菜单栏右侧的Swing菜单项 [英] Swing menu item on right of Menu Bar

问题描述

我有一个swing应用程序，并且我想在JFrame的菜单上添加一个Help MenuItem，但将其右对齐.
有任何想法吗 ?

I have a swing application and on the JFrame's menu I want to add a Help MenuItem, but have it Right justified.
Any ideas ?

Swing JMenuBar具有BoxLayout，我已经尝试过:

A Swing JMenuBar has a BoxLayout and I have tried:

menuItem = new JMenuItem("Help");
menuItem.setAlignmentX(Box.RIGHT_ALIGNMENT);
menuBar.add(menuItem);

菜单仅停留在左侧. 我也尝试过:

The menu just stays on the left. I have also tried:

menuBar.add(Box.createHorizontalGlue());  

按照Swing教程...，但这只是增加了一个空格.

as per the Swing Tutorial... but that just adds a space.

我正在使用Windows7.JDK 1.6.26

I am using Windows 7. JDK 1.6.26

如果执行此操作，则按照Java教程进行操作:

It works as per the Java Tutorial if I do:

    menuBar.add(Box.createHorizontalGlue());

    helpMenu = new JMenu("Help");
    menuBar.add(helpMenu);
    menuItem = new JMenuItem("Help");
    helpMenu.add(menuItem);  

但这不是我想要的.我只希望能够将帮助MenuItem添加到JMenuBar.现在，这将是我的后备.

But that is not what I am looking for. I just want to be able to add the help MenuItem to the JMenuBar. For now that will need to be my fallback.

推荐答案

尝试Component.setComponentOrientation()方法.

menuItem.setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT);
