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

    Default 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){
            this.main = c;
        public void someFunction(){
            //do something
