XtGetSelectionValue(Xt)
XtGetSelectionValue --
obtain selection values
Syntax
void XtGetSelectionValue(w, selection, target, callback, client_data, time)
Widget w;
Atom selection;
Atom target;
XtSelectionCallbackProc callback;
XtPointer client_data;
Time time;
void XtGetSelectionValues(w, selection, targets, count, callback,
closures, time)
Widget w;
Atom selection;
Atom *targets;
int count;
XtSelectionCallbackProc callback;
XtPointer* closures;
Time time;
Arguments
callback-
Specifies the callback procedure that is to be called when the
selection value has been obtained.
client_data-
Specifies the argument that is to be passed to the specified procedure
when it is called.
client_data-
Specifies the client data (one for each target type)
that is passed to the callback procedure when it is called for that target.
count-
Specifies the length of the targets and client_data lists.
selection-
Specifies the particular selection desired (either XA_PRIMARY or
XA_SECONDARY).
target-
Specifies the type of the information that is needed about the selection.
targets-
Specifies the types of information that is needed about the selection.
time-
Specifies the timestamp that indicates when the selection
value is desired.
w-
Specifies the widget that is making the request.
Description
The 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
XtGetSelectionValue is called;
in fact, it may be called before or after
XtGetSelectionValue returns.
The XtGetSelectionValues function is similar to
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
XtGetSelectionValue.
The callback is called once with the corresponding client data for each target.
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 XtGetSelectionValue repeatedly.
