this one does the trick:

new PanelListenerAdapter() { public void onExpand(Panel panel) {} };

Hi all,

I'm trying to hook onto the event where the user clicks the little '+' button on one of the panels in an accordion.  Thus far I've been able to get my code listening to the click event of a panel inside the accordion, but this only gets triggered when the user clicks on the title area of the item.  What I'm really trying to achieve is to get a hook onto the expand event, so that I can execute some code whenever an item in the accordion is expanded, regardless of whether the user clicked the little '+' button or the title of the item.

Here's the code I'm currently using to hook onto the click ('panel' is a panel that has been added to the accordion):

panel.addListener(new ContainerListenerAdapter(){   public void onRender(Component component) {      panel.getEl().addListener("click", new EventCallback(){         public void execute(EventObject e) {            MessageBox.alert("Panel clicked");         }      });   } });

Any help is much appreciated.

Cheers, Bryce.
