Further, as in the conventional case, a plotter, a tablet, a fixed disk device, a magnetic tape device, a printer, a color hard copy device, etc. are optionally connected to the basic device 20 as required, but they are omitted here. .

14 is different from the conventional graphic processing device shown in FIG. 14 in that the software structure in the basic device 20 and the display screen of the display device 30 are indicated by a cursor (to be described later) in the graphic processing device 1a. The point is that a cursor navigation information display area 30c showing the contents is provided.

FIG. 2 shows the internal structure of the basic device 20.
In FIG. 2, reference numeral 201 denotes an operation / comprising a CPU, etc.
A control unit, 202 is a program memory in which the system programs of the arithmetic / control unit 201 are stored, 203 is a data memory, 204 is a position coordinate control unit that controls the position coordinates of figures and cursors on the screen, and 205 is a display. A display control unit to which the device 30 is connected, 206 is a mouse control unit to which the mouse 5 is connected, 207 is a keyboard control unit to which the keyboard 4 is connected, 210 is a memory unit in which various tables to be described later are stored, and 208
Is an internal bus that connects them to each other.

In the memory unit 210, 211 is a syntax table, 212 is a coordinate constraint condition table, 213 is an element constraint condition table, 214 is a coordinate input method priority condition table, and 215 is an element input method priority condition table. A table 216 is a user constraint table. Details of these will be described later.

The display device 30 constitutes a display device, the mouse 5 and the keyboard 4 constitute input means, and the arithmetic / processing section 201 and the program memory 2 are included.
02 constitutes an arithmetic processing means, the cursor navigation information display area 30c shown in FIG. 1 constitutes a cursor navigation information display area, and the tables 211 to 216 in the memory section 210 constitute limiting condition storage means.

When a specific point on the screen, a specific point on a graphic element, and a graphic element are designated by a cursor, there are two input methods, coordinate input and element input. Input coordinates
It specifies a specific point or a specific point on a graphic element based on the coordinates of the cursor. The element input specifies only the graphic element.

The sensing range of the graphic element of the cursor depends on the size of the cursor. That is, if there is an element under the cursor as shown in FIG. 3A, this is detected, and if there is no element under the cursor as shown in FIG. 3B, it is not detected.

A plurality of graphic elements may exist under the cursor. In this case, the coordinate input method priority order condition table 214 and the element input method priority order condition table 215 in the memory unit 210 are displayed. The display priority is determined based on the stored conditions.

In the case of inputting coordinates, for example, as shown in FIG. 4 in the priority condition table 214 of the coordinate input method, a: arbitrary coordinates, b: intersection, c: end point, d: center point ...・ If the priority order is defined in the order of, the display priority order is determined accordingly. Similarly for element input,
The priority order condition table 215 of the element input method defines the priority order in the order of dots, lines, circles, ellipses, etc., and the display priority order is determined according to this.

The relationship between the position of the cursor and the display of the cursor navigation information display area 30c in the case of inputting coordinates will be described with reference to FIGS. FIG. 5 shows the relationship between the cursor C and the graphic on the display screen, and FIG. 6 shows a display example of the display area 30c at that time. In the display area 30c, 31 is an element display frame showing graphic elements such as lines and circles.
Reference numeral 2 denotes a coordinate display frame showing a specific point such as a designated point, an intersection, an end point, or a specific point on a graphic element.

As shown in FIG. 5A, if the cursor C is in a position not particularly related to any figure element, the point designated by the cursor C becomes the designated coordinate P, and the display area 30c is displayed as shown in FIG. As shown in (a) of the above, since the element display frame 31 does not have such an equal element, "-" (hyphen), and the coordinate display frame 32 becomes a "finger" indicating the designated coordinate.

As shown in b), the element display frame 31 is a "line", and the coordinate display frame 32 is an "end" indicating an end. Further, as shown in FIG. 5C, if the cursor C is within the predetermined range of the center point on the line,
Since the center point ML of the line has been designated, as shown in FIG. 6C, the element display frame 31 is “line” and the coordinate display frame 32.
Is "medium" indicating the center point.

In addition, when the circle is prioritized over the line in the priority order of the graphic element or the circle is defined by the element constraint condition for limiting the graphic element specified by the cursor described later, the cursor C Is at the position of (d) in FIG. In this case, if the intersection is prioritized in the priority condition table 214 of the coordinate input method, the intersection CL of the line and the circle is specified, and the display area 30c is displayed in the circle as shown in (d) of FIG. If the center point is prioritized, it will be "circle""middle" indicating the center point MC of the circle.

In FIG. 5 (d), the line is prioritized over the circle in the priority of the graphic element, or the line is defined by the element constraint condition for limiting the graphic element designated by the cursor described later. If so, the display in the display area 30c is "line""intersection" indicating the intersection of the lines and "line""middle" indicating the center point of the lines.

When the cursor C is located at the position (e) in FIG. 5, the coordinate input method priority condition table 214
If the end point is prioritized in, the end point E of the circle is designated, and the display area 30c becomes “circle” “end” indicating the end point of the circle as shown in FIG. If done,
It becomes "circle" or "medium" indicating the center point MC of the circle.

Next, the syntax table 211, the coordinate constraint condition table 212 and the element constraint condition table 213 of the memory unit 210 of FIG. 2 will be described. In the syntax table 211, moving, rotating, erasing,
Stores various definitions related to the input order and input method defined for each command (function) such as drawing a straight line.
In this, the input method of coordinate input or element input is stored. And FIG.
For example, if a command ID “MOVE” is input as shown in, information corresponding to this, for example, 311 is retrieved, and the input method for the current parameter is neither coordinate input nor element input. The user is informed whether or not it is displayed on the screen.

Further, a constraint condition is retrieved from various definitions on the syntax table 211 corresponding to the input command and stored in the coordinate constraint condition table 212 and the element constraint condition table 213. That is, in the coordinate constraint condition table 212 and the element constraint condition table 213, the coordinates designated by the cursor corresponding to the command,
A coordinate constraint condition and an element constraint condition that limit the graphic element are stored as shown in FIGS. 8A and 8B, respectively.

FIG. 9 shows the relationship between the coordinate constraint condition and the element constraint condition in the coordinate input. FIG. 9A shows an example of coordinate constraint conditions, FIG. 9B shows an example of element constraint conditions, and FIG. 9C shows these two constraint conditions in a matrix when the coordinate input is performed based on these conditions. Show. In addition, in FIG.
The display contents of the cursor navigation information display area 30c under various conditions on the matrix of FIG. 9C are shown.

First, in the case of N in FIG. 9C in which neither the element constraint condition nor the coordinate constraint condition is present, the display is based on only the priority condition of the priority condition table 214 of the coordinate input method shown in FIG. The content is decided.

Next, in the case of A which has no coordinate constraint condition,
When the cursor C is on the graphic element designated by the element constraint condition, as shown in FIG.
Indicates the graphic element, and the coordinate display frame 32 displays according to the priority order condition of the priority order condition table 214. When the cursor C is not on the graphic element designated by the element constraint condition, as shown in FIG. 10B, the element display frame 31 means that there is no such graphic element, for example, "-" (hyphen). The coordinate display frame 32 displays a "finger" indicating the coordinate pointed by the cursor C.

Next, when the coordinate constraint condition is B, which is the designated coordinate point of the cursor, as shown in FIG. 10C, the element display frame 31 means that there is no such graphic element, for example, "-". The "(hyphen)" coordinate display frame 32 displays a "finger" indicating the coordinate pointed by the cursor C.

Next, when the element constraint condition and the coordinate constraint condition are C respectively, the element display frame 31 is under the cursor C as shown on the left side of (d) to (g) of FIG. Graphic elements (points, lines, circles, ellipses, etc.) are shown, and the coordinate display frame 32 has “intersection”, “edge”, “middle”,
Display "required" (point on element). When there is no graphic element under the cursor C, the element display frame 31 indicates invalid, as shown on the right side of (d) to (g) of FIG.
Is displayed and only the coordinate display frame 32 is displayed. In such an invalid state, an error occurs and the click operation is ignored.

Next, the element input will be described. The element input designates only the graphic element regardless of the coordinate points, and the user specifies the graphic element constraint conditions (point, line, line, etc.) previously specified in the user element constraint condition table 216 of FIG.
Circle, ellipse, curve, note, compound shape, etc.) can be specified. The element constraint condition table 213 shown in FIGS. 2 and 8B stores the element constraint conditions for each command (function) as described above.

Then, (1) the condition of the user element constraint condition table 216, and (2) the element constraint condition table 2
13 conditions and (3) the graphic element under the cursor C,
The graphic element to be displayed is determined in accordance with the three AND conditions of, for example, in the case of a circle, as shown in FIG.
“Circle” is displayed in the element display frame 31. Further, since the coordinate display frame 32 is not necessary for element input, it is always "/" (slash). If there is no corresponding graphic element under the above-mentioned AND condition, the element display frame 31 becomes "x" as shown in FIG. 11 (b).

Next, the operation of the cursor navigation apparatus of the present invention will be described with reference to the flowcharts shown in FIGS. This cursor navigation device operates as part of a conventional graphic processing device.

First, when a command (function) name is entered

Thus, the specified contents are confirmed in the device (step S13), and the confirmation data is output (step S14). If the user does not perform the click operation, the process returns from step S13 to step S5, and the operation from step 5 is repeated.

On the other hand, in the case of element input in step S3, the process proceeds to step S15 in FIG. 13 and the above-mentioned user element constraint condition table 216 in which desired constraint conditions are designated for each use of the user shown in FIG. A candidate list of graphic elements is created from the AND condition of the constraint conditions of the element constraint condition table 213 (steps S15 to S17).
If there is no graphic element satisfying the AND condition in the candidate list (step S18), navigation information of error
(See (b) of FIG. 11) is displayed (step S19).

On the other hand, if there is a graphic element satisfying the AND condition in the candidate list in step 18, all graphic elements under the cursor are input (picked up) (step S20) and collated with the above candidate list (step S21). ), Step S
From the constraint conditions of the element constraint condition table 216 for user of 15 and the constraint conditions of the element constraint condition table 213 of step S16 and the graphic element under the cursor, the cursor navigation of the display device 30 is performed for graphic elements satisfying these AND conditions. The information is displayed in the information display area 30c (see FIG. 1) (step S22). At this time, if there are a plurality of graphic elements under the cursor, they are displayed in the priority order based on the priority order condition table 215 of the element input method shown in FIG.

The user confirms the display content of the cursor navigation information display area 30c, confirms that the desired graphic element is designated, and operates the switch of the mouse 5.
When (click operation), the specified contents are confirmed in the device (step S23), and confirmation data is output (step S2).
4). If the user does not perform the click operation, the process returns from step S23 to step S20, and the operation from step 20 is repeated.
