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.
