# Device Context to paint on a window outside an on_paint handler. It is
# recommended that PaintDC is used in preference to this class.

  # This class should not be instantiated directly in wxRuby; it should

  # DC. This ensures that the DC is cleaned up at the correct time,
  # avoiding errors and segfaults on exit.
