如何在 JPopupMenu 中更改字体大小

  • 772

我添加了字体大小，但没有改变。

btnUser.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {

            int x = btnUser.getX();
            int y = btnUser.getY() + btnUser.getHeight();
            JPopupMenu jPopupMenu = new JPopupMenu();
            jPopupMenu.setFont(new Font("Tahoma", Font.PLAIN, 20));

            jPopupMenu.add(new AbstractAction("Exit") {

                private static final long serialVersionUID = 1L;

                @Override
                public void actionPerformed(ActionEvent e) {
                    System.exit(0);                     
                }
            });
            jPopupMenu.show(panel, x, y);
        }
    });

    据我所知，popupMenu由menuItem组成，它们已经可以设置font。尝试这样的事情：

    //...
JPopupMenu jPopupMenu = new JPopupMenu();

JMenuItem item;

popup.add(item = new JMenuItem("Первый"));
item.setFont(new Font("Tahoma", Font.PLAIN, 20));
popup.add(item = new JMenuItem("Второй"));
item.setFont(new Font("Arial", Font.PLAIN, 15));
//...

  2. 做成这样。

    JMenuItem mntmExit = new JMenuItem("EXIT");
mntmExit.setFont(new Font("Tahoma", Font.PLAIN, 20));
mntmExit.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        System.exit(0);
    }
});
jPopupMenu.add(mntmExit);
