+wxBitmapDataObject is a specialization of wxDataObject for bitmap data. It can
+be used without change to paste data into the
+\helpref{wxClipboard}{wxclipboard} or a \helpref{wxDropSource}{wxdropsource}. A
+user may wish to derive a new class from this class for providing a bitmap
+on-demand in order to minimize memory consumption when offering data in several
+formats, such as a bitmap and GIF.
+
+\pythonnote{If you wish to create a derived wxBitmapDataObject class in
+wxPython you should derive the class from wxPyBitmapDataObject
+in order to get Python-aware capabilities for the various virtual
+methods.}

+This class may be used as is, but
+\helpref{GetBitmap}{wxbitmapdataobjectgetbitmap} may be overridden to increase
+efficiency.
