This is e real newbie problem.
I created a JPanel :

public class P1 extends JPanel implements ActionListener {
some code
}

On a different file, but in the same dir, I have a JFrame:

public class F1 {
JFrame ditframe = new JFrame {
some code
}

I try to start the JFrame from the JPanel somewhere under:

public void actionPerformed(Action Event e) {
.....
}

How d I call the JFrame?


Probably by making ditframe an instance variable, providing a method in F1 that does "ditframe.setVisible(true);", then calling that method from P1 after instantiating F1.

If that doesn't make any sense to you then read this

Or if he extended JFrame with F1 like he extended JPanel with P1 then he wouldn't have to have a separate method to make F1 visible and he wouldn't need to create his own JFrame within F1 either.

That would make more sense. I assumed petoeter had some good reason for wanting to "start the JFrame" from within the JPanel's ActionListener.
In retrospect that seems unlikely.
