我正在研究一个需要撤消/重做功能的Java小程序。这是设置热键的代码(在Windows上很好用)。
我的问题是:如何在Mac上使用Command + Z?我应该只检查System.getProperty(“os.name”)还是有一个更优雅的选择?
private void setupUndoHotkeys() {
String UNDO = "Undo action key";
String REDO = "Redo action key";
Action undoAction = new AbstractAction() {
public void actionPerformed(ActionEvent e) {
undo();
}
};
Action redoAction = new AbstractAction() {
public void actionPerformed(ActionEvent e) {
redo();
}
};
getActionMap().put(UNDO, undoAction);
getActionMap().put(REDO, redoAction);
InputMap[] inputMaps = new InputMap[] {
getInputMap(JComponent.WHEN_FOCUSED),
getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT),
getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW),
};
for(InputMap i : inputMaps) {
i.put(KeyStroke.getKeyStroke("control Z"), UNDO);
i.put(KeyStroke.getKeyStroke("control Y"), REDO);
}
}
谢谢,
尼尔

没关系,我在这里找到了它http://www.devdaily.com/blog/post/jfc-swing/how-program-apple-command-key-keystroke-java-swing-mac-osx
在任何平台上都应该撤消此操作。
KeyStroke.getKeyStroke(KeyEvent.VK_Z, Toolkit.getDefaultToolkit().getMenuShortcutKeyMask())
