Abstract

PURPOSE:To obtain the graphic processor capable of immediately detecting a command being misselected by altering the shape of a mouse cursor corresponding to a command selected in a command menu displayed on a display device. CONSTITUTION:This graphic processor is provided with a central processing unit 103, a storage device 107, a display device 101, a mouse device 106, and a keyboard 104. When a designer starts designing and makes a selection of the command menu, the shape of the cursor is altered corresponding to the selected command. For example, when a 'circle' command in the command menu 102 is selected, the cursor is changed into a circular one, the shape of which is unchanged until another command is selected thereafter. Thus, what command is currently selected can always be recognized during operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic processing device such as CAD.

[0002]

2. Description of the Related Art In recent years, graphic processing devices using computers have been widely used. In particular, there is a remarkable use of CAD in which a computer assists drafting in mechanical design. When CAD is used for conventional mechanical design, various commands must be selected from a command menu. In a typical graphics processing device, many commands are displayed on the screen in the form of a command menu.
Often, I accidentally select a command adjacent to the command I want to select. A conventional graphic processing device will be described below with reference to the drawings.

FIG. 6 is a schematic diagram showing a case where a "circle" command is selected from the command menu 102 in the conventional graphic processing apparatus, and graphic elements such as straight lines and circles and characters are displayed. Drawing area 100 and command menu display area 10 for displaying a command menu
2, a display device 101 for displaying the whole view and a mouse cursor 105 are shown.

FIG. 7 is a diagram showing a case where a "circle" command is selected from the command menu 102 in the conventional graphic processing device and a "straight line" command is erroneously selected and drawn. A drawing area 100 for displaying graphic elements and characters such as circles and circles, a command menu display area 102 for displaying a command menu, a display device 101 for displaying an overall view, and a mouse cursor 105 are shown.

In FIG. 6, when the designer wants to select the command "circle", he may mistakenly select "straight line". At this time, the designer does not notice that he has mistakenly selected the command "straight line", and performs drawing in the work area 100 as shown in FIG. 7 to learn that he has mistakenly selected the command.

[0006]

However, in the above-mentioned conventional method of selecting a command in the graphic processing apparatus, when the designer selects a command different from the desired command, the graphic is not noticed unless the graphic is drawn. Then you have to select the command from the command menu again. Therefore, there is a problem that the work is interrupted and the work efficiency is reduced.

The present invention solves the above problems, and an object of the present invention is to provide a graphic processing device capable of immediately detecting a command selection error.

[0008]

In order to achieve the above-mentioned object, the present invention has a structure including means for changing the shape of a mouse cursor according to a selected command.

[0009]

The present invention can detect a command selection error by the above-mentioned configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a graphic processing apparatus according to the present invention. A drawing area 100 for displaying graphic elements such as straight lines and circles and characters, a command menu display area 102 for displaying a command menu, and a display device 101 for displaying an overall view.
And a keyboard 104 for inputting characters and numerical values, a central processing unit 103 for controlling them, and a storage unit 107 for storing characters and figures. The graphic elements of the drawing area 100 and the command menu display area 102 are provided. The above command menu is designated by the mouse device 106 to edit the graphic element.

FIG. 2 is a functional block diagram of the device according to the present invention. A central processing unit 103, a storage unit 107,
Display device 101, mouse device 106, and keyboard 10
4 is equipped.

The operation of the embodiment will be described with reference to the flow chart of FIG. 5 and FIGS. 3 and 4 are
FIG. 3 is a diagram illustrating a display example, including a drawing area 100 for displaying graphic elements such as straight lines and circles and characters, and a command menu display area 102 for displaying a command menu.
Display device 101 and mouse cursor 10 for displaying the overall view
5 is shown. The lower row shows the shape of the mouse cursor after selecting a command. The numbers in parentheses indicate the processing steps in FIG. When the designer starts designing (200) and the command menu is selected (2
01), change the shape of the cursor according to the selected command. For example, when the "circle" command in the command menu 102 in FIG. 3 is selected, the cursor changes to a circular shape as shown in the lower part of FIG. Thereafter, the shape of the cursor does not change until another command is selected (203). In addition, the designer, as shown in Figure 4, "curve"
When you select the command, the cursor that was in the shape of a circle
As shown in the lower part of FIG. 4, the shape changes to a curved line.

As described above, according to the graphic processing apparatus of the embodiment of the present invention, it is possible to always confirm what the currently selected command is during the operation.

[0014]

As is apparent from the above embodiments, according to the present invention, it is possible to visually inform the designer what the command selected in the command menu is. It is possible to quickly notice mistakes and provide a graphic processing device with good work efficiency.
