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.

This class is derived (and can use functions) from: wxWindowDC wxDC
wxWidgets docs: wxPaintDC
wxPaintDC() = wx:wx_object()
new(Window) -> wxPaintDC()
Window = wxWindow:wxWindow()
Pass a pointer to the window on which you wish to paint.
destroy(This :: wxPaintDC()) -> ok
Destroys the object.
