GUI), and will not be repeated here.

Considering that the existing interactive smart tablet text controls only support text input, the current input requirements for text controls are not limited to text, but also include pictures, videos, etc. Therefore, based on the above findings, an embodiment of the present invention provides a method based on The object display method, device, and storage medium of the text control implement input of arbitrary objects in the text control of the interactive smart tablet through a preset layout.

FIG. 1 is a flowchart of a method for displaying an object based on a text control according to an embodiment of the present invention. The text control-based object display method can be executed by a text control-based object display device. The text control-based object display device may be implemented in a software and / or hardware manner. The text control-based object display device may include one or more physical entities.

In practical applications, the text display-based object display device may be a computer, a mobile phone, a tablet, a Personal Digital Assistant (PDA) or an interactive smart tablet. In the subsequent embodiments, the interactive smart tablet is taken as an example for a text control-based object display device for description.

Referring to FIG. 1, a method for displaying an object based on a text control provided in this embodiment includes:

S101. Receive an input operation of a user in a text control of a current terminal interface.

Among them, the input operation is used to enter an object in a text control. The specific form of input operation can be set according to the actual situation. For example, the interactive smart tablet may determine that an input operation is received when a touch operation performed by a user in a text control is detected. For another example, the interactive smart tablet may determine that an input operation is received when it receives data transmitted from another terminal device. The other terminal device may be a device such as a notebook computer connected to the interactive smart tablet. Alternatively, an insert button can be set. The insert button can be said to be a physical button or a virtual button, which can be located on the interactive smart tablet or on an external device connected to the interactive smart tablet. When the interactive smart tablet detects that the user triggers the operation of inserting the key, it is determined that an input operation is received. The operation of triggering the insert button by the user may be any one of clicking, double-clicking, and long-pressing. Exemplarily, a user wants to input a picture in a text control. At this time, the user can click an insert button for inserting a picture on the interactive smart tablet. Correspondingly, the interactive smart tablet receives an input operation for inputting the text control in the text control. Enter the object Picture.

In practical applications, the display panel of the interactive smart tablet is a touch screen, and the touch screen may specifically be a capacitive screen, an electromagnetic screen, or an infrared screen. Generally speaking, the touch screen can receive a touch operation input by a user through a finger or an input device. The input device includes, but is not limited to, a stylus pen, an infrared pen, and a capacitive pen. In the embodiment, an input operation is received in a manner of receiving a touch operation through a display tablet of an interactive smart tablet.

S102. Display the object in a text control by using a preset layout.

The preset layout mode refers to a relatively fixed position of each unit of the layout in the text control, and the input object automatically corresponds to the layout mode of each unit according to the preset layout. The preset layout method may include any one of the following layout methods: a streaming layout method, a border layout method, a grid layout method, and a card layout method.

Exemplarily, taking the flow layout method as an example, the objects are displayed in the text control by using the flow layout method. In this way, objects such as pictures and videos can support the flow layout method as text, and realize automatic line wrapping. For example, referring to FIG. 2, the input objects in the text control include text and shapes, where the shapes are specifically circles and rectangles.

The technical solution provided in this embodiment is to receive an input operation for inputting an object in a text control in a text control of a current terminal interface by a user, and then display the object in the text control in a preset layout manner, where The preset layout means that the positions of the units laid out in the text control are relatively fixed. The input object automatically corresponds to the layout of the units according to the preset layout. The preset layout includes any of the following layouts. : Stream layout, border layout, grid layout, and card layout. Due to the characteristics of the above-mentioned preset layout method, the display of the object in the text control is to render the object at the position of the corresponding unit in the text control, thereby implementing the input of any object in the text control of the interactive smart tablet.

Optionally, displaying the object in the text control by using a preset layout method may include: adopting the preset layout method and displaying the object in the text control according to the current preset format. When implemented, the text control corresponds to a preset format, that is, the current preset format, where the input object is displayed in the current preset format. Among them, the current preset format is, for example, the font is Times New Roman, the font size is small four, and so on.

FIG. 3 is a flowchart of a method for displaying an object based on a text control according to another embodiment of the present invention. Referring to FIG. 3, based on the foregoing embodiment, a method for displaying a text control-based object provided by this embodiment may include:

S301. Receive an input operation of a user in a text control of a current terminal interface.

This step is the same as S101, and is not repeated here.

In this embodiment, S102 shown in FIG. 1 and displaying the object in the text control by using a preset layout method may include the following steps:

S302. Obtain size information of the object.

Generally, the size information of an object is relatively fixed. For example, when the object is a picture, the length and height of the picture are fixed, or when the object is a formula, the length and height of the formula are fixed. Therefore, after receiving the input operation, the size information of the object can be acquired, and after that, S303 is performed.

S303. Adjust the size of the unit according to the size information.

The text control may include at least one unit.

Specifically, the text control is divided into different units according to the current preset format, as shown in FIG. 4. Exemplarily, if the current preset format includes a row height, the calculation of the row height is added when the unit size is calculated. Alternatively, if the current preset format includes paragraph indentation, when an object is subsequently displayed in the text control, the object display processing may be performed from the unit after the paragraph indentation.

When you enter an object in a text control, the size of the object may not match the size of the set unit. For example, the size of the target size is greater than the size of the set unit. At this time, the size of the unit needs to be adjusted to make the object For complete and clear display. Therefore, after obtaining the size information of the object, the size of the unit is adjusted according to the size information. It can be understood that the unit size here includes the length and height of the unit. Regarding the adjustment of the width of the unit, refer to FIG. 5 for understanding. As shown in FIG. 5, obviously, the width of the cell occupied by the letter “f” is smaller than the width of the letter “d” or “a”.

Optionally, when there are multiple objects, this step may include: determining a maximum height in the height information of the multiple objects; and setting the row height of the cells in the text control to be greater than or equal to the maximum height. The size information includes height information.

S304. Render the object to the unit pointed by the current cursor of the text control.

For example, for the flow layout method, when the number of objects is multiple, you can lay out from left to right to the corresponding unit of the text control according to the input order of the objects. When the width of the input object exceeds the width of the text control , Perform a newline, and layout on the next line.

Further, the method for displaying an object based on a text control may further include:

S305. Display a cursor at a position after the displayed object.

Still using Figure 5 as an example, the cursor is displayed after the last subtitle "d" of the text control. The length of the cursor can be the height of the unit, that is, the line height.

Because the object is displayed in the text control using a preset layout, the position of any object is fixed to the unit. When objects are added or deleted, the relevant unit is re-arranged, and the input object also supports the preset layout. .

Therefore, based on the above embodiment, after the object is displayed in the text control by using the preset layout, the method for displaying an object based on the text control may further include: moving the object behind the current cursor position backwards / towards Move down. Alternatively, the movement may include line breaks and segmentation.

It can be understood that, for the current paragraph, after the object is displayed in the text control, the object after the current cursor position is moved backwards / downwards. Paragraphs after the current paragraph are not moved / moved down.

When a carriage return instruction is detected, the object after the current cursor position is moved down.

It should be noted that the term "and / or" used in this article is only an association relationship describing the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can mean: A exists alone, and exists A and B, there are three cases of B alone.

In some embodiments, before receiving a user's input operation in a text control of a current terminal interface, the method may further include: receiving a cursor positioning instruction. This cursor positioning instruction is used to position the cursor in a text control. The cursor positioning methods include, but are not limited to, mouse positioning, keyboard movement, and touch and click positioning. With the cursor positioning instruction, you can position the cursor to any unit in the text control to achieve object input at any position in the text control.

The above embodiment specifically describes the implementation manner of inputting any object in the text control of the current terminal interface. Next, the processing of the input object in the text control will be described through different embodiments.

In an implementation manner, the method for displaying an object based on a text control may further include: receiving a selection instruction. This selection instruction is used to select some or all of the objects that have been entered in the text control. Through the selection instruction, you can select the input object in the text control.

Further, after receiving the selected instruction, the text control-based object display method may further include: receiving a format modification instruction. The format modification instruction is used to modify the format of the selected object. The format modification instruction may include a target object format; the selected object is displayed according to the target object format. Among them, the number of selected objects can be one or more, and the types of the selected objects can also be different, such as including pictures and text, and so on. The format modification instruction can modify the format of the input object in the text control.

In another implementation manner, the method for displaying an object based on a text control may further include: receiving a delete instruction. The delete instruction is used to delete some or all of all the objects that have been entered in the text control; the display of the object corresponding to the delete instruction is stopped, and the cursor is displayed after the previous object of the stopped display of the object.

In this implementation manner, the deletion instruction may be a deletion instruction corresponding to an object that has been entered before or after the cursor, and may be understood as a deletion of a single object; or, the deletion instruction may also be a deletion instruction corresponding to a selected object, and may be understood as a deletion instruction Deletion of selected single objects or batch objects.

Optionally, after the object corresponding to the delete instruction is stopped from being displayed, the method for displaying an object based on a text control may further include: moving the object after the object corresponding to the delete instruction forward / upward. The “forward / upward movement” here may correspond to the aforementioned “backward / downward movement”, which is not repeated here.

Through the technical solutions provided by the foregoing embodiments, a text control is customized from the aspects of object input, object display, object formatting, object selection, cursor display, and the like, so that each process of text editing can be completely controlled.

Among them, the text control can include the following parts:

The document manager includes a property manager and a document tree manager. Among them, the property manager is responsible for managing object properties and paragraph properties. The document tree manager is responsible for managing object content, including paragraph segmentation information and paragraph position information. Paragraph segmentation information requires high-performance algorithms to ensure that paragraphs can be quickly found and changed. Exemplarily, the high-performance algorithm may be a red-black tree or the like.

Rendering module: responsible for rendering the content of objects in the document tree manager into visible objects.

Layout layout module: Obtain paragraph position information from the document tree manager, and lay out the object content to the corresponding position of the text control.

Corresponding to the above embodiment, after the user positions the cursor in a text control and inputs an object, first, after receiving the object input, the document tree manager adds the content of the object corresponding to the object to the current paragraph. If it is deleted or Line wrapping, the document tree manager also does the corresponding paragraph management. After that, the property manager started to work. The property manager is responsible for managing the properties of the entire document, such as the vertical alignment of the entire text, the horizontal alignment of each paragraph, the boldness of each text, the underline, the font size, the font attributes, and so on. The newly entered object has the same format as the previous object by default, and the newly entered paragraph has the same format as the previous paragraph by default. The property manager makes the corresponding property changes after the document changes. Then, render the object. The rendering of the object is based on paragraphs, one paragraph and one paragraph. When the rendering module starts to work, it obtains the paragraph segmentation information of the document from the document tree manager, that is, what text each paragraph has, and then obtains the paragraph attributes of the paragraph and the object attributes of the objects in the paragraph from the property manager. Then start rendering. After rendering, one can get the rendered paragraph objects one by one. At this time, the paragraph position information is obtained from the document tree manager, and according to the paragraph position information, the rendered paragraph objects are laid out to the correct position, forming Finally visible text. After the text layout is completed, the position and size of the cursor need to be updated according to the paragraph position information in the document tree manager. At the same time, the selected content also needs to be updated. For example, if you select a section to reduce the font size, the selected effect must be corresponding Variety.
