Abstract

PURPOSE:To execute the processing of a window to be most necessary to a user in giving it priority by switching the priority of a process scheduler so as to select a process to plot the contents of the window located above in giving it the priority at the time of changing the superposition of the windows. CONSTITUTION:When a priority switching instructing means 40 instructs a process scheduler 50 to cause the priority of the process corresponding to a window 912 located at the top to be maximum based on the contents of a superposition information area 30, the process scheduler 50 selects the process instructed from a process group 60 in giving it the priority. A plotting request from the selected process is expanded to a graphic image (for example, a circle and a line) by a window contents plotting means 70. A superposition processing means 80 plots the expanded image onto a display 90 based on the information of the superposition information area 30. Thus, the processing speed of the window necessary to the user can be executed in giving it the priority.

Description

[Detailed description of the invention] [Industrial application field] INDUSTRIAL APPLICATION This invention is utilized for the data input of an information processing apparatus.

The present invention is suitable for use in a CAD device.

The present invention is used in a process priority determination method for a multi-window computer.

〔overview〕

In the process priority determination method, the present invention switches the priority of the process scheduler so that when the superimposition of windows is changed, the process that draws the contents of the upper window is selected preferentially. It is designed to give priority to the processing of windows that require it.

[Conventional technology]

Traditionally, process prioritization schemes have been performed independent of the position of window overlap.

[Problem that the invention seeks to solve]

However, in this conventional process priority determination method, the priority of the process is unrelated to the position of the stacked windows, so the processing for the upper window that the user most wants to use is given more processing than the lower window. It had the disadvantage of being slow and difficult to use.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks, and aims to provide a process priority determination method that prioritizes processing of windows that are most needed by the user.

[Means for solving problems]

The present invention provides a process priority determination method, comprising priority switching instruction means for giving a predetermined priority switching instruction to a process scheduler based on the contents of a superimposed information area,
This process entry scheduler is characterized by including means for switching the predetermined priority so as to give priority to the processing of the window displayed above based on the switching instruction.

[Effect]

The priority switching instruction means provides a predetermined priority switching instruction to the process scheduler based on the contents of the superimposed information area. Based on this switching instruction, the process scheduler switches the predetermined priority so that the processing of the window displayed above is prioritized.

As a result of the above, it is possible to preferentially process the window that the user most needs.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. The figure is a block diagram of a process priority determination device according to an embodiment of the present invention. In the figure, the process priority determination device includes a plurality of process groups 60, a process scheduler 50 that selects one of the plurality of process groups 60 based on a predetermined priority, and a drawing request for the selected process. a window content drawing means 70 that develops the image into a drawn image; and a superposition information area 30 that stores window superposition information.
and a keyboard 10 as an input means for inputting instructions to change the window superimposition. Or a mouse 102 and a keyboard 10. Or superposition information changing means 2 for changing the contents of the superposition information area 30 based on the output of the mouse 102
0 and windows 911-91. and a superposition processing means 80 for drawing the output of the window content drawing means 70 on the display device 90 based on the contents of the superposition information area 30.

Here, the feature of the present invention is that the superposition information area 3
priority switching instruction means 40 for giving an instruction for switching the predetermined priority to the process scheduler 50 based on the contents of 0;
The process scheduler 50 includes means for switching the predetermined priority so as to give priority to the processing of the window displayed above based on this switching instruction.

The operation of the process priority determination device having such a configuration will be explained. In the figure, the user has 7x10□ or keyboard 10. When a change in the overlapping position of the windows is specified, the overlapping information changing means 20 changes the overlapping information in the overlapping information area 30. In the figure, the overlay information is stored in window 91. ．． 912.911. If you give an instruction to bring the window 91□ to the top, the order will be 912.913.911.

The priority switching instruction means 40 causes the process scheduler 5 to set the priority of the process corresponding to the topmost window 912 to the highest based on the contents of the superimposition information area 30.
Instruct to 0. The process scheduler 50 preferentially selects the designated process from the process group 60. A drawing request from the selected process is made by the window content drawing means 70 to draw a graphic image (for example, a circle, a line).
will be expanded to. The superposition processing means 80 draws the expanded image on the display device 90 based on the information in the superposition information area 30.

〔Effect of the invention〕

As explained above, the present invention has an excellent effect of increasing the window processing speed required by the user.
