When a JFrame Is Closed Exit From an Application

[Sheenas]

Hello, I am working on the project in java and while making use of it, I want to do something from which when I will Close the frame it will simply exit from the application which I am working. So, if you are having any solution to achieve it, then please help me to get the solution. I am not able to get the solution for it.

Hello, you need to use the following properties for getting the solution in this problem:

• DISPOSE_ON_CLOSE
• DO_NOTHING_ON_CLOSE
• EXIT_ON_CLOSE
• HIDE_ON_CLOSE

Hey, I think if you simply make use of the code below then you will able to get the solution for your problem:

JFrame frame= new JFrame();
frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
frame.addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent we)
{
exitProcedure();
}
});

Hello, I have the small code below which will help you to achieve the thing which you want:

import javax.swing.JFrame;

public class Main
{
  public static void main(String[] argv) throws Exception
 {
    JFrame fr = new JFrame();
    int checker = fr.getDefaultCloseOperation();
    fr.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }
}

First thing you will need to do is to get the close operaton by default. For that use the code below:

JFrame frm = new JFrame();

Now you need to use the code line below:

int op = frm.getDefaultCloseOperation();

After this you just need to use the EXIT_ON_CLOSE property for exiting the window.

frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
