TwinColSelect get item value on click

Hello guys, I was wondering if it’s possible to get the value of an item which is clicked in one of the two boxes of the TwinColSelect component. I am not talking about selecting the items from left to right, but just clicking on the item and getting its value. I am using vaadin 7.

There’s no existing server-side API for that. You would need to create a client-side [Component Extension]
(https://vaadin.com/docs/v7/framework/gwt/gwt-extension.html) to get an event like that, I think.
