<description><p><seeerl marker="wxBitmapDataObject"><c>wxBitmapDataObject</c></seeerl> is a specialization of <seeerl marker="wxDataObject"><c>wxDataObject</c></seeerl> for bitmap data. It can be used without change to paste data into the <seeerl marker="wxClipboard"><c>wxClipboard</c></seeerl> or a <c>wxDropSource</c> (not implemented in wx). 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.
      </p><p>This class may be used as is, but <seemfa marker="#getBitmap/1"><c>getBitmap/1</c></seemfa> may be overridden to increase efficiency.
      </p><p>See: <url href="https://docs.wxwidgets.org/3.1/overview_dnd.html#overview_dnd">Overview dnd</url>, <seeerl marker="wxDataObject"><c>wxDataObject</c></seeerl>, <c>wxDataObjectSimple</c> (not implemented in wx), <seeerl marker="wxFileDataObject"><c>wxFileDataObject</c></seeerl>, <seeerl marker="wxTextDataObject"><c>wxTextDataObject</c></seeerl>, <seeerl marker="wxDataObject"><c>wxDataObject</c></seeerl>
      </p>
  <p>This class is derived (and can use functions) from:
