bool	intersects (const QPointF &center, int width, int height, double rotationDegrees=0.0) const

Detailed Description

Checks if two potentially rotated rectangles intersect.

This class checks if two rectangles overlap. It is more general that QRect::intersects in that the rectangles are not necessarily aligned to the axes (that is they can be specified as rotated around their center points).
