Abstract

PURPOSE:To enable an operator to easily recognize an input waiting state by using a means which detects a window set under an input waiting state out of plural windows. CONSTITUTION:The data stored in a memory 32 are transferred to a VRAM 33 by an instruction of the program to be executed by a CPU 31 and then displayed on a CRT 34. The positions, the sizes and the display information of the windows A-C to be displayed are stored in the areas AA-CC of the memory 32. The CPU 31 checks a program instruction to be executed to decide whether a program under operation is set under a key input waiting state or not. Then it is checked for the program set under a key input waiting state is superposed whether the relevant window is superposed on another window or not. If so, the information on the superposed areas are read out of the memory 32 and the information on an area of the VRAM 33 corresponding to said superposed areas is changed for change of the luminance of a display screen.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multi-window display method in a display device. - [Prior Art] In general, a multi-window method has been proposed in which when multiple application programs called multi-process are executed, input/output information for each program operation is displayed in multiple windows in correspondence with each program. There is.

Conventionally, in this type of system, as shown in Figure 3, window A, which displays the manual input information of the first program, is displayed first, and then window B, which displays the input/output information of the second program, overlaps window A. will be displayed.

In this state, even if the program running in Window A is waiting for human power, it is hidden in Window B, so the operator does not know that the second program is waiting for human power, and the efficient operator selects Window B. window B cannot be displayed in front of the screen. Therefore, there is a drawback that the operator cannot perform efficient operations.

In addition, in order to prevent windows B and A from overlapping, the size of window B is limited due to screen size constraints, which limits the size of characters on the display screen, which has the disadvantage of making it difficult to see in terms of operation. .

(Problems to be Solved by the Invention) Therefore, an object of the present invention has been made in view of the above-mentioned drawbacks of the conventional example. To provide a multi-window display system that can notify an operator that there is a window waiting for input.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a multi-window system in which input/output information is displayed on a display means in the form of a plurality of windows. a detection means for detecting a window that is
The present invention is characterized by comprising an extracting means for extracting a portion where the detected window overlaps with another window on the display means.

[Effect]

The present invention extracts the portion where the input waiting window detected by the detection means overlaps with another window, so that it is possible to display this portion in an identifiable manner.

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of an embodiment of the present invention. In FIG. 1, the processing is executed by a calculation processing unit (CPU) 31.

Memory 32 has memory areas AA%BB and CO. The memory area island stores the position of window A to be displayed, the size of the window, and information to be displayed in the display area within window A.

The memory area BB stores the position of window B to be displayed, the size of the window, and information to be displayed in the display area within window B.

The memory area CC stores information on the position and size of the area where windows A and B shown in FIG. 3 overlap.

35 is a key manual device for manually inputting information, and 36 is a program memory for storing programs corresponding to various windows.

Next, the operation in the embodiment of the present invention will be explained with reference to the flowchart shown in FIG.

Note that this control procedure is an interrupt control procedure that is executed when the program is waiting for human input, for example, when there is no input or output for a certain period of time, and this control procedure is stored in the memory 36.
Executed by CPII31.

In FIG. 2, in step S1, the operating status of the program in each window is checked. Next, in step S2, it is checked whether there is a program waiting for key input, and if it is not waiting for input, the process advances to step S6. In step S6, it is checked whether the status of all programs has been checked, and if the checking is completed, this control procedure is ended.

The operating state of the program can be determined by checking the program memory address instructed by the CPU 31 to determine which program is being executed. Further, whether or not the key is waiting for human power can be determined by checking the program command that the CPt 131 is about to execute.

If the CPU 31 is waiting for an input in step S2, the process advances to step S3 to check whether the window waiting for input overlaps with another window. This check is performed as follows.

For example, in the display example of FIG. 3, when the window display frame X is displayed on the display device 34, its image data is stored in the VRAM 33. Therefore, for example, when window B is waiting for human power and the VRAM 33 has data for display frame X, it can be determined that window B is not overlapping.

Further, when there is no data for display frame X, it can be determined that window B overlaps window A. After the determination is made in this manner, if the windows waiting for input do not overlap, the process advances to step S6. If the window is heavy, step S
4, and reads the information of the overlapped area from the memory area CC.

In step S5, the brightness of the display screen is changed to display information on the heel AM area corresponding to the overlapped area.

This change in brightness can be easily realized, for example, in a display device using cathode tubes, by controlling the output to the cathode tubes. Note that the -varied brightness can be returned to the normal brightness when the operator selects a hidden window.

Further, in step S5, the color information of the overlapping area may be set to different color information from the window color information. Furthermore, if the display control means (not shown) outputs the image data of the overlapping area of the window area at predetermined intervals, this overlapping area can be displayed in a blinking manner.

〔Effect of the invention〕

As explained above, according to the present invention, the area of overlapping windows can be identified, so the operator can immediately recognize the input waiting state even if the window is waiting for input but is hidden and cannot be seen. Effects can be obtained.
