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...
Thanks

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");
}
}
