Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window display processing method for displaying an output of a computer on a display device by providing a window on the display screen and displaying the output of each application program in each window. .

[0002]

2. Description of the Related Art When displaying the output of a computer on a display device, it is well known to provide a display section called a window on the display screen and display the output of each application program which is different for each window.

In such a system, even if each application program is configured to output the entire screen of a dedicated display device without considering output display to a window, for example. , There is a method of providing a virtual terminal device to enable output to a window.

That is, the virtual terminal device provides the application program with an output interface to the terminal device originally intended by the program, receives information output by the application program for display, and displays it on the display screen. The output information is converted so as to be displayed in the corresponding window and is output to the display device.

FIG. 3 is a block diagram showing an example of the configuration of the above system. Application programs 8a, 8b, 8c (referred to as application programs A, B, C) are executed by the data processing device 9 and their outputs are output. When outputting to the display device 12, a window for each application program is displayed on the display screen of the display device.
13a, 13b, and 13c (windows A, B, and C) are provided and displayed.

In this case, each application program A, B, C
Corresponding to the above, virtual terminal devices 1a, 1b, 1c (referred to as virtual terminal devices A, B, and C) for the purpose of the above-described functions are provided, and the information output by each virtual terminal device is displayed in the window system 10. After that, display in each window.

The position and size of each window are specified by the user at the time of starting each virtual terminal device by input means such as the keyboard 14 and the mouse 15, and are held in the virtual terminal device and the window system 10. Referenced in controlling the display. Also, the user can change the designation of the window by requesting the window manager 7 even during execution.

FIG. 4 is a block diagram showing a configuration example of the virtual terminal device, and the virtual terminal device 1 is a window system.
The input of the user is transmitted to the application program 8 by the input processing unit 2 via 10 and the output from the application program 8 is received by the output processing unit 3 and passed to the display processing unit 5.

The display processing unit 5 refers to the size of the window stored in the management information storage unit 6, converts it into information for window display, and requests the window system 10 for output.
As the size of the window held in the management information storage unit 6, the value designated when the virtual terminal device 1 is started is held, and then changed by the user's designation through the window manager 7 as described above. In response to an inquiry from the application program 8, the size of the window to be held is answered, so that each application program creates an output for display on a screen of such size.

[0010]

In the system as described above, the size of the window can be specified by the user and changed. However, in order to display a plurality of windows in an easy-to-see manner, the size and position of each window can be changed. Must be adjusted appropriately.

However, the amount of display characters or the like output by each application program at each point of time is often unknown in advance, and if there is a large variation even if it is known, it is adjusted according to the case where the display amount is large. It is difficult to make proper adjustments.

An object of the present invention is to provide a window display processing method for automatically adjusting the size of a window according to the display amount.

[0013]

FIG. 1 is a flow chart of processing showing the configuration of the present invention. The figure shows the configuration of the window display processing method, in which the output of the application program is output to the window provided on the display screen of the display device corresponding to the virtual terminal device via the virtual terminal device to which the application program is connected. When displaying, the virtual terminal device performs processing steps
For each output received at 20, process step 21 estimates the size of the display area required to display the output.

Next, in processing step 22, the size of the window is set to a size determined by the estimated size. In step 23, the output is displayed in the set window.

[0015]

According to the processing method of the virtual terminal device of the present invention, the size of the window is automatically expanded / contracted according to the display amount of each output, so that a window of a size that is easy to see always occupies a wasteful area. It will be set without any more, and the operability of the user who works by using the window can be improved.

[0016]

FIG. 2 shows an example of the configuration of a virtual terminal device 31 for executing the processing method of the present invention. The virtual terminal device is arranged between the application program and the window system as in the conventional case.

The virtual terminal device 31 transmits the user's input to the application program 8 by the input processing unit 2 and receives the output from the application program 8 by the output processing unit 33 via the window system 10 as in the prior art. To the display processing unit 35.

Here, the output processing unit 33 also passes the output from the application program 8 to the display control unit 34, and the display control unit 34 is shown in FIG.
The processing of step 21 is executed to estimate the size required as a display area from the output amount.

That is, for example, the height of the display area is determined by the number of output lines, and the width of the display area is determined by the maximum number of characters in those lines. Next, the display control unit 34 executes the processing of processing step 22 in FIG. 1 to specify the window size for displaying the height and width estimated in processing step 21, for example, and set the window. , And requests the window system 10 to notify the size of the display processing unit 35 at the same time.

The display processing unit 5 executes the processing of processing step 23 in FIG. 1, converts the output of the application program into window display information according to the notified window size, and outputs it to the window system 10. To request.

The management information storage unit 36 holds the window size in the same manner as the conventional management information storage unit 6,
Further, the size to be held can be changed by the user's designation, and the size of the window to be held can be answered in response to the inquiry from the application program 8.

However, since the size held in the management information storage unit 36 is not referred to in the processing of the display processing unit 35, it is a virtual size, and for example, the maximum size that the user thinks is necessary is set. Keep it.

This virtual size is used by the application program 8 to perform processing as if it were output on a screen of such size, but the actual window size is as described above. It is changed to the optimum size according to the output display amount for each.

FIG. 5 is a diagram for explaining the display of a window according to the present invention. Even if windows A, B and C are displayed with a size as shown in FIG. When the output of each application program increases with respect to windows A and C and decreases with respect to window B, it is changed to the window illustrated in (b).

[0025]

As is apparent from the above description, according to the present invention, in the process of displaying the output of the computer on the display device, the size of the window is automatically adjusted according to the display amount, so that it is always easy to see. A window of a size can be set without occupying a useless area, which has a remarkable industrial effect of improving the operability of a user who works by using the window.
