# View Source wxPaintDC (wx v2.4.3)

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.

- `wxClientDC`

This class is derived, and can use functions, from:

- `wxWindowDC`

- `wxDC`
