Abstract

PURPOSE:To easily confirm windows hidden below by displaying the state display picture, which indicates the state of overlapping of plural windows seen from the side, overlapping windows. CONSTITUTION:A state display picture 5 is displayed which indicates the state on a display screen 1 of overlapping multiwindows 2-4 seen from the just side, and this state display picture 5 is used to pick required one of windows 2-4 by a mouse or the like. In this case, said state display picture 5 is displayed in the highest position of pictures displayed at present. Consequently, an operator picks a specific picture in the state display picture 5 to transfer the conversation right to this picked picture, and this picture is displayed in the highest position overlapping the other pictures. Thus a window hidden under plural windows 2-4 is easily found.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multi-window display system, and particularly to a multi-window display system that can easily surprise a window hidden at the bottom and give dialogue rights. Regarding the display method.

[Conventional technology]

As a conventional technique related to a multi-window display method, for example, a technique described in Japanese Patent Laid-Open No. 60-227293 is known. This kind of prior art is capable of displaying a plurality of screens at high speed by displaying the topmost window by controlling a window detection unit and a multiplexer.

[Problem to be solved by the invention]

Although the above-mentioned conventional technology can display multiple screens at high speed, it does not take into account operations for windows hidden below, and has poor operability, especially when windows hidden below. The problem is that it is difficult to easily perform the processing in an interactive manner.

An object of the present invention is to solve the problems of the prior art, and in an overlapping multi-window display method in which windows are displayed overlapping each other, it is possible to easily recognize a window hidden below, and to pick this window. The object of the present invention is to provide a multi-window display method that allows interactive processing.

[Means to solve the problem]

According to the present invention, the purpose is to display a status display screen that shows the status of overlapping multi-window display screens viewed from the side, and use this status display screen to select necessary windows using a mouse or the like. This is achieved by being able to surprise.

[For production]

A status display screen showing the status of the display screen when viewed from the side is displayed at the top of the currently displayed screen. By clicking a specific screen on the status display screen, the operator can transfer the dialogue right to the picked screen and display the seventh screen in an overlapping manner at the top.

〔Example〕

Hereinafter, one embodiment of the multi-window display method according to the present invention will be described in detail with reference to the drawings.

FIGS. 1, 2, and 3 are diagrams for explaining the display situation of an embodiment of the present invention, FIG. 4 is a block diagram showing an embodiment of a data processing device that implements the system of the present invention, and FIG. 6 are diagrams explaining the window management table. Figure 1~
In FIG. 4, 1 is a display screen, 2 to 4 are first to third windows, 5 is a status display screen, 6 is a side display, 11 is a memory, 12 is a processing device, 13 is a display control device, and 14 is a display 15 is an internal bus, and 21 is a window management table.

As shown in FIG. 4, the data processing device implementing the present invention connects the processing device 12 and the memory
1 and a display control device 13 are connected, and a display device 14 is further connected to the display control device 13. A program for controlling the present invention is a memory 1.
1, and by controlling the display control device 13, multi-window display is performed on the display device 14.

FIG. 1 shows a situation where three screens are displayed in an overlapping manner. In the display screen 1 of the display device [14, there are 3
Three screens are displayed in order from the top: a 71st window 2, a second window 3, and a third window 4.

In this way, window 2 is displayed in an overlapping manner.
When viewing windows 2 to 4 from the right side, it appears that three windows 2 to 4 overlap each other, as shown in the side view 6 in FIG. Therefore, in this example, the entire screen of the first window 2 and the second window 3 are displayed on the actual display screen 1.
A part of the screen is displayed, and the third window 4 is not displayed and cannot be seen from the front.

Such display processing is performed using a window management table 21 as shown in FIG. That is, the window management table 21 is configured to include a window number, start point and end point information indicating the window rectangular area, and window hierarchy number for each window. Based on the start point and end point information, the information is displayed sequentially from the upper layer. The start point and end point information of each window is represented by the X and Y coordinates of the opposite vertices of the window rectangle, that is, the upper left corner and lower right corner, and the window hierarchy is as follows:
It is assumed that the one with the smaller hierarchy number is the upper hierarchy.

It is also assumed that the coordinates of the upper left corner of the display screen 1 are (0,0) and the coordinates of the lower right corner are (699°449).

Now, when the display device 14 is displaying as shown in the display screen 1 of FIG. 1, if the operator performs a status display request operation using, for example, a mouse (not shown), the The display is changed as shown as display screen 1 in FIG.

That is, at this time, the topmost layer of the display screen 1 includes the first
Status display screen 5 similar to that described as side display 6 in the figure
is displayed. This status display screen 5 displays a screen that shows a plurality of windows displayed on the display screen 1 from the right side, so that the overlapping of the windows can be seen. This l-shaped display is based on the Yo, Y1 coordinates and layer number of each window in the window management table 21 shown in FIG. This is done by displaying a thick vertical line for the length between Y and Y. Therefore, in this case, the status display screen 5 will display the first window 2, the second window 3, and the third window 4 in order from the left side.

While the display on the display device 14 is being displayed as shown in the display screen 1 of FIG. 2 as described above, the operator uses a mouse or the like to start the third window 4 in the status display screen 5. When the operation is performed, the state of the display screen 1 is changed as shown in FIG. 3, and at the same time, the state display screen 5 is erased. That is, by picking this third window 4, the third window 4, which was not visible until now, is displayed on the top layer of the display screen 1, and the dialog right is also transferred to the screen displayed in this third window 4. The operator can perform processing by interacting with this screen. At this time, the first window 2, which was currently displayed on the top layer of the display screen 1, is moved to the next layer, and the second window 3 is also moved to a lower layer. With this screen transition, only the layer number portion of the window management table 21 is changed, as shown in FIG. 6.

In the embodiment of the present invention described above, the number of windows to be displayed has been described as three, but it goes without saying that the number of windows may be arbitrary.

As described above, according to the embodiment of the present invention, no matter how many windows are displayed in an overlapping manner, a necessary window can be easily found and called, thereby improving the usability of the system. .

〔Effect of the invention〕

As described above, according to the present invention, it is possible to easily find a window hidden behind a plurality of windows in a multi-window display method using wrap display, and to provide a system with good operability. Can be done.
