What listener should I use? (Java)

问题

I want a listener that defines if a JMenuItem was selected. Not pressed, but just highlighted. I don't need MouseOver listener, because the selection is supposed to be performed from keyboard. What listener should I use? Thanks in advance :)

回答1:

I would guess you add a ChangeListener to the ButtonModel of each JMenuItem.

回答2:

You should use addActionListener.
