wxPaintDC - Functions for wxPaintDC class


A wxPaintDC must be constructed if an application wishes to paint on the client area of a window from within an EVT_PAINT() event handler. This should normally be constructed as a temporary stack object; don't store a wxPaintDC object. If you have an EVT_PAINT() handler, you 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.

A wxPaintDC object is initialized to use the same font and colours as the window it is associated with.

See: wxDC, wxClientDC, wxMemoryDC, wxWindowDC, wxScreenDC

This class is derived (and can use functions) from: wxWindowDC wxDC
