| 3 | A wxPaintDC must be constructed if an application wishes to paint on the |
| 4 | client area of a window from within an {\bf OnPaint} event. |
| 5 | This should normally be constructed as a temporary stack object; don't store |
| 6 | a wxPaintDC object. If you have an OnPaint handler, you {\it must} create a wxPaintDC |
| 7 | object within it even if you don't actually use it. |
| 8 | |
| 9 | Using wxPaintDC within OnPaint is important because it automatically |
| 10 | sets the clipping area to the damaged area of the window. Attempts to draw |
| 11 | outside this area do not appear. |
| 12 | |
| 13 | To draw on a window from outside {\bf OnPaint}, construct a \helpref{wxClientDC}{wxclientdc} object. |
| 14 | |
| 15 | To draw on the whole window including decorations, construct a \helpref{wxWindowDC}{wxwindowdc} object |
| 16 | (Windows only). |
