Furthermore, the selected graphic is stored in the selection graphic storage part 8, A feasible menu can be selected by discriminating the kind of the selected graphic stored in the selection graphic storage part 8. referring to the selection graphic storage part 8, and referring to a menu table by a menu selection means 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic editing system using a computer.

[0002]

2. Description of the Related Art In a system for editing graphics such as CAD, a menu showing processing contents prepared in advance is used. The user can create or edit a desired figure by selecting a menu according to the processing content.

As the system becomes more sophisticated, the number of types of processing is increasing, and the total number of menus is becoming enormous. Therefore, the menus are hierarchically classified according to the processing content.

[0004]

In the conventional menu system, a menu other than the one intended by the user is displayed at the same time, and it may be unclear in which category the intended menu is included. , There was a problem that the user had to find the necessary menu.

Since the type of graphics to be processed differs depending on the menu, the user has to remember the type of graphics to be processed along with the processing content of the menu or read the instruction displayed on the screen. There was a problem of reduced efficiency.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a menu system which enables easy operation.

[0007]

According to the present invention, in a menu display system, a display means for displaying characters and figures, a means for storing / editing figures, and a figure to be edited are selected from the displayed figures. Means, a means for determining the type of graphic selected by the means, and a menu management means for selecting and displaying an executable menu item for the type of graphic to be processed, which is determined by the means. It is characterized by having.

[0008]

The present invention is constituted by the above-mentioned means, and by selecting a figure to be processed, the menu is classified according to the kind of the figure to be selected in advance according to the kind of the figure to be processed. A menu to be displayed is displayed, and the user selects a desired menu from among them.

FIG. 1 is a diagram showing the configuration of a graphic processing system according to an embodiment of the present invention. In FIG. 1, 1 is a computer system, 2 and 3 are a display device and a position input device which are respectively connected to the computer system 1, and 4 is a position detecting means for calculating a position indicated by the position input device 3,
Reference numeral 5 is cursor display means for displaying a cursor on the display device 2 at the coordinates obtained by the position detection means 4, 6 is a graphic information storage section for storing attributes and coordinates of a graphic, and 7 is stored in the graphic information storage section 6. Display device 2
The figure display means for displaying the figure, 8 is a selected figure storage section for storing the figure instructed by the position detection section 4 by referring to the figure information storage section 6, and 9 is an executable menu by referring to the selected figure storage section 8. Is a menu selection means for obtaining a menu instructed from the position detection means 4 and the menu display means 9, and is provided with a menu table classified by the type of element to be processed.
Reference numeral 11 is a graphic processing means for performing processing corresponding to the contents of the menu instructed by the menu selecting means 10 and updating the graphic information stored in the graphic information storage section 6.

FIG. 2 is a diagram showing the flow of a menu-based process for displaying a menu that can be executed according to the type of the selected figure in the embodiment of the present invention.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The coordinate data N acquired by the position detecting means 4 is input in step 1. In step 2, it is determined whether the coordinate data N is on the always usable menu, and if it is on the always usable menu, the process according to the menu is performed in step 3 and the process returns to step 1. If it is not on the menu that can always be used at step 2, it is determined whether it is on the menu at step 4, and if it is on the menu, the process according to the menu is performed at step 5 and step 6
Then, the graphic information stored in the selected graphic storage unit 8 is initialized and the process ends. If it is not on the menu in step 4, the graphic information storage unit 6 is referred to in step 7 to acquire the graphic information, or the coordinates if there is no graphic at the position indicated by the coordinate data N. In step 8, the selected figure is stored in the selected figure storage unit 8. In step 9, the type of the selected graphic stored in the selected graphic storage unit 8 is discriminated, and in step 10, the selected graphic storage unit 8 is referenced and the menu table in the menu selection means 10 is referenced to select an executable menu. . FIG. 3 shows a flowchart of the processing at this time.

At step N1, variables for counting the types of elements are initialized. In steps N2 to N6, the type of the selected element stored in the selected figure storage unit is counted. In this example, a straight line and an infinite line, and a circle and a circular arc are treated as elements that can perform the same processing. In step N7, the number of element types selected is determined, and in step N8, the classification number of the menu is acquired. In this example, np is 1 or 0 when 1 point is selected, nl is 2 or 1 when 1 straight line or infinite line is selected, and nc is 1 or 1 circle. Or when one arc is selected, the second, nl
+ Nc = 2 In other words, if there are two straight lines or one straight line and one circle or two circles, then number 3 is obtained. The menu having the classification number of the menu thus obtained is displayed.

The menu table is created in advance according to the classification of the menus obtained here. And st
At ep11, the menu display means 9 displays the menu on the display device 2.

4 to 6 are views showing a concrete embodiment of the present invention. In the figure, 12 is a drawing area for displaying a graphic, 13 is a menu, 14 is a cursor, and 15 is an input graphic.

FIG. 4 shows a state before selecting a graphic element. In this state, the menu corresponding to the selected graphic type is not displayed, but the menu that can be selected at all times is displayed. Menus that can be selected at all times include menus that do not target specific graphics such as file operations and display enlargement / reduction. Further, like the conventional menu, a menu for designating the process first and then instructing the target graphic is also displayed, and the menu system according to the present invention can be used together.

FIG. 5 shows a state in which the graphic element 11 is selected. An executable menu is displayed according to the type of the selected figure. In this example, l1 is a straight line, so that a menu for which one straight line is the target of processing is displayed. The display position of the menu is automatically determined and can be displayed at a fixed position.

FIG. 6 shows a state in which the graphic element c1 is further selected. A menu different from that shown in FIG. 5 is displayed which can be executed depending on the combination of the selected graphic types. In this example, since l1 is a straight line and c1 is a circle, a menu in which one straight line and one circle are the processing targets is displayed.

[0019]

According to the present invention, since only executable menus are displayed for the selected figure, it is possible to construct a system that does not impair operability even if the total number of menus becomes enormous. . Further, since it can be used together with the conventional menu system, it is possible to selectively use the conventional menu system and the menu system of the present invention depending on the processing content.
