[ravi v kumar]

my question is

i am planing to develop small application using swings

in which, i place the jmenu in the main frame which contains
Menu->Login
->Logout(initially disabled)
->Exit
Operations(initially disabled)
-> my operations related to the application

when the user clicks login
and opening a new frame which contains the userid and password to enter
and after entering the user has to submit

i am validating the userid and password after that if he is valid user

hi,

you have to register the menu entry "logout" at the ActionListener. In method actionPerformed(Event e) you have to open the log in frame or the login dialog.

 
 
// must be defined as global private variable 
JFrame loginFrame; 
//must be defined in your constructor
login.addActionListener(this);
 
public void actionPerformed(Event e)
{
   Object a = e.getSource();
   if (a==login)
   {
      loginFrame = new JFrame()
      JPanel panel = new JPanel();
      //add your textfields and buttons to panel
      //add an ok Button 
      ok.addActionListener(this);
    }
   if (a==ok){
     loginFrame.dispose();
    }
 
} 
 

hope this may help

for getting the password look up the sun tutorial under how to use JPasswordField

for getting username you have to take the getText() method on your JTextField
