使用Nimbus LAF的Mac键盘快捷键 [英] Mac Keyboard Shortcuts with Nimbus LAF

问题描述

有没有办法在OS X上使用Nimbus LAF（外观和感觉），同时仍然可以使用 Meta 键进行剪切/复制/粘贴和选择所有操作？

Is there a way to use Nimbus LAF (Look And Feel) on OS X while still being able to use the Meta key for cut/copy/paste and select-all operations?

我目前在我的Swing应用程序的main方法中有以下代码，它根据操作系统更改了LAF（OS X的默认值，所有其他的Nimbus）：

I currently have the following code in my Swing app's main method, which changes up the LAF based on the operating system (default for OS X, Nimbus for all others):

if (!System.getProperty("os.name", "").startsWith("Mac OS X")) {
    try {
        for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
            if ("Nimbus".equals(info.getName())) {
                javax.swing.UIManager.setLookAndFeel(info.getClassName());
                break;
            }
        }
    } catch (ClassNotFoundException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (InstantiationException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (IllegalAccessException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    } catch (javax.swing.UnsupportedLookAndFeelException ex) {
        java.util.logging.Logger.getLogger(LicenseInspectorUI.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    }
}

我这样做是为了解决方法，因为Nimbus会覆盖键盘OS X上的剪切/复制/粘贴和select-all的快捷方式（ Meta 键与 Ctrl 键）。如果只是键盘快捷键没有被覆盖，我宁愿一直使用Nimbus。

I do this as a workaround because Nimbus overrides the keyboard shortcuts for cut/copy/paste and select-all on OS X (Meta key versus Ctrl key). I would prefer to use Nimbus all the time, if only the keyboard shortcuts weren't overridden.

推荐答案

使用 getMenuShortcutKeyMask（） 方法与 NimbusLookAndFeel 配合使用以启用⌘键，如此example 。另请参阅此相关答案。

Using the getMenuShortcutKeyMask() method works with NimbusLookAndFeel to enable the ⌘ key, as shown in this example. See also this related answer.

在特定情况下a JTextField ，您可以在键绑定。

In the particular case of a JTextField, you can use the mask in a key binding that evokes the original action.

int MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();
JTextField jtf = new JTextField("Test");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_A, MASK), "select-all");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_C, MASK), "copy");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_X, MASK), "cut");
jtf.getInputMap().put(KeyStroke.getKeyStroke(KeyEvent.VK_V, MASK), "paste");
