\section{\class{wxPaintDC}}\label{wxpaintdc}
|
|
|
|
A wxPaintDC must be constructed if an application wishes to paint on the
|
|
client area of a window from within an {\bf OnPaint} event.
|
|
This should normally be constructed as a temporary stack object; don't store
|
|
a wxPaintDC object.
|
|
|
|
Using wxPaintDC within OnPaint 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 {\bf OnPaint}, construct a \helpref{wxClientDC}{wxclientdc} object.
|
|
|
|
To draw on the whole window including decorations, construct a \helpref{wxWindowDC}{wxwindowdc} object
|
|
(Windows only).
