FIG. 16 is a flowchart showing the operation when a new window is created. In step S1, creation of a window is instructed, the window is displayed at a specified position, and the area of the displayed window is calculated. In step S2, the distance from the center point of the display screen to the center point of the created window is calculated.
In step S3, the order of the windows in the Z direction is calculated. In step S4, the data obtained in steps S1 to S3 is added to the window management table 19,
It is stored in association with the window number 33.

FIG. 17 is a flowchart showing the operation when the position in the plane of the window, the area, and the order in the Z direction are changed. In step S11, a change is instructed, the designated window is displayed again under the changed condition, and the area of the window is calculated. Step S12
In, the distance from the center point of the display screen to the center point of the redisplayed window is calculated. In step S13,
The rank of the window in the Z direction is calculated. Step S
At 14, the data obtained in steps S11 to S13 is updated and stored in the window management table 19.

FIG. 18 is a flowchart showing the task switching processing operation. The flowchart shows an operation when task processing is allocated at a predetermined time, that is, a so-called timer interrupt operation. In step S21, the CP
The various information of U12 is saved, and the number of the task being executed is read. In step S22, the highest priority window is selected from the window management table 19, and the window position information 35 of the selected window is read. In step S23, a pointer is set at the position of the read window position information 35. In step S24, it is determined whether the window pointed to by the pointer is the window of the task being executed. If the determination is affirmative, the process proceeds to step S25, and if the determination is negative, the process proceeds to step S26.

In step S25, the pointer is updated, and the flow returns to step S24. In step S26, window information of the window pointed by the pointer, that is,
The data stored in the buffer 17 is read. Step S
At 27, various information of the CPU 12 is set so that the task of the read window can be executed. Step S
At 28, the CPU 12 is allocated and operated for the read window.

Thus, for example, when a window with a high priority is occupied, the first priority is set for windows W11, W12, and W13, and the second priority is set for window W14. In the case, FIG.
As shown in (A), when the processing time of the CPU 12 is divided into three and used, and when all the windows W11 to W13 become idle time, the processing time of the CPU 12 is allocated to the window W14.

In the case where the processing time of the CPU 12 is divided at a predetermined ratio, the first priority is
In the case where the first priority is set to 11, W12, and W13 and the second priority is set to the window W14, the first priority is larger than the second priority, for example, three times as shown in FIG. 19B. Processing time is allocated.

FIG. 20 is a diagram showing a display screen 38d of the multi-window display processing device according to the fourth embodiment of the present invention. The display processing device of the present embodiment is realized in the same manner as the display processing device of the first embodiment except that the priority setting method is different. In this embodiment, the priority is directly input and set by the operator.

A plurality of windows W are displayed on the display screen 38d.
21 to W23 are displayed. Windows W21 to W23
Have a title bar area 51 and a display area 52. The title bar area 51 is a window identification information display area 5 where information for identifying a window is displayed.
3, a priority display area 54 in which the priority is displayed, and an occupancy display area 55 in which the occupancy is displayed.

For example, the operator gives an instruction by clicking on a position in the priority display area 54 using a mouse or the like of the input unit 21. Thus, numerical values can be input, and the operator inputs numerical values from the keyboard of the input unit 21 to set the priority.

FIG. 21 is a diagram showing a window management table 19d according to the fourth embodiment. The window management table 19d includes at least the priority information 34. In the present embodiment, the Z direction information 37, the distance information 43, and the area information 4

Allocates the processing time of the task requested from each of the windows W21 to W23 in a time-sharing manner according to the priority set as described above.

FIG. 22 is a flowchart showing the operation of the multi-window display processing device of the fourth embodiment. In step S31, a click operation with the mouse is detected, and when the click operation is detected, the position where the click operation is performed is detected in step S32. If no click operation is detected in step S31, the process ends.

In step S33, it is determined whether the detected position is within the priority setting area, that is, within the priority display area 54. If it is determined that it is within the priority display area 54, the process proceeds to step S34, and waits for a numerical value to be input. If it is determined that it is not within the priority display area 54, the process is terminated.

In step S35, it is determined whether a numerical value has been input. If it is determined that the numerical value has been input, the flow advances to step S36 to update and store the priority. If it is determined that no input has been made, the process ends.

Therefore, multitask processing can be executed with high utilization efficiency. Further, the processing time is allocated based on the priority set by the operator. Therefore, it is possible to execute the processing in the order desired by the operator. In addition, since the input priority is displayed, the operator can easily set the priority while checking it visually.
