JPH05290138A - Figure emphasizing and displaying method - Google Patents

Abstract

PURPOSE:To move a mouse on a list and confirm figure with a name and a shape, and to improve the operability by specifying the figure corresponding to an optional name and emphasizing and displaying it when the name is selected among displayed figure names. CONSTITUTION:When mouse cursor screen coordinate values as the coordinate values of the mouse cursor 40 on a screen are transmitted from a graphic display 10 to a processor 20, the values are converted into the real coordinate values of a coordinate system where shapes are defined according to the display position and display size on the screen. Then, it is decided whether or not a figure stored in a figure definition table 31 includes the specified actual coordinate values. Consequently, figures judged to include the real coordinate values (e.g. A, B, and D) are stored in a figure name table 32. The figure name list stored in this figure name table 32 is displayed on the screen so that the head figure name is at the position of the mouse cursor 40, and the figures corresponding to the name is emphasized and displayed. Therefore, the shape of the figure can easily be confirmed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for confirming the name of a graphic and its shape on a screen in a two-dimensional graphic processing system.

[0002]

2. Description of the Related Art As described in Japanese Patent Application Laid-Open No. 3-99369, a drawing management apparatus has been proposed which emphasizes a designated graphic on a facility drawing. This proposal specifies a method of highlighting the graphic in a specific hierarchy by selecting the hierarchy name displayed in the hierarchy display area of the screen, and specifying any graphic displayed in the graphic display area. By doing so, a method for highlighting a specific figure is provided.

[0003]

In the above-mentioned conventional example, when a graphic is highlighted, it is necessary to specify the graphic to be highlighted with a mouse cursor. However, when a plurality of figures are overlapped or the figures are adjacent to each other, it is difficult to point an arbitrary figure with a mouse cursor. Even in such a case, it is desirable that all the figures on the screen can be highlighted by some method.

It is an object of the present invention to solve the above problems and provide a method for highlighting an arbitrary figure displayed on the screen.

[0005]

In order to achieve the above object, according to the present invention, when an arbitrary position in a screen on which a graphic is displayed is designated, a display graphic including the designated position is specified. Then, the figure name corresponding to the specified figure is obtained. Next, the graphic name thus obtained is additionally displayed on the display graphic screen. When an arbitrary figure name is selected from the displayed figure names, the figure corresponding to the selected figure name is specified, and the specified figure is emphasized and displayed.

[0006]

Operation: When the user specifies the position on the screen where the graphic is displayed with the mouse, first the coordinate value of the specified position is changed from the coordinate value on the screen to the value of the coordinate system in which the graphic is defined. To be converted. Next, the figure definition data on the storage device is referred to, and all the figures including the specified position inside are searched from the defined figures. Then, the names of the retrieved figures are displayed on the screen in a list format. This figure name list continues to be displayed while the mouse button is pressed,
When the mouse button is released, the figure name list is deleted. When the user moves the mouse cursor on the figure name list while holding down the mouse button, it is detected which name in the figure name list the mouse cursor is pointing to, and the figure corresponding to the name pointed to by the mouse cursor is detected. Is highlighted. According to this method, any figure displayed on the screen can be highlighted, and the list of figure names need only be traced with the mouse cursor, so the shape of the figure can be easily confirmed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a block diagram of a graphic processing system showing an embodiment of the present invention. This system includes a graphic display 10 for displaying a graphic, a mouse 11 for designating a position on the graphic display and selecting a graphic name from the displayed graphic name list, and processing for performing various processes. Device 20, graphic definition table 3 for storing names of defined graphics and definition contents
1. A graphic name table 32 for storing the names of graphics including the position designated by the mouse 11.

FIG. 2 shows the contents of the graphic definition table 31.

In this embodiment, it is assumed that there are two types of figures: a single rectangular figure composed of a single rectangle and a non-single rectangular figure represented as the sum / difference of a plurality of rectangles (graphics). To do. The definition content of the graphic in the graphic definition table 31 differs depending on the type of graphic. The definition contents of the single rectangular graphic are the graphic name of the graphic, an identifier indicating that the graphic is a single rectangular graphic, a lower limit value and an upper limit value for the X coordinate of the graphic, and a lower limit value and an upper limit value for the Y coordinate. The definition content of a non-single rectangular figure includes a figure name of the figure, an identifier indicating that the figure is a non-single rectangular figure, n figure names (n ≧ 2) forming the figure, and between the figure. M operators (+ (sum) /-(difference):
m = n-1). For example, the arithmetic expression of the non-independent rectangular graphic G that is the sum (+) of the independent rectangular graphic E and the independent rectangular graphic F is “E + F”.

FIG. 3 is an example of a display screen of the graphic display 10. A, B, C and D in the figure represent defined figures. No graphics are highlighted at this point. Also, a mouse cursor 40 is displayed on the screen, and the position of the mouse cursor 40 is the mouse 11.
Moves in conjunction with the movement of.

The outline of the highlighting method of the present invention is as follows.

First, it is assumed that the user presses the mouse button at the position shown in FIG. 3 on the screen. At this time, the mouse cursor 4 is moved from the graphic display 10 to the processing device 20.
The mouse cursor screen coordinate value, which is 0 on the screen, is transmitted. The processing device 20 receives the mouse cursor screen coordinate value, and converts the mouse cursor screen coordinate value from the display position and display size of the screen to the actual coordinate value of the coordinate system in which the shape is defined by a known technique (publicly known). (Not shown in the flow chart since this is a technology of).

Next, it is determined whether or not the designated mouse cursor actual coordinate value is included in each figure stored in the figure definition table 31.

As a result of this determination, the figure (in the example of FIG. 3, A, B,
D) is stored in the figure name table 32. Finally, the graphic name list stored in the graphic name table 32 is displayed on the screen so that the graphic name at the top of the graphic name list is located at the position of the mouse cursor 40, and corresponds to the graphic name at the top of the graphic name list. Display the figure with emphasis.

FIG. 6 is an example of the display, and A, B and D in the figure name list are figure names. When the figure name list is displayed, the top figure name of the figure name list is displayed on the screen so that the mouse cursor 40 is positioned so that the mouse cursor 40 displays the top figure name “A” of the figure name list. The shape of the figure A is highlighted. While the graphic name list is being displayed, the processing device 20 monitors the position of the mouse cursor 40 at regular time intervals, and when the graphic name pointed to by the mouse cursor changes, the graphic with the mouse cursor 40 separated is highlighted. Is canceled to return to the normal display, and the graphic corresponding to the graphic name newly pointed by the mouse cursor is emphasized and displayed.

For example, when the user moves the mouse cursor 40 on the graphic name list from the graphic name "A" to the graphic name "B" as shown in FIG. 7 as shown in FIG.
The processing device 20 detects this, returns the figure A to the normal display state as shown in FIG. 7, and emphasizes the display of the figure B.
In this way, when the mouse cursor 40 is moved up and down on the list, the highlighted figures are switched one after another.

When the mouse button is released, the information is transmitted from the graphic display 10 to the processing device 20, and the processing device 20 detects this, deletes the graphic name list on the screen, and displays the highlighted graphic. To the normal display.

FIG. 4 and FIG. 5 are flowcharts of an embodiment showing a process of specifying a figure including a position designated by the mouse cursor 40 on the screen, among the figures being displayed on the screen.

The flowcharts of FIGS. 4 and 5 will be described below with reference to FIGS. 1, 2, and 3.

First, the internal figure flag is initialized to OFF (step 10), and then it is determined whether or not the figure Z to be judged is a single rectangular figure by referring to the figure definition table 31 (step 20). If the graphic Z is a single rectangular graphic, the subroutine A is executed by using the graphic Z as a subroutine check target graphic (step 30), and after returning from the subroutine, the process branches to step 110. If the result of determination in step 20 is that the figure Z is a non-independent rectangular figure, the figure in the first term in the arithmetic expression of figure Z is designated as the figure to be checked (step 40), and the figure Subroutine A is executed with the figure as a subroutine check figure (step 50). Next, it is confirmed whether all the graphics forming the graphics Z have been checked (step 60). If all the graphics have been checked, the process branches to step 110. If all the graphics forming the graphic Z have not been checked yet, the graphics of the item next to the item checked by the subroutine in the previous step as the graphics to be checked next are designated as the subroutine check target graphics (step 70). Next, it is confirmed whether the operator immediately before the figure to be checked is + (sum) or-(difference) (step 8).
0). If the operator is + (sum), subroutine A is executed (step 90), if the operator is-(difference), subroutine B is executed (step 100), and after returning from the subroutine, branch to step 60. To do. Step 1
In step 10, it is confirmed whether the figure internal flag is on (step 110). If it is on, it is determined that the figure Z is a figure including the position designated by the mouse cursor 40, and the figure name Z is the figure. Store in the name table 32 (step 120) and end. If it is off, it is determined that the graphic Z is a graphic that does not include the position designated by the mouse cursor 40, and the graphic name Z is not stored in the graphic name table 32 and the process ends.

Next, the subroutine A of FIG. 5 will be described.

The input information to the subroutine A is the X / Y actual coordinate values of the subroutine check target graphic and the mouse cursor 40.

First, X of the actual coordinate value of the mouse cursor 40
It is confirmed whether the coordinate value and the Y coordinate value are within the lower limit value and the upper limit value of the X coordinate and the Y coordinate of the subroutine check target graphic stored in the graphic definition table 31 (step 210). As a result of the confirmation, if the X coordinate value and the Y coordinate value of the actual coordinate value of the mouse cursor 40 are within the range between the lower limit value and the upper limit value, the figure internal flag is turned on to return (step 220). If not, it returns without doing anything.

Next, the subroutine B of FIG. 5 will be described.

The input information to the subroutine B is the same X / Y actual coordinate value of the subroutine check target graphic and the mouse cursor 40 as the input information in the subroutine A.

First, X of the actual coordinate value of the mouse cursor 40
It is confirmed whether or not the coordinate value / Y coordinate value is within the lower limit value and the upper limit value of the X coordinate / Y coordinate of the subroutine check target graphic stored in the graphic definition table 31 (step 250). As a result of the confirmation, if the X coordinate value and the Y coordinate value of the actual coordinate value of the mouse cursor 40 are within the range between the lower limit value and the upper limit value, the figure internal flag is turned off and the process returns (step 260). If not, it returns without doing anything.
