Perhaps the worst thing is that back in the main Triton class, I have
code like this.
void setConnected(boolean isConnected) {
l_connected = isConnected;
if (l_connected) {
mi_login.setEnabled(false);
mi_logout.setEnabled(true);
} else {
mi_login.setEnabled(true);
mi_logout.setEnabled(false);
}
}
boolean isConnected() {
return(l_connected);
}
All this does is toggle the "connected" state, and enables/disables
menu items accordingly. I really, really don't like this design.

I assume that function public LoginDialog is the
constructor for class LoginDialog. I see Frame passed
as a parameter to the constructor, but I don't see
that you use it. What is it doing?

I wonder if the reference to the JFrame is for a

has both an 'owner' (one responsible for utimately

your
objects would need to reference the JFrame (is
this a
graphic frame?) unless it was for messaging (i.e.
"time to repaint your area!")
