- 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.
