SectionItem expand event

[basis.cedric]

Hello,
I'm using SmartGWT 3.1p of 12/25/2012 (v8.3p_2012-12-25/PowerEdition Deployment) and like to know if there is a way to add an Handler for SectionItem to be notified when it is expanded. My use case is to lazy load a grid inside a closed section. If the user opens it, the content will be loaded.
I've tried to add a click handler, a title click handler, a show value handler and none of them were called.
How could I be notified when a section item is expanded?

Regards,
Cédric.

While we don't have an explicit notification method, you should be able to use the click handler. Here's an example:

    @Override
    public void onModuleLoad() {
        
        SectionItem testItem = new SectionItem();
        testItem.addClickHandler(new ClickHandler() {
            
            @Override
            public void onClick(ClickEvent event) {
                boolean open = ((SectionItem)event.getItem()).isExpanded();
                if (open) {
                    SC.say("Open");
                }
            }
        });
        // Initially collapsed
        testItem.setSectionExpanded(false);
        
        TextItem item1 = new TextItem();
        item1.setName("One");
        
        TextItem item2 = new TextItem();
        item2.setName("Two");
        
        TextItem item3 = new TextItem();
        item3.setName("Three");
        
        testItem.setItemIds("Two");
        
        DynamicForm testForm = new DynamicForm();
        testForm.setItems(item1, testItem, item2, item3);
        
        testForm.draw();
        
    }

I added a ClickHandler as you said and it's working well.
Don't know what I did wrong last time.
Thanks!
