NAME

       XtOwnSelection, XtOwnSelectionIncremental, XtDisownSelection - set selection owner

SYNTAX

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

       Boolean XtOwnSelectionIncremental(Widget w, Atom selection, Time time, XtConvertSelectionIncrProc
              convert_callback, XtLoseSelectionIncrProc lose_callback, XtSelectionDoneIncrProc done_callback,
              XtCancelConvertSelectionProc cancel_callback, XtPointer client_data);

       void XtDisownSelection(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.

       The XtOwnSelectionIncremental procedure informs the Intrinsics incremental selection mechanism that the
       specified widget wishes to own the selection. It returns True if the specified widget successfully
       becomes the selection owner or False otherwise. For more information about selection, target, and time,
       see Section 2.6 of the Inter-Client Communication Conventions Manual.

       A widget that becomes the selection owner using XtOwnSelectionIncremental may use XtDisownSelection to
       relinquish selection ownership.

       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.
