java - 防止 JMenuItem 在单击时关闭 JMenu

Question

我怎样才能做类似 this 的事情当我使用多个 LAF 时:

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

Answer 1

我这样解决了我的问题:

public class MyMenuItem extends JMenuItem {

    public MyMenuItem(String text) {
        super(text);
    }

    @Override
    protected void processMouseEvent(MouseEvent evt) {
        if (evt.getID() == MouseEvent.MOUSE_RELEASED  && contains(evt.getPoint())) {
            doClick();
            setArmed(true);
        } else
            super.processMouseEvent(evt);
    }

}
