  13 wxDCClipper is a small helper class for setting a clipping region on a
  14 \helpref{wxDC}{wxdc} and unsetting it automatically. An object of wxDCClipper
  15 class is typically created on the stack so that it is automatically destroyed
  16 when the object goes out of scope. A typical usage example:
  17
  18 \begin{verbatim}
  19     void MyFunction(wxDC& dc)
  20     {
  21         wxDCClipper clip(rect);
  22         ... drawing functions here are affected by clipping rect ...
  23     }
  24
  25     void OtherFunction()
  26     {
  27         wxDC dc;
  28         MyFunction(dc);
  29         ... drawing functions here are not affected by clipping rect ...
  30     }
  31 \end{verbatim}

  61 Sets the clipping region to the specified region \arg{r} or rectangle specified
  62 by either a single \arg{rect} parameter or its position (\arg{x} and \arg{y})
  63 and size (\arg{w} ad \arg{h}).
  64
  65 The clipping region is automatically unset when this object is destroyed.
