Нарисовал доску шахматную, расставил фигуры и добавил парочку евентов.
Все старался сразу же делать по принципу MVC дабы набивать руку. Перечитал и сейчас и раньше десятки статей, вроде и принцип понимаю, а при программировании шаг влево, шаг вправо и тону.. :(
Так вот, вот черновой вариант трех классов, вот так вот сходу они мне написались.
1. Пожалуйста подкорректируйте как кто понимает это все?
2. И еще вопросик, припустим есть обычная форма - две кнопки и два поля для ввода - откуда высосать Model? Получается будет только интерфейс(View) и обработчик событий этой формы(Controller)?
3. И еще вопросик, тут вот мыслю подкинули(да я и сам понимаю), что такой код не есть хорошо...
1.
Object chekPiece = ((JLabel) (((JComponent) evt.getComponent()).getComponent(0))).getIcon();
Альтернатива? Создавать временные переменные - будет больше кода, но читабельней...
Спасибо за советы - вот три класса!
Да конечно, кто-то может лучшую идею предложить как код написать и так д.. но я спрашиваю о архитектуре.
