void XtDisownSelection(Widget w, Atom selection, Time time); ARGUMENTSconvert_proc
Specifies the procedure that is to be called when-
ever 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 when-
ever 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 theselection (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 X Version 11 Last change: libXt 1.0.8 1 XT FUNCTIONS XtOwnSelection(3xt) owner if some other widget has asserted ownership at a timelater than this widget. Note that widgets can lose selec-
tion 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 thelose_selection procedure is not called if the widget fails
to obtain selection ownership in the first place.The XtOwnSelectionIncremental procedure informs the Intrin-
sics incremental selection mechanism that the specified wid-
get wishes to own the selection. It returns True if the specified widget successfully becomes the selection owner orFalse otherwise. For more information about selection, tar-
get, and time, see Section 2.6 of the Inter-Client Communi-
cation Conventions Manual.A widget that becomes the selection owner using XtOwn-
SelectionIncremental may use XtDisownSelection to relinquish selection ownership.The XtDisownSelection function informs the Intrinsics selec-
tion mechanism that the specified widget is to lose owner-
ship of the selection. If the widget does not currently own the selection either because it lost the selection orbecause it never had the selection to begin with, XtDisown-
Selection 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.SEE ALSO
