如何在Java中创建隐藏菜单项的快捷方式 [英] How to make shortcut to invisible menu item in Java

问题描述

我最近在我的程序中添加了一个控制台对话框，以便更容易地捕获bug。目前可以通过JMenuItem访问它，并且键盘快捷键为Ctrl + L。

I've recently added a console dialog to my program to make catching bugs easier. This is currently accessible through a JMenuItem and has keyboard shortcut 'Ctrl+L'.

理想情况下我想保留此选项但是使菜单项隐藏/隐藏，因为我真的希望人们使用它，如果他们将内容复制给我，所以我可以调查一些事情。但是，当我将菜单项设置为不可见时，快捷方式也会停止工作。

Ideally I'd like to keep this option in but make the menu item hidden/invisible, because I only really want people to use it if they are copying the contents to me so I can investigate something. However, when I set the menu item to be invisible the shortcut also stops working.

这是我尝试过的：

    mntmViewLogs.setAccelerator(KeyStroke.getKeyStroke('L', KeyEvent.CTRL_DOWN_MASK));
    mntmViewLogs.setVisible(false);

谢谢！

推荐答案

您应该使用密钥绑定API： http：/ /docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html

You should use the key bindings API: http://docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html

将加速键不设置为菜单，而是设置为后面的操作menu：
getInputMap（WHEN_IN_FOCUSED_WINDOW）.put（
acceleratorKey，
actionname）;

Set accelerator key not to menu, but to the action behind the menu: getInputMap(WHEN_IN_FOCUSED_WINDOW).put( acceleratorKey, actionname);
