# wxPaintDC(3erl)

Functions for wxPaintDC class

## NAME

wxPaintDC - Functions for wxPaintDC class

## DESCRIPTION

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 *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.

A *wxPaintDC* object is initialized to use the same font and colours as the window it is associated with.

See: *wxDC*, *wxClientDC*, *wxMemoryDC*, *wxWindowDC*, *wxScreenDC*

This class is derived (and can use functions) from: *wxWindowDC* *wxDC*
