How to use TreeTableEvents?

[seu31199113]

When I add a new Listener to a TreeTable, why the error:

The method handleEvent(TreeTableEvent) of type new Listener<TreeTableEvent>(){} must override a superclass method

been thrown out?

The sample code is following as:



final TreeTable table = new TreeTable(cm);
table.setAnimate(false);
//table.setBorders(false);
table.setWidth(cp.getWidth());
table.getStyle().setLeafIconStyle("icon-page");

final TreeTableBinder<FileModel> binder = new TreeTableBinder<FileModel>(table, store);
binder.setDisplayProperty("name");
loader.load(null);

table.setWidth(cp.getWidth());


table.addListener(Events.Expand, new Listener<TreeTableEvent>(){

@Override
public void handleEvent(TreeTableEvent be) {
// TODO Auto-generated method stub


}

});
