[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window display control method, and more particularly to a window display control method for displaying a plurality of windows.

[0002]

2. Description of the Related Art Recently, in information processing devices such as computer systems and word processors, a window system has been developed and used as a graphical user interface (hereinafter referred to as GUI) that facilitates operation. In this window system,
Display a window screen, display various application programs and commands with icons on the window screen, move the cursor to the desired icon by mouse operation, specify it, and click the mouse button on the specified icon As a result, the application program and command processing are executed.

Further, in the window display control processing in the word processor, for example, in order to manage the display positions and display contents of a plurality of windows, a VRAM (video) for rewritably storing display text data, graphic data and the like. A window management area is set in RAM).

In the window management area, when a new window is opened while the window is already open, the background window data is saved, or the window data larger than the memory capacity is saved. If you open a new window with a non-fixed memory area (hereinafter called the soft window area) that stores window data that is overwritten and opened sequentially, do not save the opened window data. Further, a fixed memory area (hereinafter referred to as a hard window area) for storing window data of a window which is displayed as a background and is preferentially displayed is formed.

The hard window area is a VRAM.
Since it is necessary to use the internal memory area in a fixed manner, the memory capacity for opening one hard window is secured in order to effectively use the memory resources economically.

Therefore, a plurality of soft windows managed by the soft window area can be opened, and one hard window managed by the hard window area can be opened.

[0007]

However, in such a conventional window display control method for a word processor, a plurality of software are created by forming a soft window area and a hard window area as a window management area in the VRAM. Although it was possible to display a window and one hard window, there were problems as described below.

That is, opening a plurality of soft windows means that the VRA secured as the soft window area.
As long as the memory capacity in M allows, window data can be easily saved in the soft window area in the order in which they were opened, but since the window data is stored by overwriting, the background soft window cannot be displayed. was there.

Further, it is difficult to open a plurality of hard windows due to the limitation of the memory capacity secured as the hard window area and the limitation of display timing.

An object of the present invention is to open a plurality of hard windows to improve the flexibility and usability of window display applications.

[0011]

According to the first aspect of the present invention,
In a window display control method for controlling display of a plurality of windows by storing in the window management memory information about the display position and the display window when the window is displayed at a display position specified on the display, a plurality of windows are displayed on the display.

When deletion of the display window is instructed, it is confirmed whether the window information is stored in the window information save area, and the window information is stored. In this case, the instructed display window is erased and the stored window information is called and displayed.

According to a second aspect of the present invention, a fixed window management area for storing information about a fixed window to be fixedly displayed on the foreground on the display is formed in the window management memory, and the fixed window display is instructed. If there is a fixed window already displayed, the information about the display window is saved in the window information save area, the display of the fixed window is erased, and the designated fixed window is displayed. When the deletion of the fixed window is instructed, it is confirmed whether or not the fixed window information is stored in the fixed window management area. If the fixed window information is stored, the display of the instructed fixed window is deleted. The fixed window information stored as If a fixed window information to the U data saving area is evacuated, it is effective to store the fixed window information to the fixed window management area.

[0013]

According to the first aspect of the present invention, when a window is displayed at a display position designated on the display, information about the display position and the display window is stored in the window management memory so that a plurality of windows can be displayed. In the window display control method for controlling, a window information save area is set in the window management memory for saving information regarding windows that are already displayed when a plurality of windows are displayed on the display, and the window display is instructed. If there is a window that has already been displayed, the information about the display window is saved in the window information save area, the display window is erased, the specified window is displayed, and the deletion of the display window is instructed. If it is, the window information save area will be saved. Check whether the dough information is stored, if the window information is stored, and displays calls the window information stored by erasing the indicated display window.

Therefore, when opening a plurality of windows,
A new window can be displayed without performing an operation of closing the already displayed window, and the operability when using the window can be improved.
