<p>PURPOSE:To plot a functional symbol in which a fixed symbol is made into function on the fixed symbol by deciding an area overwritten by a widget when display processing is applied to an X window set on the screen of a CRT display. CONSTITUTION:The overwriting area recording processing part 31 of a display processing part 3 in a computer device 1 sets a rectangular widget overwritten on the window as a functional symbol plotting area, and also, records the coordiate data and vertical/horizontal length of the widget on a table. A plotting screen decision processing part 32 retrieves the table when the fixed symbol is plotted on the window, and decides whether or not the area desired to plot is the overwritten area, and designates the widget as the plotting screen when it is the overwritten area, and the window as the plotting screen when it is not.</p> |
