Abstract

PURPOSE:To always perform an instruction operation precisely at the time of changing a display state by displaying a frame shape part of format corresponding to change specification by switching to the outer edge part of a window screen corresponding to the designation of a designation means. CONSTITUTION:A window control means 11 executes window control decided in advance corresponding to each area replying to an area instruction operation of the designation means 12. For example, when size is changed, the screen size of a window is changed rightward and leftward, or upward and downward by moving a side corresponding to a designated area. When scrolling is performed, the display screen of the window is scrolled in a direction corresponding to the designated area. Therefore, the frame shape part corresponding to the change specification can be displayed selectively at need. In such a way, since no display screen of a display part is occupied widely and the required minimum area section is displayed on the frame shape part, a selective operation for that can be easily performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window display control device which has a window display function and has improved instruction operations when changing the display state of a window screen.

[Conventional technology]

There is a device that displays a window screen on a part of the entire display screen of a display unit. These window screens are displayed at various positions and in various sizes on the entire display screen of the display unit. In such a device, in order to change the display state such as changing the size of the window screen and scrolling, it is necessary to set an icon at a fixed position on the display screen of the display unit, regardless of the display position of the window screen. Operate the indicator using a mouse, etc. This instruction operation requires multiple steps of operation depending on the stepwise display of the indicator.

[Problem to be solved by the invention]

Indicators such as icons related to the window screen are provided at fixed positions that are unrelated to the display position of the window screen, so the operability is significantly degraded if instructions such as icons are operated while looking at the display status of the window screen. At the same time, it becomes difficult to set the window screen to an appropriate display state. Furthermore, since the instruction operation requires a plurality of steps of operation according to the stepwise display of the indicator, there is a problem in that the workability is poor. In addition, there are various ways to change the display state of a window screen, such as changing the size, scrolling, and moving. Providing a large number of indicators for each type of change makes it easier to select and display indicators during operation. There are problems with screen occupancy, etc.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to always properly perform an instruction operation when changing the display state of a window screen according to the display position of the window screen.

[Means to solve the problem]

The means of this invention are as follows.

A display unit having a display screen for displaying a window, a specification means for specifying the type of change such as resizing or scrolling the window screen, and a predetermined method corresponding to each change type according to the specification of the change type by this specifying means. means for forming a frame-like part corresponding to the specified change type among each frame-like part having a plurality of regions at the outer edge of the window; means for indicating the area of the frame-like part; The apparatus further comprises a window control means for executing predetermined window screen control according to the area designated by the above, and controls the outer edge of the window screen according to the designation of the designation means to create a frame-like part in a format corresponding to the change type. This is to switch the display to the section.

[Effect]

A window is displayed on the display section, and a frame-shaped section is further formed at the outer edge of the window by the forming means. The frame-shaped part has a plurality of predetermined areas corresponding to each change type, and among each frame-shaped part, the change type specified by the above-mentioned specifying means can be selected by operating a mouse or the like. Specify the type of change, such as resizing or scrolling, using the means. For example, when the change type of resize is specified,
The forming means displays on the outer edge of the window a frame portion divided into areas according to the number of specific instructions for resizing. Further, when a scroll change type is specified, the forming means displays a frame-shaped portion divided into areas according to the number of specific scroll instruction contents on the outer edge of the window.

When a frame-shaped portion for size change is displayed, a mouse or the like is operated to indicate a predetermined area of the frame-shaped portion using the indicating means. For example, if you want to widen the right side of the window screen, you can point to the area on the right side of the window and move the area to the right by the amount you want to widen. When the scroll frame portion is displayed, the user operates a mouse or the like to designate a predetermined area of the frame portion using the pointing means. For example, if the user wants to scroll the window display screen to the right, he or she performs an operation to specify an area indicating rightward scrolling.

The window control means executes predetermined window control according to each region in response to the region designation operation of the designation means. For example, in the case of resizing, the screen size of the window is changed horizontally or vertically by moving the side corresponding to the designated area. In the case of scrolling, the window display screen is scrolled in the direction corresponding to the designated area.

In this way, a frame-shaped part is provided at the outer edge of the window, and this bar-shaped part is selectively displayed according to the type of change, and each frame-shaped part divides the area according to the number of specific instructions. Because it is set up so that no matter what display position the window screen is,
Since the frame of the window is located integrally with the display position of the window, it is possible to perform instruction operations continuously and smoothly while always referring to the display state of the window screen. Display control can be instructed. Furthermore, since the frame-like part according to the change type can be selectively displayed as needed, it does not take up a large area of the display screen of the display section, and the minimum necessary area division is displayed in the frame-like part. This makes the selection operation easier.

The operation of this embodiment will be explained below.

When the microprocessor unit 11 recognizes from the value of the cursor pointer 12 and the mouse switch-on operation that a window display item has been selected from the screen editing menu and one window has been selected from the subsequent menu, it generates a window width signal. The circuit I7, priority circuit 18, and offset memory IJ19 are each controlled to display the specified window on the CRT display 13. That is, the window width signal generating circuit 17 is controlled by the microprocessor unit 11.
It synchronizes with the synchronization signal from the RT controller +5 and outputs a window width signal at the display timing of the window to be displayed. This window width signal is input to the priority circuit l8. The priority circuit l8 is connected to the microprocessor unit 1! Under the control of , the priority order based on the overlap of windows to be displayed is determined, and the window width signal received from the window width signal generation circuit 17 is selectively outputted according to the priority order.

The window width signal output from this priority circuit l8 is supplied to an offset memory l9. Offset memory! 9 outputs the offset address of the window in synchronization with the window width signal received from the priority circuit 18. This offset address is CRT:l
It is input to the adder 20 together with the display address output from the controller 15, and the offset address of the window to be displayed is added to the display address. This adder 20
The display address output from the RAM 14 is given to the RAM 14 via the address selector IG. This allows R
The read address of AM14 is switched from the main display area to the window display area every time the window to be displayed is displayed, and during that time, the data in the window display area is sent to the CRT display I3, and the main display including the window change menu is switched from the main display area to the window display area. The specified window screen is displayed within the screen. The display screen displayed on the CRT display l3 at this time is shown in FIG. 3(a), and the RAM1
The data correspondence within 4 is shown in FIG. 4(a).

Here, when the [Size] area is specified by a mouse cursor movement operation in order to change the window size, for example, from the window change menu, the area specification is recognized by the microprocessor unit 11. When the microprocessor unit 11 recognizes this window size change designation, it displays the above-mentioned [SizeCo] area in a reverse display state and displays the display data in the window frame display area around the window in the main display area of the NRAM14 in the same R A
It is temporarily saved to a predetermined non-display area in M14, and frame data corresponding to [Size] is written in that area.

As a result, a window screen with a window frame (F) added is displayed on the CRT display l3. The display screen displayed on the CRT display l3 at this time is shown in FIG. 3(b), and the data correspondence in the RAM 14 is shown in FIG. 4(b).

Next, by moving the cursor with the mouse, a command area within the window frame (F) is specified according to the content of the size change. That is, when changing the fixed size of the window, r as shown in FIG. 8 in area A3 of the window frame (F)
L.J. rDJ, “?VIJ” Specify any area of “S” with the cursor.

For example, by selecting rLJ, the maximum screen (horizontal 720
dots (45 characters) x 920 dots vertically (48 lines)), and by selecting "D" the default screen (688 dots horizontally (43 characters) x 900 dots vertically (45 lines))
By selecting "M", the intermediate screen (horizontal 35
2 dots (22 characters) x 4 GO dots vertically (23 lines)), and by selecting "S" the screen becomes the smallest screen (9C dots horizontally (6 characters) x 120 dots vertically (6 lines)).

When resizing a part of the window, specify other areas (AI-A8) with the cursor, excluding the areas (L, DMS) within the window frame (F). That is, when changing the horizontal size, specify either area AI or A2 corresponding to the left or right side of the window frame (F) by moving the mouse cursor, and when changing the vertical size, specify either area AI or A2 corresponding to the left or right side of the window frame (F). In the same operation as above, specify either area A3 or A4 corresponding to the top or bottom side of the same frame, and when changing the size to the upper left or lower right direction, specify area A5 or A6 corresponding to the corner, When changing the size to the upper right or lower left, area A corresponding to the corner? , A8. Figure 3,
In FIG. 4, either AI or A2 is designated, the mouse switch is turned on, and the mouse is moved in the wand position. Since we are changing the size horizontally, move the mouse horizontally. The operating direction at this time does not need to be directly horizontal, but may be an oblique direction (vector direction).

The microprocessor I1 sequentially reads signals associated with mouse switch operations and cursor movement, recognizes the specified direction of the window size and the amount of change thereof, and controls the output signal width of the window width signal generation circuit I7 each time. , variably controls the window area according to the amount of mouse movement. As a result, the horizontal size of the window displayed on the display screen of the CRT display l3 changes as the mouse moves. The display screen displayed on the CRT display l3 at this time is shown in FIG.
The data correspondence within 14 is shown in FIG. 4(C).

When the mouse reaches a predetermined window size, the mouse is turned off and turned off, so that the microprocessor H recognizes this state. The microprocessor l1 recognizes that the window resizing operation has been completed by switching off the mouse.

After that, by moving the mouse cursor to select the above [Size] area again and turning on the mouse, the display of the window frame (F) is canceled and the window frame (F) on the display screen is , read out the saved data of that part and return it to the main screen display, and display the resized window on the display screen together with the window change menu shown in FIG. 3(a) above; Set the display mode to a mode where the window can be changed again.

The above has been described using the example of changing the horizontal size of the window. For example, when changing the size to the top left or bottom right of the display screen, the area A5 corresponding to the corner of the window frame (F)
, AG with the cursor and move the mouse in the above vector direction, the side AI. A3 or A2,
A4 is moved and the size is changed toward the upper left or lower right. Also, when resizing to the top right or bottom left of the display screen, specify areas A7 and A8 corresponding to the corners of the window frame (F) with the cursor and move the mouse in the direction of the vector above to change the corners. Constituting A2, A3 or AI,
A4 is moved and the size is changed toward the upper right or lower left. Further, when changing the size in the vertical direction on the display screen, it is sufficient to specify areas A3 and A4 of the window frame (F) with a cursor and move the mouse in the vertical direction.

Also, when moving the window in any direction, select [After selecting the area to move] from the window change menu above.
All you have to do is operate the mouse in the same way as when changing the size above. That is, for example, when moving a window horizontally, you can specify areas AI and A2 of the window frame (F) with the cursor and operate the mouse horizontally, and when moving the window vertically, you can move the window horizontally. All you have to do is specify areas A 3 and A 4 of the window frame (F) with the cursor and operate the mouse up and down.Also, when moving the window to the upper left or lower right, use area A of the window frame (F). 5
, A G with the cursor and operate the mouse in the above vector direction. Also, when moving the window to the upper right or lower left direction, move the area AT, of the window frame (F).
All you have to do is specify A8 with the cursor and move the mouse in the direction of the vector.

When the window screen is moved, offset memory is stored under the control of the microprocessor unit 11 as the mouse is moved. The offset value of the display target window in S is rewritten. Since these operations and processing means are easily understood from the above-mentioned size change processing operation, the explanation of the operation will be omitted here.

To scroll the window screen in any direction, select the [Scroll] area from the window change menu by moving the mouse cursor, and then click the window frame (F ) After selecting the desired scroll direction, turn on the mouse switch each time you scroll. That is, for example, when sequentially scrolling the window screen in the horizontal direction, the areas Bl, B2 or B3, B of the window frame (F) shown in FIG.
Specify one of the areas in 4 with the cursor and turn on the mouse switch sequentially each time you scroll. Also, when scrolling the window screen sequentially in the vertical direction, select the area B 5, B G of the window frame (F). Or B7. B Specify one of the areas in 8 with the cursor and operate the mouse switch sequentially each time you scroll. Also, when switching the window screen to the previous page sequentially, specify area B8 or BIO of the window frame (F) with the cursor, and then turn on the mouse switch in sequence each time the page is changed. When switching to the next page, area BI1 of the window frame (F)
Alternatively, after specifying B12 with the cursor, the mouse switch may be turned on sequentially each time the page is changed.

Also, by selecting the [Scroll] area again from the window change menu and turning on the mouse switch, the window frame (F) shown in FIG. 8 is erased.

As described above, by specifying the window change menu and the window frame (F) on the display screen using the mouse, various window change operations can be performed easily and quickly.

In the above embodiment, the window is surrounded by a window frame (F), and commands are divided into areas within that frame. A display form including a command designation area may also be used.

Further, in the above embodiment, menu selection and item selection are all performed using a mouse, but the invention is not limited to this, and other input means may be used.

〔Effect of the invention〕

According to the present invention, no matter what display position the window screen is in, the frame portion of the window is positioned integrally with the display position of the window. Display state change instruction operations can be performed continuously and smoothly, making it easier to correspond between the window to be changed and the change operation, and allowing individual display control to be specified depending on the area to be specified. Since the limited area divisions are displayed, the selection operation becomes easy.
