Copy shortcut links with ctrl key only in OSX Java application

Question

I created a small application using NetBeans 8.1 on OSX by following these steps:

• I created a new JForm using the Swing GUI forms category
• I added three menus:

• I added JDialog with text fields and linked it to the third menu ("TAnalyse").

In this JDialog, I need copy / paste functions for text fields. The problem is that copy / paste only works in this dialog box with "ctrl" + "c", "x" or "v", and not with the standard "cmd" osx.

I tried adding the following line of code to the JForm constructor, but it did not work:

KeyStroke stroke = KeyStroke.getKeyStroke(KeyEvent.VK_C, Toolkit.getDefaultToolkit().getMenuShortcutKeyMask());

: JDK7 OSX Yosemite. "". ( "", "" ) .

?

Update: GUI NetBeans (Swing GUI Forms → JDialog). JFrame JMenuItem GUI. - :

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);
    }
