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

someone requests the current value of the selection.

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.

the timestamp that indicates when the selection ownership should commence

- Specifies the widget that wishes to become the
owner or to relinquish ownership.
The XtOwnSelectionInrcremental 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

may use XtDisownSelection to relinquish selection ownership.
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.
