current value of the selection.
|
|
.IP \fIdone_proc\fP 1i
|

Specifies the procedure that is called

interested in being called back.
|
|
.IP \fIlose_selection\fP 1i

called back.
|
|
.IP \fIselection\fP 1i

|
Specifies an atom that describes the type of the selection (for example,

Specifies the widget that wishes to become the owner or to relinquish ownership.
|
|
.SH DESCRIPTION
|
|
The
|
|
.B XtOwnSelection
|
|
function informs the \*(xI selection mechanism that a
|
|
widget believes it owns a selection.
|
|
It returns
|
|
.B True
|
|
if the widget has successfully become the owner and
|
|
.B 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.
|
|
.LP
|
|
The
|
|
.B XtOwnSelectionIncremental
|
|
procedure informs the Intrinsics incremental selection mechanism that
|
|
the specified widget wishes to own the selection.
|
|
It returns
|
|
.B True
|
|
if the specified widget successfully becomes the selection owner or
|
|
.B False
|
|
otherwise.
|
|
For more information about \fIselection\fP, \fItarget\fP,
|
|
and \fItime\fP, see Section 2.6 of the \fIInter-Client Communication
|
|
Conventions Manual\fP.
|
|
.LP
|
|
A widget that becomes the selection owner using
|
|
.B XtOwnSelectionIncremental
|
|
may use
|
|
.B XtDisownSelection
|
|
to relinquish selection ownership.
|
|
.LP
|
|
The
|
|
.B XtDisownSelection
|
|
function informs the \*(xI 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,
|
|
.B XtDisownSelection
|
|
does nothing.
|
|
.LP
|
|
After a widget has called
|
|
.BR 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
|
|
.B XtDisownSelection
|
|
finishes after the call to
|
|
.BR XtDisownSelection .
