Abstract

PURPOSE:To execute the processing of a window to be most necessary to a user in giving it a priority by selecting a plotting primitive 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:A plotting priority switching means 40 dequeue a plotting primitive 60 in giving it the priority from a plotting primitive queue 50 corresponding to the window judged to be located above by the information of a superposition information area 30, and the primitive 60 is sent to a window contents plotting means 70. The window contents plotting means 70 develops the plotting primitive 60 to a graphic image, for example, a circle, and a line. A superposition processing means 80 plots the developed image onto a display 90 based on the information of the superposition information area 30. Thus, the processing of the window to be most 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 drawing window determination method for a multi-window computer.

〔overview〕

In the drawing window determination method, the present invention prioritizes processing of the window most needed by the user by preferentially selecting a drawing primitive that draws the contents of the upper window when the stacking of windows is changed. It was designed to be carried out in the following manner.

[Conventional technology]

Conventionally, the drawing window determination method has been performed according to the order in which drawing requests are generated (the arrival of drawing primitives), regardless of the overlapping position of the windows [the problem that the invention aims to solve]. In the drawing window determination method, since the window to be drawn is unrelated to the position of the stacked windows, processing for the upper window that the user most wants to use may be slower than for the lower window.
There was a drawback that it was difficult to use.

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

[Means for solving problems]

The present invention provides a window content drawing means for developing a drawing primitive into a drawing image, an overlay information area for storing window overlay information, an input means for inputting a window overlay change instruction, and an output of the input means. an overlay information changing means for changing the contents of the overlay information area based on the overlay information area, a display device, and an overlay process for drawing the output of the window content drawing means on the display device based on the contents of the overlay information area. a drawing primitive queue for inputting a plurality of input drawing primitives, and a drawing primitive cue corresponding to one of the plurality of drawing primitives based on the contents of the superimposition information area; The present invention is characterized by comprising a drawing priority switching means for extracting a drawing primitive from the window and applying it to the window content drawing means.

[Effect]

The drawing limits for each window are enqueued into multiple drawing primitive queues. The drawing priority switching means extracts a drawing primitive from a corresponding one of the plurality of drawing primitive queues based on the contents of the superimposition information area and supplies it to the window content drawing means.

Through the above operations, processing of the window that is most needed by the user can be performed preferentially.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. The figure is a block diagram of a drawing window determining device according to an embodiment of the present invention. In the figure, the drawing window determination device includes a window content drawing means 70 for developing drawing primitives into a drawing image, an overlay information area 30 for storing window overlay information, and an input means for inputting window overlay change instructions. Keyboard 10. Alternatively, the mouse 10 □, the superimposition information changing means 20 that changes the contents of the superposition information area 30 based on the output of the keyboard 101 or the mouse 102, the display device 90 that displays the window weight, ~913, and the window content drawing A superposition processing means 80 is provided for drawing the output of the 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 a plurality of input drawing primitives 60. Drawing primitive queues 50 and -503 into which . . . This is because a switching means 40 is provided.

The operation of the drawing window determining device having such a configuration will be explained. In the figure, a user can use a mouse 102 or a 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 window 912.912.911
It becomes. When an instruction is given to bring the window 912 to the top, the order becomes 912.913.91.

To draw to each window, the user program must:
The drawing primitives 101 to 103 are enqueued to the drawing primitive keys: L-50, to 503 for each window. Drawing primitives 601 to 603 are a group of commands such as "draw a circle" and "draw a line".

The drawing priority switching means 40 preferentially sends the drawing primitive 60 from the drawing primitive queue 50 corresponding to the window determined to be located above according to the information in the superposition information area 30 to the display and window content drawing means 70. The window content drawing means 70 develops the drawing primitive 60 into a graphic image (for example, a circle, a line).

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.
