Question

我在OSX上使用Netbeans 8.1创建了一个小应用程序。它只包含两个菜单＆＃34; file＆＃34;和＆＃34;编辑＆＃34;。目的是稍后在编辑菜单中添加完整的复制/剪切/粘贴功能。我想使用Netbeans GUI构建器，但我遇到以下问题：

第一次尝试：

我使用Netbeans GUI构建器（Swing GUI Forms - ＆gt; JDialog）创建了一个小例子。我刚刚在JFrame中添加了一个菜单栏，在GUI构建器中添加了一个JMenuItem，并为构造函数添加了一些代码。结果是：

正如你所看到的，我得到一个文字＆＃39; meta＆＃39;而不是Apple键＆＃39;⌘＆＃39;。

源代码为NewJDialogGUI.java：

import java.awt.Toolkit;
import java.awt.event.KeyEvent;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.KeyStroke;
import javax.swing.text.DefaultEditorKit;

public class NewJDialogGUI extends javax.swing.JDialog {
    private static final int MASK
        = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();

    public NewJDialogGUI(java.awt.Frame parent, boolean modal) {
        super(parent, modal);

        initComponents();

        AbstractAction copyAction = new DefaultEditorKit.CopyAction();
        copyAction.putValue(Action.ACCELERATOR_KEY,KeyStroke.getKeyStroke(KeyEvent.VK_C, MASK));


        this.jMenuItem1.setAction(copyAction);
        this.jMenuItem1.setText("Copy");
        this.jMenuItem1.setMnemonic(KeyEvent.VK_C);

    }

第二次尝试：

我使用Netbeans GUI构建器（Swing GUI Forms - ＆gt; Application sample form）创建了另一个小例子。结果是：

与第一次尝试相同的结果。

第三次尝试：

最后，我使用Netbeans（空Java文件）创建了一个示例，其源代码略微修改自here。结果是：

源代码是：

import java.awt.EventQueue;
import java.awt.Toolkit;
import java.awt.event.KeyEvent;
import javax.swing.AbstractAction;
import javax.swing.Action;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JTextField;
import javax.swing.KeyStroke;
import javax.swing.text.DefaultEditorKit;

/**
 * @see https://stackoverflow.com/a/34830519/230513
 */
public class NewEmptyGUI {

    private static final int MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();

    private void display() {
        JFrame f = new JFrame("Test");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JMenuBar menuBar = new JMenuBar();
        JMenu menu = new JMenu("Edit");
        menu.setMnemonic(KeyEvent.VK_E);
        JMenuItem menuItem = new JMenuItem();
        AbstractAction copyAction = new DefaultEditorKit.CopyAction();
        copyAction.putValue(Action.ACCELERATOR_KEY,
                KeyStroke.getKeyStroke(KeyEvent.VK_C, MASK));
        menuItem.setAction(copyAction);
        menuItem.setText("Copy");
        menu.add(menuItem);
        menuBar.add(menu);
        f.setJMenuBar(menuBar);
        f.add(new JTextField(10));
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }


    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {

                new NewEmptyGUI().display();
            }
        });
    }
}

这是预期的结果，但整个菜单基础设施是手动编码的，这不是我的意图。我想使用Netbeans GUI Builder。你有什么提示吗？

我正在使用JDK7和OSX Yosemite。外观和感觉是＆＃34; Nimbus＆＃34;。我只粘贴示例代码或第1和第3次尝试，因为它是相当多的代码。

Answer 1

我找到了所述问题的解决方案。

解决方案1（更改外观）：

代码示例演示了如何在Netbeans创建的代码中替换“Nimbus外观”。它还将为剪贴板操作设置正确的键盘快捷键，例如copy＆amp;自动粘贴Apple键'⌘'而不是“Control-Key”：

public static void main(String args[]) {

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


    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new App_Avaprism().setVisible(true);
        }
    });

解决方案2：

如果你想留在“Nimbus”，事情变得更加困难。起初：我发现无法替换文本'meta'。至少您可能希望剪贴板快捷方式使用Apple键“⌘”。

对于您的主应用程序，将以下代码放入构造函数中：

int MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask();

InputMap im = (InputMap) UIManager.get("TextField.focusInputMap");
    im.put(KeyStroke.getKeyStroke(KeyEvent.VK_C, MASK), DefaultEditorKit.copyAction);
    im.put(KeyStroke.getKeyStroke(KeyEvent.VK_V, MASK), DefaultEditorKit.pasteAction);
    im.put(KeyStroke.getKeyStroke(KeyEvent.VK_X, MASK), DefaultEditorKit.cutAction);

不幸的是：如果您从此主应用程序启动其他模式对话框，则快捷方式将无效。在这种情况下，您可以尝试使用KeyEventDispatcher为整个应用程序建立击键的全局重定向。有关详细信息，请访问here和here。
