NAME
XtGetSelectionValue, XtGetSelectionValues - obtain selection values
SYNTAX
void
XtGetSelectionValue(Widget w, Atom selection, Atom
target, XtSelectionCallbackProc callback, XtPointer
client_data, Time time);
void
XtGetSelectionValues(Widget w, Atom selection, Atom *
targets, int count, XtSelectionCallbackProc callback,
XtPointer client_data, 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 (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.
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.
