Get an event's rectangle set
PhRect_t *PhGetRects( PhEvent_t const *event );
ph
This function gets the rectangle set associated with the specified
event. The number of rectangles in the event's rectangle set is given
by event->num_rects.
In the case of an expose event, this function returns a pointer to the
list of rectangles that need to be repaired. In the case of a pointer
event, only one rectangle is associated with the event — the one
associated with the current position of the pointer.
For more information on the meaning of the rectangle set for
different event types,
see the event types described for the
PhEvent_t
structure.
A pointer to the rectangles associated
with the event.
