Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a display device provided in a personal computer, a workstation, etc. and capable of multi-window display.

B) Conventional technology Display devices typified by CRTs and liquid crystal displays, which are conventionally provided in information processing devices such as personal computers and workstations, have been made multifunctional such as image enlargement, reduction, or rotation. . One of them is a multi-window display, which displays or splits a plurality of screens on one display screen. (For example, a personal computer "MBC-680" manufactured by Sanyo Electric Co., Ltd. that can display multiple windows
0 ”). In a normal multi-window display image,
The number of windows can be increased, decreased, resized, moved, etc. by inputting from the keyboard or mouse.

(C) Problems to be solved by the invention Fig. 4 shows a display example of a multi-window in which windows are overlapped. If the window A (41) opened to the front is large, the window B located after it is large.
(42), window C (43) is hidden.

In the multi-window display, the execution status of each job under the operation of the multi-job that executes a plurality of jobs at the same time can be displayed at the same time, or the information on the screen can be instructed by the keyboard or the mouse. However, if there is a window that is partially or wholly hidden by the window in the foreground, the operator may not be able to fully confirm the display contents, or there is a risk of overlooking the hidden window without noticing the overlap.

D) Means for solving the problems The present invention is a display device capable of simultaneously displaying a plurality of windows on the display screen of the display means, and is provided with counting means for counting the number of displayed windows, The contents of the counting means are displayed on the display screen of the display means.

(E) Action The number of windows displayed by the display means is counted by the counting means, and the number is displayed on the display screen of the display means, so that there is another window hidden by the window. Even so, by looking at the number displayed,
Overlooking hidden windows is prevented.

F) Embodiment FIG. 1 is a schematic configuration diagram of an embodiment of the present invention. (1) is a control unit for controlling the entire apparatus, (2) is a CRT as display means (other liquid crystal or plasma display may be used), and (3) is display information as display contents of the CRT (2). And (4) and (5) are a video memory for storing, and a keyboard and a mouse as input means, which are connected to the control unit (1) through an interface (6).
(7) is an image memory which stores display information of images of each window corresponding to each of a plurality of windows, (8) is a window management memory, which is a screen management table (8a) as counting means, A window management table (8b) for management and a split image management table (8c) for management of split display are provided.

In the case of multi-window display, the control unit (1) first reads the display information, which is the display content of the window, from the image memory (7) in the window display order (from the innermost side), and the video memory (3). Sequentially store in the position corresponding to the predetermined display position of each window. Then, the control unit (1) updates the contents of each table of the window management memory (8) as shown in FIG. That is, every time the display information of one window is read out from the image memory (7) and stored in the video memory (3) in the screen management table (8a), the number N of display windows is increased by 1 and the display order of each window is changed. A certain window number n is added.
The window management table (8b) has a window position and size for each window, or an image memory (7).
The position of the display information inside is registered. The content of this table increases or decreases depending on the number of display windows. In the divided image management table (8c), the window number n and the position information of the windows to be divided and displayed when the window displays are not overlapped but are divided and displayed are registered.

Whenever the display information of the window is written from the image memory (7) to the video memory (3) by the control unit (1), it is CR.
A window is opened and displayed at T (2). At the same time, the control unit (1) reads the number of display windows by looking at the contents of the image management table (8a), and writes the display information indicating the number of display windows in a predetermined portion of the video memory (3), whereby the CRT (2 ) Display the number of windows on the display screen.

FIG. 3 is an example of a display image of the CRT (2). Window 1 (31), window (32), window 3 (33) are displayed in this order, and now window 3 (33) is on top.
Is displayed. The entire window 1 (31) is hidden from the display screen because part of the window 2 (32) is hidden by the window 3 (33). In the display screen, (34) is a display window number display area in which the number of windows currently displayed, that is, 3 is displayed.
The number of display windows is a value stored in the screen management table (8a), and the control unit (1) reads and displays the content on the CRT (2).

When I look at the CRT (2) screen, I can see only window 3 (33) and window 2 (32), but when I look at the display window number display area (34), it is "3", and another window is displayed ( You can see that it is not visible on the CRT (2) screen). Therefore, window 3 (33) is deleted. Then, a part of the window (31) and the window 2 (32) hidden behind the window 3 (33) appears. At the same time, the control unit (1) changes the contents of the screen management table (8a) and the window management table (8b), (-1 of the number of display windows N and window 3 (33).
(The information related to it is deleted) and the value of the display window number display area (34) is set to "2" according to the contents of the screen management table (8a)
And

When a window is newly opened from the state shown in FIG. 3, the contents of the screen management table (8a) and the window management table (8b) or the divided image management table (8c) are updated to display the number of display windows (34 ) Value to "4"
And

The operation command and the like are input by the keyboard (4) and the mouse (5). For example, as shown in FIG. 5, the cursor (51) is moved with the mouse (5) and "Move selection" or "1", "2", "3" is designated, and A, B in FIG. 5), Enter the location information. "Process selection", "1", "2", and "3" are pre-assigned to the operation command options, and the corresponding options are displayed according to the input position information (Fig. 5). C, D). Similarly, by moving the cursor (51) to the position of the desired option and inputting, the control unit (1) performs the control operation according to the operation command of the selected selection.

G) Effect of the invention As is apparent from the above description, the invention is such that the number of set windows is counted in the screen management table and the CRT is used.
The number is displayed on the screen. Therefore, since the number of windows is displayed even if there is a window hidden by the front window, it is possible to prevent the hidden window from being overlooked. Therefore, each job can give an appropriate instruction.
