NAME
      XtOwnSelection, XtDisownSelection - set selection owner

SYNTAX
      Boolean XtOwnSelection(w, selection, time, convert_proc, lose_selection,
      done_proc)
            Widget w;
            Atom selection;
            Time time;
            XtConvertSelectionProc convert_proc;
            XtLoseSelectionProc lose_selection;
            XtSelectionDoneProc done_proc;

      void XtDisownSelection(w, selection, time)
            Widget w;
            Atom selection;
            Time time;

ARGUMENTS
      convert_proc
                Specifies the procedure that is to be called whenever someone
                requests the current value of the selection.

      done_proc Specifies the procedure that is called after the requestor has
                received the selection or NULL if the owner is not interested
                in being called back.

      lose_selection
                Specifies the procedure that is to be called whenever the
                widget has lost selection ownership or NULL if the owner is not
                interested in being called back.

      selection Specifies an atom that describes the type of the selection (for
                example, XA_PRIMARY, XA_SECONDARY, or XA_CLIPBOARD).

      time      Specifies the timestamp that indicates when the selection
                ownership should commence or is to be relinquished.

      w         Specifies the widget that wishes to become the owner or to
                relinquish ownership.

DESCRIPTION
      The XtOwnSelection function informs the Intrinsics selection mechanism
      that a widget believes it owns a selection.  It returns True if the
      widget has successfully become the owner and False otherwise.  The widget
      may fail to become the owner if some other widget has asserted ownership
      at a time later than this widget.  Note that widgets can lose selection
      ownership either because someone else asserted later ownership of the
      selection or because the widget voluntarily gave up ownership of the
      selection.  Also note that the lose_selection procedure is not called if
      the widget fails to obtain selection ownership in the first place.

XtOwnSelection(3Xt)         X Version 11(Release 3)         XtOwnSelection(3Xt)


      The XtDisownSelection function informs the Intrinsics selection mechanism
      that the specified widget is to lose ownership of the selection.  If the
      widget does not currently own the selection either because it lost the
      selection or because it never had the selection to begin with,
      XtDisownSelection does nothing.

      After a widget has called XtDisownSelection, its convert procedure is not
      called even if a request arrives later with a timestamp during the period
      that this widget owned the selection.  However, its done procedure will
      be called if a conversion that started before the call to
      XtDisownSelection finishes after the call to XtDisownSelection.
