The following class members are part of the Qt 3 compatibility layer. They are provided to help you port old code to Qt 4. We strongly advise against using them in new code.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use mapRect() instead.
Returns the transformed rectangle rect.
A rectangle which has been rotated or sheared may result in a non-rectangular region being returned.
Calling this method can be expensive, if rotations or shearing are used. If you just need to know the bounding rectangle of the returned region, use mapRect() which is a lot faster than this function.
See also QMatrix::mapRect().
