# wxWindowDC(3erl)

Functions for wxWindowDC class

## NAME

wxWindowDC - Functions for wxWindowDC class

## DESCRIPTION

A *wxWindowDC* must be constructed if an application wishes to paint on the whole area of a window (client and decorations). This should normally be constructed as a temporary stack object; don't store a *wxWindowDC* object.

To draw on a window from inside an EVT\_PAINT() handler, construct a *wxPaintDC* object instead.

To draw on the client area of a window from outside an EVT\_PAINT() handler, construct a *wxClientDC* object.

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

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

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