NAME
       wxBitmapDataObject - Functions for wxBitmapDataObject class

DESCRIPTION
       wxBitmapDataObject is a specialization of wxDataObject for bitmap data.
       It can be used without change to paste data into the wxClipboard  or  a
       wxDropSource  (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 min-
       imize memory consumption when offering data in several formats, such as
       a bitmap and GIF.

       This class may be used as is, but  getBitmap/1  may  be  overridden  to
       increase efficiency.

       See: Overview dnd, wxDataObject, wxDataObjectSimple (not implemented in
       wx), wxFileDataObject, wxTextDataObject, wxDataObject

       This class is derived (and can use functions) from: wxDataObject

       wxWidgets docs: wxBitmapDataObject

DATA TYPES
       wxBitmapDataObject() = wx:wx_object()

EXPORTS
       new() -> wxBitmapDataObject()

       new(Options :: [Option]) -> wxBitmapDataObject()

       new(Bitmap) -> wxBitmapDataObject()

              Types:

                 Bitmap = wxBitmap:wxBitmap()

              Constructor, optionally passing a  bitmap  (otherwise  use  set-
              Bitmap/2 later).

       getBitmap(This) -> wxBitmap:wxBitmap()

              Types:

                 This = wxBitmapDataObject()

              Returns the bitmap associated with the data object.

              You  may  wish  to  override  this method when offering data on-
              demand, but this is not required by  wxWidgets'  internals.  Use
              this method to get data in bitmap form from the wxClipboard.

       setBitmap(This, Bitmap) -> ok

              Types:

                 This = wxBitmapDataObject()
                 Bitmap = wxBitmap:wxBitmap()

              Sets the bitmap associated with the data object.

              This  method  is called when the data object receives data. Usu-
              ally there will be no reason to override this function.

       destroy(This :: wxBitmapDataObject()) -> ok

              Destroys the object.
