1548 "This simple class provides a simple way to avoid flicker: when drawing
1549 on it, everything is in fact first drawn on an in-memory buffer (a
1550 `wx.Bitmap`) and then copied to the screen only once, when this object
1551 is destroyed. You can either provide a buffer bitmap yourself, and
1552 reuse it the next time something needs painted, or you can let the
1553 buffered DC create and provide a buffer bitmap itself.
1555 Buffered DCs can be used in the same way as any other device context.
1556 wx.BufferedDC itself typically replaces `wx.ClientDC`, if you want to
1557 use it in your EVT_PAINT handler, you should look at
1558 `wx.BufferedPaintDC`. You can also use a wx.BufferedDC without
1559 providing a target DC. In this case the operations done on the dc
1560 will only be written to the buffer bitmap and *not* to any window, so
1561 you will want to have provided the buffer bitmap and then reuse it
1562 when it needs painted to the window.
1564 Please note that GTK+ 2.0 and OS X provide double buffering themselves
1565 natively. You may want to use `wx.Window.IsDoubleBuffered` to
1566 determine whether you need to use buffering or not, or use
1567 `wx.AutoBufferedPaintDC` to avoid needless double buffering on systems
1568 that already do it automatically.
1573 class wxBufferedDC : public wxMemoryDC

1581 :param dc: The underlying DC: everything drawn to this object will
1582 be flushed to this DC when this object is destroyed. You may
1583 pass ``None`` in order to just initialize the buffer, and not
1586 :param buffer: If a `wx.Size` object is passed as the 2nd arg then
1587 it is the size of the bitmap that will be created internally
1588 and used for an implicit buffer. If the 2nd arg is a
1589 `wx.Bitmap` then it is the explicit buffer that will be
1590 used. Using an explicit buffer is the most efficient solution
1591 as the bitmap doesn't have to be recreated each time but it
1592 also requires more memory as the bitmap is never freed. The
1593 bitmap should have appropriate size, anything drawn outside of
1594 its bounds is clipped. If wx.NullBitmap is used then a new
1595 buffer will be allocated that is the same size as the dc.
1597 :param style: The style parameter indicates whether the supplied buffer is
1598 intended to cover the entire virtual size of a `wx.ScrolledWindow` or
1599 if it only covers the client area. Acceptable values are
1600 ``wx.BUFFER_VIRTUAL_AREA`` and ``wx.BUFFER_CLIENT_AREA``.
