powerOn, а как быть если всё происходит в дилоговом окне. Он после метода вообще перестаёт реагировать.  А мне нужно в него ещё строчки писать. А код после setVisible(true) начинает выполнятся после закрытия JDialog. Наверное предоставлю исходник. Это окно аутентификации пользователя в которое я решил впихнуть ещё и статус загрузки файлов. Сорри реально много левого кода для понимания проблемы. Просто некогда переделывать. | Код |

Кстати у Хорстмана пишется что методы компонентов Swing должны вызыватся только из потока доставки событий. А так как на практике организовать такой поток нереально, то он вызывает метод actionPerformed() таймера Swing который периодически опрашивает соответствующий поток и обновляет окошко. В том то и вопрос, безопасно ли воспользоватся просто Thread.sleep(); ? |
