.IP \fIrequestor\fP 1i
|
|
Specifies the widget making the request.
|
|
Must be of class Core or a
|
|
subclass thereof.
|
|

|
|
Specifies the particular selection desired.
|
|
.IP \fItime\fP 1i
|
|
Specifies the timestamp to be used in making the request.
|
|
.SH DESCRIPTION
|
|
When
|
|
.B XtCreateSelectionRequest
|
|
is called, subsequent calls to
|
|
.B XtGetSelectionValue
|
|
and
|
|
.B XtGetSelectionValueIncremental
|
|
with the requestor and selection as specified to
|
|
.B XtCreateSelectionRequest
|
|
will be bundled into a single selection conversion request with
|
|
multiple targets.
|
|
The request is actually initiated by calling
|
|
.BR XtSendSelectionRequest .
|
|
.LP
|
|
When
|
|
.B XtSendSelectionRequest
|
|
is called with a value of \fIrequestor\fP and \fIselection\fP matching
|
|
a previous call to
|
|
.BR XtCreateSelectionRequest ,
|
|
a selection conversion request is actually sent to the selection owner.
|
|
If a single target request is queued, that request is made.
|
|
If multiple
|
|
targets are queued they are bundled into a single request with the
|
|
target MULTIPLE using the specified timestamp.
|
|
As the conversions are
|
|
made, the callbacks associated with each
|
|
.B XtGetSelectionValue
|
|
and
|
|
.B XtGetSelectionValueIncremental
|
|
are invoked in turn.
|
|
.LP
|
|
Multi-threaded applications should lock the application context before
|
|
calling
|
|
.B XtCreateSelectionRequest
|
|
and release the lock after calling
|
|
.B XtSendSelectionRequest
|
|
to ensure that the thread assembling the request is safe from interference
|
|
by another thread assembling a different request naming the same widget
|
|
and selection.
|
|
.LP
|
|
When
|
|
.B XtCancelSelectionRequest
|
|
is called, any requests queued since the last call to
|
|
.B XtCreateSelectionRequest
|
|
are cleaned up.
|
|
Subsequent calls to
|
|
.BR XtGetSelectionValue ,
|
|
.BR XtGetSelectionValues ,
|
|
.BR XtGetSelectionValueIncremental ,
|
|
and
|
|
.B XtGetSelectionValuesIncremental
|
|
will not be deferred.
