ClosingWindow, Jframe Question

[ronnyjljr]

Okay here goes,

When the user closes the JFrame I want them to be prompted to confirm that they do want to close it.
I am listening for the WindowClosing event but I don't think that is correctly. If the window closing event is called, does that mean it is too late to stop it from closing?

More precisely, this code is executed but I have no clue how to stop the window from closing. Do I have to listen for a seperate event or is there something I can add here?

This is my code for the listener...

public void windowClosing(WindowEvent arg0)
{		
	if (JOptionPane.showConfirmDialog(null,"Are you sure you want to exit?","Exit?",JOptionPane.YES_NO_OPTION)==1)
	{			
		ShutdownSockets();
	} //END IF
} //End Window Closing

you'll have to do this first in your JFrame

setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE)

and then in the windowclosing method add setvisible(false) if you want to close it and do nothing or setvisible(true) when you want to close it.

Hi Chrissie1,

Thanks for the reply, I also had to add a System.exit(0) call to make sure the application shuts down. Your suggestions worked perfectly.

Thanks,
