DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments and operations of the present invention will be sequentially described in detail with reference to FIGS.

FIG. 2 is a flowchart illustrating the operation of the present invention (automatic generation of an attribute table). In FIG. 2, S
1 initializes an attribute table. This initializes (clears), for example, an attribute table 31 shown in FIG.

In step S2, an object in the editing area is extracted. In S3, it is determined whether the attribute is a new attribute. S2 and S3 are
For example, it is determined whether the attribute of one object extracted from the object (an example in the editing area) displayed on the screen of FIG. 4A (described later) is new (is the first attribute registered in the attribute table). If YES, the object is added to the attribute table in S4, that is, as shown in the attribute table 31 of FIG. A rectangular symbol representing “square” is added to the attribute table 31, and the process proceeds to S5. On the other hand, if NO in S3, S5
Proceed to.

In step S5, it is determined whether all objects have been extracted. If YES, a series of attribute tables 3
The addition to 1 is completed. On the other hand, if NO, the process returns to S2 and repeats.

As described above, for example, all the attributes of the object displayed on the screen shown in FIG. 4A to be described later are extracted, and a symbol representing the attribute is extracted from the attribute table 31 shown in FIG.
Can be set as shown in FIG.

FIG. 3 shows a flowchart (object selection) for explaining the operation of the present invention. This is a procedure when the target object is selected using the attribute table after the attribute table is created in FIG. 2 described above.

In FIG. 3, S11 determines a target attribute. This corresponds to the selection information being obtained from the attribute table 31, for example, when the user clicks and selects “△” with the mouse from the attribute table 31 displayed on the screen of FIG. Then, the selected attribute is determined (for example, △ (the attribute “triangle” of the object) is determined).

In step S12, it is determined whether the mode is the mouse position limited selection mode. This is to determine whether or not a mode for selecting one object limited by the mouse position is specified. Y
In the case of ES, in steps S13 to S17, one of the objects having the determined attribute which can be selected with the mouse is selected.
A process for selecting one or the like is performed. On the other hand, in the case of NO,
The processing from S18 to S21 is performed.

In step S13, a position is designated by the auxiliary input device. This is because, since the attribute is determined in S11, only the object having the determined attribute is highlighted in the selectable state on the screen, and the mouse is operated from the object in the selectable state to operate the object. Move the mouse cursor inside and click to select.

In step S14, an object including a position as an area is extracted. That is, in response to the mouse cursor being positioned and clicked in S13, an object including the position of the clicked mouse cursor as an area is extracted.

A step S15 decides whether or not the object exists. In the case of YES, the process proceeds to S16. In the case of NO, it is determined that no object exists in the area of the selected point, and the process ends.

In step S16, the point selected by the mouse cursor in step S15 is determined to be the same as the type of the object to be selected. That is, it is determined whether or not the determined attribute is the same as the attribute of the object including the point selected by the mouse cursor as an area. If YES, the selection state is determined in S17, and the process ends. On the other hand, if NO, the process returns to S14 and repeats.

Through the above steps S13 to S17, it is possible to easily, accurately and quickly select one object designated by the mouse cursor from the selectable objects having the determined attributes.

In step S18, an object in the editing area is extracted. A step S19 decides whether or not the attribute matches the attribute of the object. In the case of YES, the object can be selected (highlighted to display the selectable state), and the process proceeds to S21. On the other hand, in the case of NO, the process proceeds to S21.

A step S21 decides whether or not all the objects have been extracted. If YES, the process ends. If NO, the process returns to S18 and repeats. From S18 to S2
By setting 1, all the objects having the attribute determined in S11 are made selectable and can be highlighted on the screen, and one of them can be easily, accurately, and quickly selected with the mouse cursor. Becomes

FIG. 4 is a diagram (part 1) for explaining the operation of the present invention. FIG. 4A shows a state in which objects having a plurality of attributes to be edited are displayed on the screen and the attribute table 31 is displayed on the automatically generated screen. Here, it is displayed as described below on the right side.

Editing area: This is an area to be edited, and the whole or a part thereof is displayed on the screen. Mouse cursor: A mouse cursor that can be moved / selected with a mouse is displayed on the screen.

Circle object: An object whose attribute is a circle is displayed on the screen as shown in the figure. Triangular object: An object with a triangular attribute is displayed on the screen as shown.

Square object: An object having a square attribute is displayed on the screen as shown in the figure. Line object: An object having a line attribute is displayed on the screen as shown.

Rectangular object: An object whose attribute is a character is displayed on the screen as shown in the figure. Arrow object: An object having an arrow attribute is displayed on the screen as shown.

Selection palette: Attribute table 3 on the screen
1, a selection palette (パ レ ッ ト, △, □, |, A (representing a character), ↑) is displayed, and the attributes of the object are represented by symbols.

When the mouse cursor is positioned within the area of the selection pallet "△" on the attribute table 31 and clicked in the above displayed state, the pallet "▲" is added to the mouse cursor as shown in the figure. Move with the mouse cursor (the user can always recognize which attribute is selected).

FIG. 4B shows an attribute table 3 on the screen.
1 shows a state in which the selection pallet “△” is selected from within 1. In this state, as shown in the figure, a state is shown in which the selected palette “▲” (indicating that palette “△” is selected) is added to the mouse cursor and can be moved together.

In the above displayed state, when the mouse cursor is moved and the left mouse button is clicked and selected on the area including the triangular object, the state becomes as shown in FIG. 4C.

FIG. 4C shows a state where the mouse cursor (with a selection palette 付 加 added) is positioned on an object having the same attribute and clicked to select it. At this time, the triangle object with the attribute of ▲ is highlighted, so if you position the mouse cursor in this area and click to select, even if there are objects with other attributes as shown in the figure, the selected A triangle is displayed at the vertex of the triangular object to highlight it so as to make it easier to recognize that it has been selected.

As shown in FIGS. 4A, 4B, and 4C, when an attribute to be selected is selected from the attribute table 31 with a mouse cursor, a selection palette of the selected attribute is displayed on the mouse cursor. It is possible to add, move together, position the mouse cursor within the highlighted object and select it, and easily, accurately, and quickly select the target object.

FIG. 5 is a diagram (part 2) for explaining the operation of the present invention. FIG. 5A shows a state where the selection pallet “□” is selected from the attribute table 31 on the screen in the state of FIG. 4A. In this state, as shown in the figure, the selected pallet “■” is added to the mouse cursor and moves together.

FIG. 5B shows a state where the mouse cursor is positioned and selected at the same position as that of FIG. 4C described above. In this case, as shown in the figure, 頂点 is displayed at each vertex of the square object selected in FIG. 5A to facilitate recognition of the selection.

As described above, the attribute (here, “□”) is selected from the attribute table 31 displayed on the screen, and the mouse cursor is added with ■, and is moved together. ) When clicked at the same position, (c) of FIG.
Here, different from the case of (triangle object), it is now possible to easily, accurately and quickly select a square object.

FIG. 6 shows an example of an object table according to the present invention. In this case, the objects provided in the editing target area displayed on the screen and the attributes thereof, and the image of the selection pallet (symbol) displayed on the attribute table 31 are registered. Here, the attribute is an attribute (an attribute such as a circle, a triangle, a square, a straight line, or a character) of the object in the region to be edited displayed on the screen.

Data is data representing an object (for example, in the case of a circle, center coordinates, radius, etc.). The image data is an image for displaying the above-mentioned selection palette (symbol) (for example, in the case of a circle object, a dot image of “〇”).

Others: As described above, the attributes, data, image data (image data of the selected pallet), etc. of all the objects in the editing object to be displayed on the screen are registered in the object table 3 as described above. As described above, it is possible to automatically display the image data (the image of the selected pallet (symbol)) in the attribute table 31 when displaying the object in the editing target area on the screen.

[0044]

As described above, according to the present invention,
Since a configuration is adopted in which only the object having the designated attribute is selectable on the screen and the target object is selected, the target object can be selected easily, accurately, and quickly. As a result, since the selection operation on the object type other than the selection target is restricted, it is possible to greatly reduce human mistakes such as erroneous selection of the object at the time of editing, and efficiently perform the object editing work. It becomes possible.
