Ejemplos

• El ejemplo siguiente está diseñado para su uso con Windows Forms y requiere PaintEventArgse, que es un parámetro del Paint controlador de eventos. En el ejemplo de código se muestra cómo usar desde Data un RegionData objeto para establecer para Data otro RegionData.

private:
   void DemonstrateRegionData2( PaintEventArgs^ e )
