<description><p>A <seeerl marker="wxPaintDC"><c>wxPaintDC</c></seeerl> 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 <seeerl marker="wxPaintDC"><c>wxPaintDC</c></seeerl> object. If you have an EVT_PAINT() handler, you <c>must</c> create a <seeerl marker="wxPaintDC"><c>wxPaintDC</c></seeerl> object within it even if you don't actually use it.
</p><p>Using <seeerl marker="wxPaintDC"><c>wxPaintDC</c></seeerl> 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.
</p><p>A <seeerl marker="wxPaintDC"><c>wxPaintDC</c></seeerl> object is initialized to use the same font and colours as the window it is associated with.
</p><p>See: <seeerl marker="wxDC"><c>wxDC</c></seeerl>, <seeerl marker="wxClientDC"><c>wxClientDC</c></seeerl>, <seeerl marker="wxMemoryDC"><c>wxMemoryDC</c></seeerl>, <seeerl marker="wxWindowDC"><c>wxWindowDC</c></seeerl>, <seeerl marker="wxScreenDC"><c>wxScreenDC</c></seeerl>
