How to interpret a checkbox state change (TreeGrid tri-state checkbox)

[Jolie]

Hi,

I found this very nice feature that creates a tri-state checkbox tree here http://www.smartclient.com/smartgwt/...#tree_checkbox

But how do i catch and interpret the state change event?

The SelectionChangedHandler is triggered but i cant get any usefull information from it.

treeGrid.addSelectionChangedHandler(new SelectionChangedHandler() {
         public void onSelectionChanged(SelectionEvent event) {
            //I want to know what item that changed state 
            //and what the new state is but i dont know how.
         }
      });

Best Regards,
Jolie

Should i be doing something else to catch these kind of events?

Is this a feature i can only access with the Enterprise version? Or does the Enterprise version make accessing this easier in some way?

The Event gives you the Record which can be used with ListGrid.isPartiallySelected() and related APIs.
