catch change on SelectItem

[rottem]

I am using SmartGwt 3.0, SmartClient Version: 8.2/LGPL Development Only (built 2011-12-05)
On FF11 and IE8

I have a SelectItem with

setMultiple(Boolean.TRUE);
setMultipleAppearance(MultipleAppearance.PICKLIST);

I want to add some behavior that happens when the drop down list is closed, i.e. only when the user finishes selecting the elements from the picklist, will the function be called. How can I do that?
Thanks

Is there any way to do this?
Thanks

Try

SelectItem selectItem = new SelectItem();

selectItem.addChangedHandler(new ChangedHandler() {

		@Override
		public void onChanged(ChangedEvent event) {

			SC.say("Look, I'm doing something!"); 

		}

	});

Thanks for your reply.

This handler gets called after every selection of element in the multiple pick list. I don't want to know every click he makes inside the pick list.

I want to catch the close of the pick list, after the user finished to make his changes.

How would you know when the user is done ? You perhaps need to have a button which he clicks on when he is done and use the click handler of that button to do the job you desire.

Interested to know if there is an answer to the original question though.

I think this is not possible.

As far I see, you are notified every time the users selects or unselects an entry (trough the ChangedHandler()).

I agree we could have some sort of handler to be notified when the user clicks the down arrow.

I would try using CheckBoxItem as a workaround.
