Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a multi-window display control system, particularly in bank terminals and the like, and mainly controls the display position and position of windows on a display screen where multiple windows overlap.
The present invention relates to a window screen display control method suitable for changing the size.

[Background of the invention]

Conventionally, the method of changing the position of a window on a multi-window screen involves moving the window (temporarily deleting the window at the original position and then recreating the same window at the destination position). An example of such a method is ``Document processing system using multi-windows (■
)”. However, with these conventional methods, re-creating the window requires bitmap development of the display data (conversion from character code to character font, etc.), so it takes a lot of processing time to display the window position page. was. Furthermore, when changing the size of a window on the above-mentioned multi-window screen, a method was adopted in which the window before the size change was once deleted, the size was changed, and the window was created again. However, the intersection area (AND area) between the window area before the change and the window area after the change has the same content even after the size change, so there was a problem that erasing and redisplaying the area would be wasteful. .

In addition, as an example of related technology, Japanese Patent Application No. 59-876
Specification No. 86 is mentioned.

[Purpose of the invention]

It is an object of the present invention to solve these conventional problems, to change and display window positions on a multi-window screen with a small memory requirement and short processing time, and to change the window size on a multi-window screen. The object of the present invention is to provide a multi-window display control method that can perform operations at high speed.

[Summary of the invention]

In order to achieve the above object, there is provided a device that develops one image data into a bitmap and displays the bitmap-developed data in a multi-window by superimposing a plurality of windows on a display screen.

Before moving the window on the above screen based on the positional relationship information of the overlap of multiple windows displayed on the above screen,
The subsequent window display area is divided into an area where the image can be moved and an area where the image cannot be moved, and the bitmap data of the window is transferred between the image movable areas before and after the window is moved, so that the window position can be changed in a short time. It can be realized with , and it is also characterized by the ability to change the window size at high speed.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

This example is divided into (1) the first example (hereinafter referred to as the first example) and (TI) the second example (hereinafter referred to as the second example), and the window is A display control that allows the position to be changed and a display control that allows the window to be quickly resized will be explained.

First, the present invention will be explained in detail.

In the first embodiment, the movement of the window has conventionally been realized by erasing and recreating the window, but recreating (re-developing the bitmap) takes time. In the present invention,
By transferring the bitmap data of the window at the source to the destination, it is no longer necessary to recreate the window.

However, if another window overlaps the window to be moved, the possible area for bitmap data transfer is calculated based on the overlap situation, and then the bitmap data is transferred between the possible areas before and after the movement. I decided to do this.

In the second embodiment, the window size change display is performed by displaying the visible area of only the enlarged part of the window, and
This is done by combining the visualization area of the window group that overlaps under the relevant window in the size reduction range and the display of the visualization area of the screen background.This allows the resizing without changing the display of the intersection area of the window areas before and after the resizing. Improved processing performance. The display of the enlarged range and the reduced range (display of only the visible area based on the superimposed state of the windows) can be calculated and displayed by repeating the rectangular division based on the intersecting state of the window and other windows.

(I) First Embodiment FIG. 2 is a main configuration diagram of a display device to which the present invention is applied.

This display device consists of 1 main memory 12 which stores various data of CPU II which performs display control processing, display refresh memory 13 which outputs display control processing results. It is composed of a display 14 on which a multi-window screen is displayed.

FIG. 3 is a diagram showing an example of changing the window position on the multi-window display screen according to this embodiment. This is the display screen 2 of the display 14 shown in FIG.
1 shows a situation where three windows are displayed and one of the windows is moved to another area.

In FIG. 3, 21 is a display screen on the display 14, 22 to 24 are windows displayed on the display screen 21, 25 is an area representing the destination of the window 24 (hereinafter referred to as the destination window area), 241
is the image movement source area in the display-required area in the window 24, 251 is the movement destination window (image movement destination area in the area 25, 252 is the image movement destination area 251 from the image movement area 251 in the movement destination window area 25) Area excluding (hereinafter,
This is called the re-bitmap development area).

FIG. 1 is a processing flowchart for explaining a multi-window control method showing a first embodiment of the present invention.

This consists of the CPU 1 and main memory 12 shown in Figure 1.
This figure shows the procedure for display control processing performed between. Hereinafter, the process will be explained according to the flowchart of FIG. 1 while referring to the display screen of FIG. 2.

First, a redisplay area within the window area 25 is determined based on the intersecting relationship between the window area 25 after the position change and the window 23 overlapping the window area 25 (step 101). Next, an area in the window 24 corresponding to the redisplay area in the window 25 (redisplay area) is determined (step 102). Due to the intersecting relationship with the window 22 that overlaps above), the image movement within the area that requires redisplay within the window 24 due to the intersecting relationship between the area that requires redisplay within the window 24 and the window 22 that overlaps above the window 24. Original area 241
(step 103), and then find the image movement destination area 251 in the movement destination window area 25 that corresponds to the image movement source area 241 in the window 24 (step 1
04). The image data (bitmap data on the display refresh memory 13) is transferred between the image movement source and movement destination areas obtained in steps 103 and 104 above (step 105), and the bitmap redevelopment area 252 in the window area 25 A bitmap layer table is performed (step 106).

Next, recover the screen below with window 24 removed.

There may be multiple windows overlapping under the window 24, but only the necessary parts of the overlapping windows are divided into rectangles based on the positional relationship of the windows at that time and the intersection of the window with other windows. It is possible to calculate and redisplay by repeating the process.

Through the above procedure, the window area after the movement is displayed by a combination of transferring the image data of the window before the movement and re-bitmap expansion.

Furthermore, at the source of the movement, the screen below the window before the movement is restored, and as a result, the window is erased at the position before the movement and is displayed at the position after the movement.

In this way, in the first embodiment, the window 24 is
By transferring the bitmap data of the movement source window 24 to the movement destination (window area 25) when changing the position of the movement source window 24.

Since there is no need to re-expand the bitmap of the window at the destination, the window position change process can be sped up.

(I) Second Embodiment The configuration for realizing the second embodiment is the same as that shown in FIG. 2, so the explanation is omitted here and please refer to the first embodiment. ~A second embodiment will be described using FIG.

FIGS. 4 and 5 are diagrams showing an example of changing the window size on a multi-window screen according to this embodiment.

In FIG. 4, the display screen 41J of the display 14
:, when three windows 42 to 44 are displayed,
5 shows a virtual screen 51 where the display range (area) 52 of the window 22 in FIG. 4 exists. . Conversely, the display range 5 on the virtual screen 51
Only the display data of part 2 is displayed in the window 42 on the actual display screen 41. By expanding the window horizontally, the area 4 on the actual screen 41
Only the display data of the area 57 corresponding to number 7 is displayed from the virtual screen to the actual screen.

In addition to the virtual screen 51, there is a separate virtual screen (not shown in the figure) that has a display range corresponding to the windows 43 and 44), and as the window is reduced, the lower window 4
4 is visualized, display data on the virtual screen 51 corresponding to the visualized area 48 is displayed in the area 48 of the actual screen 41. The virtual screen 51 here is located on the main memory 12, and only the data in the display range is developed into a bitmap (converting character codes to character fonts, etc.) on the display refresh memory 13 by the CPU II, and then transferred from the display refresh memory 13. It is displayed by refreshing the display 14.

Note that the display data may already be expanded into a bitmap on the virtual screen 51, but in this case, a large amount of memory is required.

FIG. 6 is a processing flowchart for explaining a multi-window display control method showing a second embodiment of the present invention. This shows the procedure of display control processing performed between the CPU 11 and the main memory 12 shown in FIG. Hereinafter, explanation will be given according to FIG. 6 using FIGS. 4 and 5.

First, the enlarged area 45 and reduced area (area) 46 of the window 42 are calculated from the window size before the change and the window size after the change (step 601). Next, the enlarged area 45 is calculated as described above. By applying the multi-window sequential split display method, out of the enlarged area 45,
Only the area 47 that is not covered by the upper window group is displayed (step 602), and then the reduced range (area) 4
6, the multi-window sequential split display method described above is applied, and the visualized portion is displayed by deleting the area 46. In the case of FIG. 4, the visualized area is a part of the window 44. They are an area 48 and an area 49 that is part of the background of one screen. (Step 603).

Through the above procedure, the area 45 of the window 42 has been enlarged and the range 46 has been reduced. The window overlap order subject to the sequential division amount in step 602 is only the second from the top. On the other hand, step 6 above
The overlapping order of the windows to be sequentially divided and displayed in 03 is determined by the screen background starting from the next order of the resizing window.

In this way, in the second embodiment, when changing the size of the window 42 on the display screen 41 where a plurality of windows overlap, only the visualization area of the window enlargement area and reduction range is adjusted based on the overlapped positional relationship of the plurality of windows. Since it is calculated and displayed based on , the performance of window resizing processing can be improved.

〔Effect of the invention〕

As explained above, according to the present invention, when changing the position of a window on a display screen where multiple windows overlap, it is possible to eliminate the need to re-bitmap the window at the destination. It is possible to speed up processing and improve the performance of window size change processing.
