- @class wxPaintDC
- 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 @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
