Editor.java – main class<\/strong><\/p>\npublic class Editor {\n public static void main(String[] args) {\n Model model = new Model();\n View view = new View(model);\n new Controller(model, view);\n }\n}\n<\/code><\/pre>\nView.java<\/strong><\/p>\npublic class View extends JFrame {\n\n private Model model;\n private JButton btn;\n\n public View(Model model) {\n this.model = model;\n this.btn = new JButton(\"Test\");\n }\n\n public void addViewControlListener(ActionListener al){\n btn.addActionListener(al);\n }\n}\n<\/code><\/pre>\nController.java<\/strong><\/p>\npublic class Controller {\n public Controller(Model model, View view) {\n view.addViewControlListener(new ViewControlListener(model, view));\n }\n}\n<\/code><\/pre>\nViewControlListener.java – implements ActionListener<\/strong><\/p>\npublic class ViewControlListener implements ActionListener {\n\n private Model model;\n private View view;\n\n public ViewControlListener(Model model, View view){\n this.model = model;\n this.view = view;\n }\n\n public void actionPerformed(ActionEvent e) {\n \/\/update model\n \/\/refresh view\n }\n\n}\n<\/code><\/pre>\nAs you can see I have the one place (Controller.java<\/code>) where I create listeners and add
\nthese to components in view. You created multiple instances of the same listeners and lost control.<\/p>\nAlso my ActionListener<\/code> (ViewControlListener.java<\/code>) holds instances of model and view, so it can update variables in model and refresh view.<\/p>\n
