XtDisownSelection()													       XtDisownSelection()

Name
  XtDisownSelection - indicate that selection data is no longer available.

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

Inputs
  w	    Specifies the widget relinquishing selection ownership.

  selection Specifies which selection the widget is giving up (usually XA_PRIMARY or XA_SECONDARY).

  time	    Specifies the timestamp that indicates when the request to relinquish selection ownership was initiated.

Description
  XtDisownSelection() informs the Intrinsics selection mechanism that the specified widget is to lose ownership of the specified selection as
  of the specified time.  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 XtConvertProc is not called even if a request arrives later with a timestamp during the
  period that this widget owned the selection.	However, its XtDoneProc will be called if a conversion that started before the call to XtDis-
  ownSelection() finishes after the call to XtDisownSelection().  See XtOwnSelection() for more information.

Usage
  Usually, a selection owner maintains ownership indefinitely until some other client requests ownership, at which time the Intrinsics selec-
  tion mechanism informs the previous owner that it has lost ownership of the selection.  However, in response	to  some  user	actions  (for
  example,  when  a user deletes the information selected), the application may with to explicitly inform the Intrinsics that it no longer is
  to be the selection owner by calling XtDisownSelection().

  When the selection changes hands because another client has claimed it (rather than as a result of  a  call  to  XtDisownSelection()),  the
  Intrinsics inform the application that it has lost the selection ownership by calling its XtLoseSelectionProc.

NAME

       XtOwnSelection, XtOwnSelectionIncremental, XtDisownSelection - set selection owner

SYNTAX

       Boolean XtOwnSelection(Widget w, Atom selection, Time time, XtConvertSelectionProc convert_proc, XtLoseSelectionProc lose_selection, XtSe-
	      lectionDoneProc 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 inter-
		 ested 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 own-
       ership 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.
