graphic orders defining those portions of said graphic objects
not overlapped, and driving a graphic display device with said
modified graphic orders to display said portion of said
graphic objects not overlapped.
Independent claim 1 is reproduced as follows:
1. A method of displaying, on a display terminal,
overlapping windows containing graphics objects defined by
graphics orders comprising the steps of:
obtaining a first list of graphic orders for graphic
objects in a first window of the overlapping windows and a
second list of graphic orders for graphic objects in a second
window of the overlapping windows, wherein the second window
has a higher priority than the first window;
processing the first list to identify nonoverlapping
graphic objects, wherein the nonoverlapping graphic objects
are not within an overlapping portion of the first and second
windows;
processing the second list of graphic orders and the
nonoverlapping graphic objects to generate a list of modified
graphic orders; and
driving the display terminal, with the list of
modified graphics orders to display the graphic objects of the
second window and the nonoverlapping graphic objects of the
first window.
