JComboBox, what listener when I need to catch a mouse click after a state (has not to be new) is selected?

Can't use an ItemListener because my JComboBox items are generated dinamica开发者_开发知识库lly so that would generate exceptions when the list is empty. I need to catch basically the state after a mouse click event on an item (the problem with MouseListener is that it catches the event even when I open the list of items in the JComboBox).

Try to use ActionListener.
