- 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 (that is, primary or 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.
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.
