XtGetSelectionValue(3Xt)      SDK X11 R4.11MU05     XtGetSelectionValue(3Xt)


NAME
       XtGetSelectionValue, XtGetSelectionValues - obtain selection values

SYNTAX
       void XtGetSelectionValue(w, selection, target, callback, clientdata,
       time)
             Widget w;
             Atom selection;
             Atom target;
             XtSelectionCallbackProc callback;
             XtPointer clientdata;
             Time time;

       void XtGetSelectionValues(w, selection, targets, count, callback,
       clientdata, time)
             Widget w;
             Atom selection;
             Atom *targets;
             int count;
             XtSelectionCallbackProc callback;
             XtPointer clientdata;
             Time time;

ARGUMENTS
       callback  Specifies the callback procedure that is to be called when
                 the selection value has been obtained.

       clientdata
                 Specifies the argument that is to be passed to the
                 specified procedure when it is called.

       clientdata
                 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 becaues the ownership of the selection
       cannot change in the middle of the list, as would be when calling
       XtGetSelectionValue repeatedly.
