By 'kill the event' do you mean you want to intervene in the event dispatching and prevent other listeners from being notified? Somehow abort the handling of the event?

Why use a combo box if you don't want it to drop the list?
However, you may be able to use the consume method of some event classes. However, if the combo box uses event listeners to handle the drop list, it would be processed before ny listeners you can register. Ma need to sub-class JComboBox and intervene in the processEvent method.
