I have a "Exit" JMenu in JMenuBar (I set X as Mnemonic)
I wana exit (Sysytem.exit(0)) from my application when I click on Exit button OR when I press ALT+X. I dont want to use menuSelected() function of MenuListener
Please tell me which event I should use.
Thanks

Read the Swing tutorial on "How to Use Menus":
http://java.sun.com/docs/books/tutorial/uiswing/components/menu.html
It shows you how to use mnemonics.
I know that how to use Mnemonics in Menus
My main problem is related to event of Menus
Following events are not working:-
(i.e. Folowing r not solved my problem)->
actionPerformed()
menuSelected()
menuDeselected()
mouseClicked()
Probably best to post a Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour. This will be without the usual form funcuality, but rather just the menu function. You can find out more about this construct here:
url http://homepage1.nifty.com/algafield/sscce.html
i am also new to this stuff but if you would like to use some keyboard keys you can use something like this
public void keyPressed(KeyEvent e) {
int keyCode = e.getKeyCode(); //gets the user input for the key ex 'A' or 'B' or...
//now you can use your if / else execution
if(keyCode==KeyEvent.VK_CONTROL && keyCode==KeyEvent.VK_F3) //VK_CONTROL means "ctrl" or VK_SHIFT means "shift key"
//display the message in the textField that "YOu are right"
else {
//display the output "You are wrong"
}
}
Learn about keyevents like camickr posted a tutorial where you will learn more but why not just use the dispose() method if a user clicks on exit?
JMenuItem m = (JMenuItem)e.getSource();
if ( m == quitItem ) {
dispose();
.
.
.
if you're adding a JMenu for your 'Exit' it won't work the way you have described
Instead add a JMenuItem to your JMenuBar, but, as well as setting the Mnemonic,
set the accelerator
JMenuItem menu = new JMenuItem("Exit");
menu.setMnemonic('X');
menu.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_X,KeyEvent.ALT_DOWN_MASK));
hi petes1234
thanks for knowing me about SSCCE
as per advising u...
i m sending u my compilable code...
i know that how to set mnemonics with Menus and also providing short-cut keys to Menus
Actually I wants:
1. when I click by Mouse on a menu in Menu-Bar then System.exit(0)
2. when I press hot-key for menu (like ALT+X) then System.exit(0)
3. when I select this perticular menu using arrow-keys then after pressing enter key, System.exit(0)
Is all these things possible using one event?
If yes, then plz tell me. I have already checked then menuKeyPressed(), menuSelected(),menuDeselected(),and actionPerformed() functions..
If any one interested to solve my probs then please mail me at <gajeshtripathi@sangamflock.com> otherwise u can reply me using this forum
source is here...

Read the Swing tutorial on "How to Use Menus". It shows you how to do everything.
Menus are not designed to be used the way you want them to be used. You simply click on a Menu and a drop down list of JMenuItems is displayed. You add your Actions and Accelerators to the menu items, not the menu. This is how all standard applications are designed.
If you want to design a non-standard application, then you can try adding a JButton or JMenuItem directly to the menu bar.
PROB. IS SOLVED
hi camickr
Only u has understood my problem exactly and provide me better solution.
I m very Thankful to user: camickr.
Here is solution:-
javax.swing.JMenuItem exit;
exit=new javax.swing.JMenuItem("Exit");
exit.setMnemonic('x');
menuBar.add(exit);
exit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setVisible(false);
dispose();
System.exit(0);
}
});
But this will generate an runtime exception when we try to reach exit menu-item using arrow key in Menu-bar
so I will take exit JMenuItem in a JMenu
Nice to meet u
@OP: see comment below
exit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// remove setvisible and dispose no need because only system.exit(0) is needed.
setVisible(false);
dispose();
System.exit(0);
}
});
