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)

Arguments

`src1`	a `GdkRectangle`
`src2`	a `GdkRectangle`

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 ]
