以下成员源于类 QMatrix are part of the Qt compatibility layer. We advise against using them in new code.
| QMatrix | invert (bool * invertible = 0) const |
| QRect | map (const QRect & rect ) const |
| QRegion | mapToRegion (const QRect & rectangle ) const |
Returns an inverted copy of this matrix.
使用 inverted () 函数代替。
创建并返回 QRect object that is a copy of the given rectangle, mapped into the coordinate system defined by this matrix.
使用 mapRect () 函数代替。
Returns the transformed rectangle rectangle 作为 QRegion object. A rectangle which has been rotated or sheared may result in a non-rectangular region being returned.
使用 mapToPolygon () 或 map () 函数代替。
