<H2>wxPaintDC</H2>
<P>
A wxPaintDC must be constructed if an application wishes to paint on the
client area of a window from within an <B>OnPaint</B> event.
This should normally be constructed as a temporary stack object; don't store
a wxPaintDC object. If you have an OnPaint handler, you <I>must</I> create a wxPaintDC
object within it even if you don't actually use it.<P>
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.<P>
To draw on a window from outside <B>OnPaint</B>, construct a <A HREF="wx43.htm#wxclientdc">wxClientDC</A> object.<P>
To draw on the whole window including decorations, construct a <A HREF="wx261.htm#wxwindowdc">wxWindowDC</A> object
(Windows only).<P>
