JMenuItem显示左边的复选框，如何禁用它？ [英] JMenuItem shows checkbox on the left, how to disable it?

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 Jide 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 it for a custom LAF of TabbedPanel. And it injects LAF for popup menus too 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);
