Why are my JFrames closing?

Hi All

I'm trying to create my own instant messenger and have come across a problem. I have a log in form, when the user enters their name. Once they click 'Log In', another window opens displaying the users that are currently online. My problem arises when I want to close the log in form. When I close this the other window that displays the online users also closes. Does anyone know why this happens??

Thanks in advance.

What do you think the indicated line does?



Having said this, I'll also say that perhaps the login window ought to be a dialog and not a JFrame. Then this would be a moot issue.

Much luck!

Why not you try DISPOSE_ON_CLOSE or HIDE_ON_CLOSE because EXIT_ON_CLOSE calls Syste.exit(0) and exits the whole application. Dispose_on_close will only close the whole program when there are no active threads running and Hide_on_close will just hide your log-in window. Like what pete stein said why not try JDialog, its more relevant for the current situation.
