XmDataFieldCut — A DataField function that copies the
primary selection to the clipboard and deletes the selected

     #include <Xm/DataF.h>
Boolean XmDataFieldCut(
Widget widget,
Time time);

     XmDataFieldCut copies the primary selected text to the
clipboard and then deletes the primary selected text.  This
routine calls the widget’s XmNvalueChangedCallback and
verification callbacks, either XmNmodifyVerifyCallback or
XmNmodifyVerifyCallbackWcs, or both. If both verification
callback lists are registered, the procedures of the
XmNmodifyVerifyCallback list are executed first and the
resulting data is passed to the XmNmodifyVerifyCallbackWcs

     This routine calls the XmNconvertCallback procedures,
possibly multiple times, with the selection member of the
XmConvertCallbackStruct set to CLIPBOARD and with the parm
member set to XmMOVE.  If the transfer is successful, this
routine then calls the XmNconvertCallback procedures for the
CLIPBOARD selection and the DELETE target.

widget    Specifies the DataField widget ID.

time      Specifies the time at which the selection value is
          to be modified. This should be the time of the
          event that triggered this request.

     For a complete definition of DataField and its
associated resources, see XmDataField(3).

     This function returns False if the primary selection is
NULL, if the widget does not own the primary selection, if
the function is unable to gain ownership of the clipboard
selection, or if no data is placed on the clipboard.
Otherwise, it returns True.
