Hello Everyone:
I need some help with a GUI project.
What I want to do is when someone select the File Menu and chose New a Jpanel will open.
I have tried to write the code which is called class labelListener implements ActionListener. The Bold font is where I need help in...
Here is the code I have so far
public class GUIMenu extends JFrame {
Any help would be great
thanks

I need some help with a GUI project.
What I want to do is when someone select the File Menu and chose New a Jpanel will open.
I have tried to write the code which is called class labelListener implements ActionListener. The Bold font is where I need help in...
Here is the code I have so far
public class GUIMenu extends JFrame {
Code:
public GUIMenu() {
super("Menus");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Build first menu in the menu bar.
JMenuItem f1 = new JMenuItem("New");
f1.setMnemonic(KeyEvent.VK_N);
f1.getAccessibleContext().setAccessibleDescription(
"If this was working you could open a new file");
JMenuItem f2 = new JMenuItem("Open");
f2.setMnemonic(KeyEvent.VK_O);
[B]f2.addActionListener(new labelListener());//loads/sets the listener[/B]
JMenuItem f3 = new JMenuItem("Exit");
f3.setMnemonic(KeyEvent.VK_E);
f3.addActionListener(new exitListener());//loads/sets the listener
//Build second menu in the menu bar.
JMenuItem e1 = new JMenuItem("Copy");
e1.setMnemonic(KeyEvent.VK_C);
JMenuItem e2 = new JMenuItem("Cut");
e2.setMnemonic(KeyEvent.VK_X);
JMenuItem e3 = new JMenuItem("Paste");
e3.setMnemonic(KeyEvent.VK_P);
//Build third menu in the menu bar.
JMenuItem a1 = new JMenuItem("Close");
a1.setMnemonic(KeyEvent.VK_D);
a1.addActionListener(new exitListener());//loads/sets the listener
//Create the menu bar.
JMenuBar menubar = new JMenuBar();
//Build the first menu.
JMenu menu = new JMenu("File");
menu.add(f1);
menu.add(f2);
menu.addSeparator();
menu.add(f3);
menubar.add(menu);
//Build the Second menu.
JMenu menu2 = new JMenu("Edit");
menu2.add(e1);
menu2.add(e2);
menu2.add(e3);
menubar.add(menu2);
//Build the Third menu.
JMenu menu3 = new JMenu("Close the program");
menu3.add(a1);
menubar.add(menu3);
// prepare user interface
JTextArea edit = new JTextArea(8, 40);
JScrollPane scroll = new JScrollPane(edit);
BorderLayout bord = new BorderLayout();
setLayout(bord);
add("Center", scroll);
setJMenuBar(menubar);
pack();
setVisible(true);
}
//inner class Section used for exit on menu 3 for fun
class exitListener implements ActionListener {
public void actionPerformed(ActionEvent arg0) {
int x = JOptionPane.showOptionDialog(GUIMenu.this, "Exit Program?",
"Exit Request", JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE, null, null,
JOptionPane.NO_OPTION);
if (x == JOptionPane.YES_OPTION) {
GUIMenu.this.dispose();
}//close the if statement
}//close public void actionPerformed
}//close the class exitListener
[B]class labelListener implements ActionListener {
public void actionPerformed(ActionEvent arg0) {
String[] formats = { "Atom", "RSS 0.92", "RSS 1.0", "RSS 2.0" };
JPanel JPanelPane;
JPanel x = JPanelPane = new JPanel();
JLabel formatLabel = new JLabel("Output formats:");
rootPane.add(formatLabel);
JComboBox formatBox = null;
for (int i = 0; i < formats.length; i++)
formatBox.addItem(formats[i]);
rootPane.add(formatBox);
add(rootPane);
setVisible(true);
{
GUIMenu.this.dispose();
}[/B]
}
}
public static void main(String[] arguments) {
GUIMenu frame = new GUIMenu();
}
}
