This should normally be constructed as a temporary stack object; don't store a wxPaintDC object. If you have an EVT_PAINT() handler, you @e must create a wxPaintDC object within it even if you don't actually use it. Using wxPaintDC within your EVT_PAINT() handler is important because it automatically sets the clipping area to the damaged area of the window. Attempts to draw outside this area do not appear. To draw on a window from outside your EVT_PAINT() handler, construct a wxClientDC object. To draw on the whole window including decorations, construct a wxWindowDC object (Windows only). A wxPaintDC object is initialized to use the same font and colours as the window it is associated with. @library{wxcore} @category{dc} @see wxDC, wxClientDC, wxMemoryDC, wxWindowDC, wxScreenDC */ class wxPaintDC : public wxWindowDC { public: /** Constructor.
