3wxBitmapDataObject is a specialization of wxDataObject for bitmap data. It can
4be used without change to paste data into the
5\helpref{wxClipboard}{wxclipboard} or a \helpref{wxDropSource}{wxdropsource}. A
6user may wish to derive a new class from this class for providing a bitmap
7on-demand in order to minimize memory consumption when offering data in several
8formats, such as a bitmap and GIF.
9
10\pythonnote{If you wish to create a derived wxBitmapDataObject class in
11wxPython you should derive the class from wxPyBitmapDataObject
12in order to get Python-aware capabilities for the various virtual
13methods.}

16
17This class may be used as is, but
18\helpref{GetBitmap}{wxbitmapdataobjectgetbitmap} may be overridden to increase
19efficiency.

41Constructor, optionally passing a bitmap (otherwise use
42\helpref{SetBitmap}{wxbitmapdataobjectsetbitmap} later).

46\constfunc{virtual wxBitmap}{GetBitmap}{\void}
47
48Returns the bitmap associated with the data object. You may wish to override
49this method when offering data on-demand, but this is not required by
50wxWidgets' internals. Use this method to get data in bitmap form from
51the \helpref{wxClipboard}{wxclipboard}.
52
53\membersection{wxBitmapDataObject::SetBitmap}\label{wxbitmapdataobjectsetbitmap}
54
55\func{virtual void}{SetBitmap}{\param{const wxBitmap\& }{bitmap}}
56
57Sets the bitmap associated with the data object. This method is called when the
58data object receives data. Usually there will be no reason to override this
59function.
