gdkRectangleIntersect: gdkRectangleIntersect
Description
Calculates the intersection of two rectangles. It is allowed for
dest to be the same as either src1 or src2. If the rectangles
do not intersect, dest's width and height is set to 0 and its x
and y values are undefined. If you are only interested in whether
the rectangles intersect, but not in the intersecting area itself,
pass NULL for dest.Usage
gdkRectangleIntersect(src1, src2)
Value
A list containing the following elements:
- retval
- [logical]
TRUE if the rectangles intersect. dest- return location for the intersection of
src1 and src2, or NULL. [ allow-none ]
