NAME

       wxBufferedPaintDC - Functions for wxBufferedPaintDC class

DESCRIPTION

       This  is  a  subclass of wxBufferedDC which can be used inside of an EVT_PAINT() event handler to achieve
       double-buffered   drawing.   Just   use   this   class   instead   of    wxPaintDC    and    make    sure
       wxWindow:setBackgroundStyle/2 is called with wxBG_STYLE_PAINT somewhere in the class initialization code,
       and  that's  all you have to do to (mostly) avoid flicker. The only thing to watch out for is that if you
       are using this class together with wxScrolled (not implemented in wx), you probably do not want  to  call
       wxScrolledWindow:prepareDC/2 on it as it already does this internally for the real underlying wxPaintDC.

       See: wxDC, wxBufferedDC, wxAutoBufferedPaintDC (not implemented in wx), wxPaintDC

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

DATA TYPES

       wxBufferedPaintDC() = wx:wx_object()

EXPORTS

       new(Window) -> wxBufferedPaintDC()

              Types:

                 Window = wxWindow:wxWindow()

       new(Window, Buffer) -> wxBufferedPaintDC()

       new(Window, Buffer :: [Option]) -> wxBufferedPaintDC()

              Types:

                 Window = wxWindow:wxWindow()
                 Option = {style, integer()}

       new(Window, Buffer, Options :: [Option]) -> wxBufferedPaintDC()

              Types:

                 Window = wxWindow:wxWindow()
                 Buffer = wxBitmap:wxBitmap()
                 Option = {style, integer()}

              As  with  wxBufferedDC,  you  may  either  provide the bitmap to be used for buffering or let this
              object create one internally (in the latter case, the size of the client part  of  the  window  is
              used).

              Pass  wxBUFFER_CLIENT_AREA  for  the  style parameter to indicate that just the client area of the
              window is buffered, or wxBUFFER_VIRTUAL_AREA to indicate that the buffer bitmap covers the virtual
              area.

       destroy(This :: wxBufferedPaintDC()) -> ok

              Copies everything drawn on the DC so far to the  window  associated  with  this  object,  using  a
              wxPaintDC.
