<p>PURPOSE:To facilitate the identification of >=2 cursors and to allow the restoration of normal background images by making display control in such a manner as to avoid the generation of overlapping by an overlap deciding means and a moving position control means when there are >=2 cursors within the same screen. CONSTITUTION:A cursor moving position control means 12 transmits the cursor movement instruction including moving destination positions to all cursor servers upon decision that the events received by a cursor overlap deciding means 11 do not generate the overlap with the other cursors in the region of the moving destination in the cursor movement. This means compares the width and height of the overlapped part when the overlap arises. The means determines the position where the cursors are not overlapped by controlling the position of the moving destination along the axis of the smaller width or height so as to attain 0. The means makes instruction as to which cursor is to be displayed to which of all the cursor servers.</p> |
