问题描述
我有一个Java Swing应用程序，我想在Mac OS X上运行。我想使用正常的Mac复制/粘贴快捷方式将文本复制/粘贴到我的Java应用程序中的文本字段。
I have a Java Swing application that i want to run on Mac OS X. I want to use the normal Mac copy/paste shortcuts to copy/paste text to a text field in my Java application.
+ & + 是指令，但我想使用 + & + 。
+ & + does the trick but i want to use + & + instead. How can i do that?
推荐答案
如果您使用第三方L& F实现，可能不支持Mac的本机键盘快捷键。以下代码应在设置L& F之后恢复 JTextField 的Mac键盘快捷键：
If you're using a 3rd-party L&F implementation it probably doesn't support the Mac's native keyboard shortcuts. The following code should reinstate the Mac's keyboard shortcuts for JTextFields after setting the L&F:
InputMap im = (InputMap) UIManager.get("TextField.focusInputMap");
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_C, KeyEvent.META_DOWN_MASK), DefaultEditorKit.copyAction);
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_V, KeyEvent.META_DOWN_MASK), DefaultEditorKit.pasteAction);
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_X, KeyEvent.META_DOWN_MASK), DefaultEditorKit.cutAction);
当然，如果您检测到应用程序正在Mac上运行，您只需要执行此操作因此您不会影响其他操作系统的键盘映射。
Of course you'll only need to do this if you detect that the application is running on a Mac so that you don't affect the keyboard mappings for other OS's.
