|phoenix_title| **wx.PaintDC**
==========================================================================================================================================
A :ref:`wx.PaintDC` 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 :ref:`wx.PaintDC` object. If you have an EVT_PAINT() handler, you `must` create a :ref:`wx.PaintDC` object within it even if you don't actually use it.
Using :ref:`wx.PaintDC` 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.
To draw on a window from outside your EVT_PAINT() handler, construct a :ref:`wx.ClientDC` object.
To draw on the whole window including decorations, construct a :ref:`wx.WindowDC` object (Windows only).
A :ref:`wx.PaintDC` object is initialized to use the same font and colours as the window it is associated with.
