<p><P>PROBLEM TO BE SOLVED: To efficiently and intuitively erase a straight line connecting icons. <P>SOLUTION: At the time of erasing a straight line 600 in a figure, the left button of a mouse 112 is pushed down on the straight line, and dragged to a direction(either upward or downward) vertical to the straight line in that state, and when it is dragged in a certain distance or more, the straight line 600 is switched from a solid line to a dotted line, and when the drag operation is ended and switched to another operation, the dotted line is also erased. When the dotted line is clicked while the dotted line is displayed, the dotted line can be restored to the solid line (the erasure of the straight line is canceled). <P>COPYRIGHT: (C)2003,JPO</p> |
