wxDCClipper is a small helper class for setting a clipping region on a wxDC and unsetting it automatically. An object of wxDCClipper class is typically created on the stack so that it is automatically destroyed when the object goes out of scope. A typical usage example:

    void MyFunction(wxDC& dc)
        wxDCClipper clip(rect);
        ... drawing functions here are affected by clipping rect ...

    void OtherFunction()
        wxDC dc;
        ... drawing functions here are not affected by clipping rect ...
