.SH DESCRIPTION
|
|
The
|
|
.B XtGetSelectionValue
|
|
function requests the value of the selection that has been converted to
|
|
the target type.
|
|
The specified callback will be called some time after
|
|
.B XtGetSelectionValue
|
|
is called;
|
|
in fact, it may be called before or after
|
|
.B XtGetSelectionValue
|
|
returns.
|
|
.LP
|
|
The
|
|
.B XtGetSelectionValues
|
|
function is similar to
|
|
.B XtGetSelectionValue
|
|
except that it takes a list of target types and a list of client data
|
|
and obtains the current value of the selection converted to each of the targets.
|
|
The effect is as if each target were specified in a separate call to
|
|
.BR XtGetSelectionValue .
|
|
The callback is called once with the corresponding client data for each target.
|
|
.B XtGetSelectionValues
|
|
does guarantee that all the conversions will use the same selection value
|
|
because the ownership of the selection cannot change in the middle of the list,
|
|
as would be when calling
|
|
.B XtGetSelectionValue
|
|
repeatedly.
