Thread: Popup menu in diffrent class then main Applet, how to repaint()?

In an attempt to better organise my code, I decided to have a main class,

public class MainClass extends Applet implements MouseListener, MouseMotionListener

and a second DrawMenu class,

public class DrawMenu extends PopupMenu implements MouseListener, MouseMotionListener, ActionListener

And it works perfect, except that after issuing a command in the menu, I need a repaint() in MainClass... ofc I can't create an instance of MainClass in DrawMenu, can't call MainClass.repaint() as it is not static... so I'm kind of stuck. Is there a proper way to do this, or do I have to put them in the same class?

Pass a reference to your DrawMenu class with your MainClass in the constructor. Then within DrawMenu you can call instance methods from the MainClass reference
Something like this:

public class DrawMenu...{
    private MainClass main = null;
    public DrawMenu(MainClass c){
        super();
        this.main = c;
    }
    public void someFunction(){
        //do something
        main.repaint();
    }
}
