JMenuItem显示左边的复选框，如何禁用它？

问题描述

我正在建立一个下拉菜单，它驻留在程序菜单栏，并弹出一个JPopupMenu如果JButton被点击。在JPopupMenu有多个JMenuItems。

但是，在每个JMenuItem它显示一个复选框！其格式如下：

我不认为它应该，并有明确的JCheckBoxMenuItem。

有人知道为什么一个复选框出现在JMenuItem中，如何禁用/删除它？

代码

  ImageIcon icon = ViewUtilities.createIcon（resource / gui / mainMenu.png，_buttonLength）; 
 setIcon（icon）; 
 
 JMenuItem menuItem = new JMenuItem（New Whiteboard）; 
 menuItem.addActionListener（new NewWhiteboardActionListener（））; 
 getMenu（）。add（menuItem）; 
 
 menuItem = new JMenuItem（Open ...）; 
 menuItem.addActionListener（new OpenFileActionListener（））; 
 getMenu（）。add（menuItem）; 
 
 menuItem = new JMenuItem（Preferences ...）; 
 menuItem.addActionListener（new PreferencesActionListener（））; 
 getMenu（）。addSeparator（）; 
 getMenu（）。add（menuItem）; 
 
 menuItem = new JMenuItem（Exit）; 
 menuItem.addActionListener（new ExitActionListener（））; 
 getMenu（）。addSeparator（）; 
 getMenu（）。add（menuItem）; 
  

其中 getMenu（）返回 JPopupMenu 。

谢谢！

编辑：我已解决问题。问题出在图书馆。我使用它
为TabbedPanel的自定义LAF。只要加载弹出菜单
，它也会注入 LAF。

因此，解决方案太过设定不要载入选单样式。

  LookAndFeelFactory.installJideExtension（
 LookAndFeelFactory.VSNET_STYLE_WITHOUT_MENU）;

I'm building a drop down menu which resides in program menu bar and pops up a JPopupMenu if a JButton gets clicked. In the JPopupMenu there are multiple JMenuItems.

However, beside every JMenuItem it shows a checkbox! Which looks like this:

I don't think it should, and there is explicit JCheckBoxMenuItem for that.

Does anyone know why a check box appears in a JMenuItem and how do I disable / remove it?

The code

ImageIcon icon = ViewUtilities.createIcon("resource/gui/mainMenu.png", _buttonLength);
setIcon(icon);

JMenuItem menuItem = new JMenuItem("New Whiteboard");
menuItem.addActionListener(new NewWhiteboardActionListener());
getMenu().add(menuItem);

menuItem = new JMenuItem("Open...");
menuItem.addActionListener(new OpenFileActionListener());
getMenu().add(menuItem);

menuItem = new JMenuItem("Preferences...");
menuItem.addActionListener(new PreferencesActionListener());
getMenu().addSeparator();
getMenu().add(menuItem);

menuItem = new JMenuItem("Exit");
menuItem.addActionListener(new ExitActionListener());
getMenu().addSeparator();
getMenu().add(menuItem);

where getMenu() returns a JPopupMenu.

Thanks!

Cheers,
Shuo

Edit: I've fixed it. The problem is on Jide library. I've used itfor a custom LAF of TabbedPanel. And it injects LAF for popup menustoo as long as it's load.

So the solution is too set it to don't load menu styles.

LookAndFeelFactory.installJideExtension(
  LookAndFeelFactory.VSNET_STYLE_WITHOUT_MENU);
