TabItem close listener

[dato.java]

Hello,

I have several tabs and need to do some action when tab is being closed,but it does not work,i dont know why

                TabItem ti = new TabItem(id);
                ti.setClosable(true);

		ti.addListener(Events.Close, new Listener<BaseEvent>() {
			public void handleEvent(BaseEvent arg0) {
				com.google.gwt.user.client.Window.alert("");
			}

		});
		
		tabPanel.add(ti);

I use EXT GWT 2.2.3 and GWT 2.2.1 version

Set Events.BeforeRemove listener on the TabPanel, Try this instead :

tabPanel.addListener(Events.BeforeRemove, new Listener<TabPanelEvent>() {
	@Override
	public void handleEvent(TabPanelEvent evt) {
	     if(true){ // U decide what this condition should be
                 evt.setCancelled(true);
             }
	}
});

The containing component can detect closing of the tabitem or rather the event before removal from the tabpanel. My code is something like :

public void handleEvent(BaseEvent be) {
        try {            
            if (be instanceof TabPanelEvent && be.getType() == Events.BeforeRemove) {
                TabItem tabItem = ((TabPanelEvent) be).getItem();
                //  do your thing
            }
        }
        catch (Exception e) {
            // exception handling code
        }
}

BeforeClose : TabPanelEvent(tabPanel, item)
Fires before an item is closed by the user clicking the close icon. Listeners can cancel the action by calling BaseEvent.

You should see the API
