how to add functionality in dialog window

[Mike John]

Hello, i am new to AWT.

created the login window.

Question is how to add the following

1) Dialog window should disappear when click on "X"
2) Dialog window should minimize when click on "-"
3) Dialog window should maximize when click on "="
4) Dialog window should disappear when click on "Cancel"

import java.awt.*;
 
public class LoginWindow extends Frame
{
     
    public LoginWindow(String s1)
    {
        super(s1);
        setBounds(300, 200, 325, 140);
         
        setLayout(new FlowLayout());
        setBackground(Color.GRAY);
         
        add(new Label("Username"));
        TextField tf1=new TextField(10);
        add(tf1);
         
        add(new Label("Password"));
        TextField tf2=new TextField(10);
        tf2.setEchoChar('*');
        add(tf2);
         
        Button bt1=new Button ("Login");
        bt1.setBackground(Color.gray);
        add(bt1);
         
        Button bt2=new Button ("Canel");
        bt2.setBackground(Color.gray);
        add(bt2);
         
    }
     
    public static void main (String []arg)
    {
        Frame myframe=new LoginWindow("Login Window");
        myframe.setVisible(true);
                 
    }
 
}

Welcome to JavaRanch!

Are you sure you want to be using AWT? Swing succeeded AWT about 15 years ago for Java GUI development.

For your questions:

1. By X, do you mean the X close link in the upper right corner of the Frame? If so, I don't remember.
2. Use a KeyListener.
3. The same KeyListener as 2.
4. An ActionListener.

Those aren't detailed answers I know, but they point you in the right direction. You should give it your best try, and if you get stuck somewhere, we'll be here to answer any more specific questions you might have.

If you have a chance, please see ShowSomeEffort (⇐Click) from the JavaRanch FAQ.

in my experience, close, minimize and maximize work automatically when you extend JFrame

[Greg Charles]

Really? I remember having to implement a WindowListener to close a JFrame, but the exact recommended procedure kept changing, and then I stopped working with Swing. However, Mike is using and old-old-school AWT Frame. I really can't remember how those worked at all.

I think it is the same: you add a window listener to the frame, and in its closing or closed methods you put the appropriate code to shut down the app.

[Rob Camick]

JFrame frame = new JFrame(...);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

I think the default is "HIDE_ON_CLOSE".
