}}\label{wxbitmapdataobject
}
3 wxBitmapDataObject is a specialization of wxDataObject for bitmap data. It can
4 be used without change to paste data into the
5 \helpref{wxClipboard
}{wxclipboard
} or a
\helpref{wxDropSource
}{wxdropsource
}. A
6 user may wish to derive a new class from this class for providing a bitmap
7 on-demand in order to minimize memory consumption when offering data in several
8 formats, such as a bitmap and GIF.

}{\void}
43 Returns the bitmap associated with the data object. You may wish to override
44 this method when offering data on-demand, but this is not required by
45 wxWindows' internals. Use this method to get data in bitmap form from
46 the
\helpref{wxClipboard
}{wxclipboard
}.

}\label{wxbitmapdataobjectsetbitmap

50 \func{virtual void
}{SetBitmap
}{\param{const wxBitmap\&
}{bitmap
}}
52 Sets the bitmap associated with the data object. This method is called when the
53 data object receives data. Usually there will be no reason to override this
