How do I go about setting a JFrame class relative to another JFrame class?

I know that if I create a JFrame in the same class as the one I want to center I call setLocationRelativeTo(this), but due to the class getting long I cut it down into smaller JFrame classes.

So far i'm having to use setLocationRelativeTo(null) to center it but this is not very good when I want the JFrame that is popping up to be ontop of the main JFrame.

JFrame class? I think you mean JFrame _instance_. – ApproachingDarknessFish Apr 21 '13 at 23:07
Yeah sorry I meant JFrame instance. – NextGenHen Apr 21 '13 at 23:16

You shouldn't have multiple frames in your application. For a secondary window you should use a JDialog. See: http://stackoverflow.com/questions/9554636/the-use-of-multiple-jframes-good-bad-practice. Then you just use `dialog.setLocationRelativeTo(frame);` – camickr Apr 21 '13 at 23:17

Thank you, I'll implement a dialogue instead. – NextGenHen Apr 21 '13 at 23:19
http://docs.oracle.com/javase/6/docs/api/java/awt/Component.html#getLocationOnScreen() set it relative to this. But I agree on multiple popups, too annoying for the user. – arynaq Apr 22 '13 at 14:29
