Question

this might sound like a beginers question
i have a main class which extends jframe i called the frame graphicsframe i have also decleared, a jpanel inside
this class.
but how do i extend that JPanel in another class i know you can use graphicsframe.panel to change the methods. but then i have to declear all of the methods using graphicsframe.panel.

Answer 1

to extend a JPanel you simply, ... extend it:
public class MyPanel extends JPanel
  // you'll need a constructor or a few in here plus any override and new methods
}I try to avoid extending JPanels, JFrames, and whatnot unless I'm going to change the basic behavior of the component, most commonly to override the paintComponent of a JPanel so I can draw in it.
By the way, what is to "declear"?
One more point: you probably should post Swing questions in the Swing forum (but please don't do this now. Continue on with this thread and please don't cross-post).
