XtOwnSelection(3Xt) XtOwnSelection(3Xt) NAME XtOwnSelection, XtOwnSelectionIncremental, XtDisownSelection - set se- lection owner SYNOPSIS Boolean XtOwnSelection(w, selection, time, convert_proc, lose_selec- tion, done_proc) Widget w; Atom selection; Time time; XtConvertSelectionProc convert_proc; XtLoseSelectionProc lose_selection; XtSelectionDoneProc done_proc; Boolean XtOwnSelectionIncremental(w, selection, time, convert_callback, lose_callback, done_callback, cancel_callback, client_data) Widget w; Atom selection; Time time; XtConvertSelectionIncrProc convert_callback; XtLoseSelectionIncrProc lose_callback; XtSelectionDoneIncrProc done_callback; XtCancelConvertSelectionProc cancel_callback; XtPointer client_data; void XtDisownSelection(w, selection, time) Widget w; Atom selection; Time time; ARGUMENTS Specifies the procedure that is to be called whenever someone requests the current value of the selection. 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. 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. Specifies an atom that describes the type of the selection (for example, XA_PRI- MARY, XA_SECONDARY, or XA_CLIPBOARD). Specifies the timestamp that in- dicates when the selection ownership should commence or is to be relin- quished. 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 wid- get has successfully become the owner and False otherwise. The widget may fail to become the owner if some other widget has asserted owner- ship at a time later than this widget. Note that widgets can lose se- lection 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 XtOwnSelectionInrcremental procedure informs the Intrinsics incre- mental 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 se- lection, target, and time, see Section 2.6 of the Inter-Client Communi- cation Conventions Manual. A widget that becomes the selection owner using XtOwnSelectionIncremen- tal may use XtDisownSelection to relinquish selection ownership. The XtDisownSelection function informs the Intrinsics selection mecha- nism 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 proce- dure will be called if a conversion that started before the call to XtDisownSelection finishes after the call to XtDisownSelection.
