我应该使用什么听众? (Java) [英] What listener should I use? (Java)

问题描述

我想要一个定义是否选择了JMenuItem的侦听器.没有按下，只是突出显示.我不需要MouseOver侦听器，因为应该从键盘执行选择.我应该使用什么听众?在此先感谢:)

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 :)

推荐答案

我猜您将ChangeListener添加到每个JMenuItem的ButtonModel中.

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