Help GUI select and keystroke

[nomad]

I need help with JcomboBox
When and User select the Exit in the File box it will the
//inner class
class exitListener implements ActionListener {
...
}
which it open a window asking them if they want to close the program.

I have a statement
filemenu.setMne monic(KeyEvent. VK_X);
But the setMnemonic(Key Event .VK_X) is wrong.
Also I want to be able to drag down and select Exit.
Can someone please help me on this.



Here is my code...

class MyFrame extends JFrame {
    String[] file = { "New", "Open", "Exit" };//items for file
    String[] edit = { "Cut", "Copy", "Paste" };//items for edit
    JComboBox filemenu = new JComboBox();
    JComboBox editmenu = new JComboBox();
 
 
    public MyFrame(String title) {
        super(title);
        this.setSize(250, 250); //sets the size for the frame
        this.setLocation(200, 200);//location where frame is at
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        // setup contents
        makeComponents();
        initComponents();
        buildGUI();
 
        // display
        this.setVisible(true);
    }
 
    private void makeComponents() {
 
        JPanel pane = new JPanel();
//        file menu section
        filemenu = new JComboBox();
        JLabel fileLabel = new JLabel();
        pane.add(fileLabel);
        for (int i = 0; i < file.length; i++)
            filemenu.addItem(file[i]);
        pane.add(filemenu);
        add(pane);
        setVisible(true);
 
//edit menu section
        editmenu = new JComboBox();
        JLabel editLabel = new JLabel();
        pane.add(editLabel);
        for (int i = 0; i < edit.length; i++)
            editmenu.addItem(edit[i]);
        pane.add(editmenu);
        add(pane);
        setVisible(true);
    }
 
    private void initComponents() {
 
        filemenu.addActionListener(new exitListener());
    }
 
 
    //inner class
    class exitListener implements ActionListener {
        public void actionPerformed(ActionEvent arg0) {
 
                int x = JOptionPane.showOptionDialog(MyFrame.this, "Exit Program?",
                                "Exit Request", JOptionPane.YES_NO_OPTION,
                                JOptionPane.QUESTION_MESSAGE, null, null,
                                JOptionPane.NO_OPTION);
                if (x == JOptionPane.YES_OPTION) {
                        MyFrame.this.dispose();
                }
 
        }
}
 
 
 
 
    private void buildGUI() {
        Container cont = this.getContentPane();// set gui components into the frame
        this.setLayout(new FlowLayout(FlowLayout.LEFT));// Comp are added to the frame
        cont.add(filemenu);
        cont.add(editmenu);
    }
 
    // / inner classes
 
}
 
 
 
public class ButtonFrame {
 
    public static void main(String[] args) {
 
        MyFrame f1 = new MyFrame("This is my Project for GUI");
    }
 
}

Thanks

Your filemenu isn't a menu at all, it's a JCombobox. Have a look at the JMenu
and [b/JMenuItem[/b] classes; they make up the parts of your drop down menus.
Those classes implement the mnemonics methods and a bit more.

kind regards,
