Abstract

PURPOSE:To quickly and easily execute a picture drawing operation by operating a mouse in a position where the present picture drawing processing is being executed. CONSTITUTION:An operator moves a mouse 2 in the X and Y directions, while depressing a key, moves a cursor 16 on a screen 22, and moves the cursor 16 to a desired command display position of a command menu on the screen 22. Its rectangular part is inverted by an operation of a bit map inversion unit 18, and when the key is set free at its position, a command which is indicated by the cursor 16 in the command menu is selected, and the command menu is erased from the screen 22.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for displaying a command menu in a display device of a computer-aided drafting system, or CAD.

[Conventional technology]

In this type of device, a method is known in which a command menu is set in an off-screen area, as disclosed in, for example, Japanese Unexamined Patent Publication No. 60-7577.

Furthermore, a method is known in which a command menu is always displayed at the end of the drawing area on the display screen.

[Problem that the invention seeks to solve]

In the first method, the command menu is located in an off-screen area, so the command menu is not displayed on the screen. As a result, there was a drawback of poor operability.

Furthermore, the second method has a drawback in that one drawing area becomes smaller because the command menu is always displayed on the screen.

In the present invention, when a command menu is required during drawing,
The purpose of this method is to temporarily display a command menu in the drawing area by operating the mouse, thereby eliminating the above-mentioned defects.

[Means to solve problems]

In order to achieve the above objects, the present invention provides a method for displaying a command menu on the screen, in which when the mouse is moved by a small amount in the XY direction while pressing a key on the mouse, the command menu corresponding to the direction of movement of the mouse is displayed. The command menu is displayed on the screen and disappears from the screen when the key is released.

〔Example〕

The structure of the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

In FIG. 3, reference numeral 2 denotes a well-known mouse that outputs an X-Y coordinate signal, and is connected to a cursor control 4. 6 is a menu processor.

This is the part that receives commands from the command menu and controls the commands to process each function. Reference numeral 8 denotes a command processing section, which receives commands of menu codes selected from the command menu and actually executes processing for the commands. Reference numeral 10 denotes a menu drawing unit, which constitutes a control section for displaying a command menu. Reference numeral 12 denotes a cursor drawing unit, and this unit and the cursor control 4 constitute a control portion for moving the cursor 16 on the screen bitmap 14'' using the mouse 2. Reference numeral 18 denotes a bitmap inversion unit, which constitutes a control portion for inverting the rectangular coordinates and rectangular area in the command menu. 20 is a bitmap transfer unit which, when a command menu is displayed on the screen 22, temporarily stores bitmap data, that is, figure data corresponding to the command menu area in the memory bitmap 24, and then displays the command menu. This is to restore the previously stored bitmap data after the completion of the process.

Next, the operation of this embodiment will be explained.

The operator selects the left key 26 of the two keys on the mouse 2, and presses the mouse 2 while holding down the key 26.
When the key 26 signal and the +ΔX output coordinate signal of the mouse 2 are moved by a minute amount ΔX in the +X coordinate direction, the key 26 signal and the +ΔX output coordinate signal of the mouse 2 are supplied to the menu processor 6, and the processor 6 gives a command to the menu drawing unit ]-0 to draw the screen bit map. 14
Window command menu 30 on top cursor 16
and the menu 30 is displayed on the screen 22.

Also, if you move the mouse 2 by a small amount in the +Y force direction while pressing the left key 26, the point command menu 32 will be displayed on the cursor 16 on the screen 22, and while pressing the left key 26, you can move the mouse 2 by -Y. When the force direction is moved by a small amount, a screen operation command menu 34 is displayed on the cursor 16 on the screen 22. Operator presses key 2 on the right
When the mouse 2 is moved by a small amount in the -X direction while pressing 8, a user command menu 36 is displayed on the cursor on the screen 22. Further, when the right key 28 is pressed and the mouse 2 is moved by a small amount in the +Y force direction, the building 1 to in-command menu 38 are displayed above the cursor ]6 on the screen 22. Further, when the mouse 21 is moved by a small amount in the -Y force direction while pressing the right key 28, a transient command menu 4o is displayed on the cursor 16 on the screen 22. The operator moves the mouse 2 in the X and Y directions while pressing the key to move the cursor 16 on the screen 22.

When the cursor 16 is moved to a desired command display position in the command menu on the screen 22, the rectangular part thereof is inverted by the operation of the bitmap inversion unit 18, and when the key 26 or 28 is released at that position, the command menu is displayed in the command menu.
The command indicated by the cursor 16 is selected and the command menu is deleted from the screen 22. Note that when selecting the command menu, if the mouse 2 is moved over a predetermined distance while pressing the key 26 or 28 of the mouse 2, the display of the command menu disappears from the screen 22 and the screen returns to the creation screen.

The above window command is a command for operating the window on one screen 22, the above point command is a command for picking up points from a drawing, the above drawing operation command is a command for operating a drawing, and the above user command is a command for operating a drawing. These are commands for the user, and the above built-in commands are commands for creating drawings. This built-in command has a hierarchical command system.

Therefore, if you want to call up a command from another system, you should do so after returning to the first main menu. The transient command is a command for efficiently creating drawings, and is an interrupt command call for the built-in command.Basically, the command system is not hierarchical, and there are few types of command calls. In FIG. 4, a screen operation command menu 34 is displayed on the screen 22. In this menu, the rectangular area E where the cursor 16 is located is the bitmap inversion unit 18.
has been reversed by In the above drawing operation command menu 34, RDW is redrawing, 2MIN is enlarged screen display, 1x is viewpoint movement, 2X is double zoom, D/FV
is the full display of only the graphical elements, A/FV is the full display of the graphical elements, Z
MOT is a reduced view of the drawing, 1/2X is a 1x2x zoom,
DPLT means drawing plotter output.

〔effect〕

As described above, the present invention does not require you to move the cursor to a specific position on the display screen in order to call up the command menu, but simply operates the mouse at the position where the current drawing process is being performed. is displayed and commands can be selected from this menu, which has the effect of making it possible to perform drawing operations quickly and easily.
