Qt 3 Support Members for QMatrixThe following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code. Public Functions
Member Function DocumentationQMatrix QMatrix::invert ( bool * invertible = 0 ) constReturns an inverted copy of this matrix. Use the inverted() function instead. QRect QMatrix::map ( const QRect & rect ) constCreates and returns a QRect object that is a copy of the given rectangle, mapped into the coordinate system defined by this matrix. Use the mapRect() function instead. QRegion QMatrix::mapToRegion ( const QRect & rectangle ) constReturns the transformed rectangle rectangle as a QRegion object. A rectangle which has been rotated or sheared may result in a non-rectangular region being returned. Use the mapToPolygon() or map() function instead.
