Я могу предоставить весь мой код, если это поможет в решении проблемы, но я считаю, что это влияет только на один класс, его можно решить здесь, чтобы упростить проблема.Ни setContentPane(), ни getContentPane(). Add() works
У меня есть проект пасьянса (помните имя пакета/класса, это была пробная версия и ошибка, и я не удалял старые проекты), который отказывается принять класс GameArea, который у меня есть, который расширяет JPanel. GameArea отлично работает в своем отдельном экземпляре, где класс тестера работает только с JPanel на JFrame. Этот класс тестера использует setContentPane (newGame), чтобы добавить его в JFrame.
В следующем классе ни getContentPane(). Add (newGame), ни setContentPane (newGame) успешно добавляет игру в фрейм. Этот класс устанавливает главное меню с двумя кнопками. Первый из них берет на экран Start New Game, а затем кнопку, которая должна начать игру либо:
1) показывают только зеленый экран, если getContentPane() добавить (NewGame) используется
.2) покажите нажатой кнопку «Начать новую игру», а затем замерзайте на экране «Начать новую игру», если используется setContentPane (newGame). Это разочаровывает, потому что getContentPane(). RemoveAll() вызывается до этого ... Однако, используя это меню, я могу вернуться в главное меню и все еще работать в этом бесконечном цикле замораживания и исправления.
Я подозреваю, потому что я не знаю достаточно о свинговых занятиях, но что-то не хватает. Любая помощь очень ценится, так как мне нужно сделать это за 2 дня.
