The 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.
| qreal | det () const |
| QMatrix | invert ( bool * invertible = 0 ) const |
| QRect | map ( const QRect & rect ) const |
| QRegion | mapToRegion ( const QRect & rectangle ) const |
Returns the matrix's determinant.
See also determinant().
Returns an inverted copy of this matrix.
Use the inverted() function instead.
Creates 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.
Returns 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.
