Summary

Tests if two rectangles intersect.

Pascal

 function RectIntersectRect(const R1: TRect; const R2: TRect): Boolean;

Parameters

Parameters	Description
const R1: TRect	The first rectangle.
const R2: TRect	The second rectangle.

Return Value

If the two rectangles intersect the function returns True, otherwise it returns False.

Description

RectIntersectRect tests whether the two rectangles intersect. Note that the function performs the test by actually calculating the intersection. Therefore, don't write code like this: if RectIntersectRect then R := RectIntersection(...). Instead use RectIntersection directly and compare the result against the null rectangle.
