пытается первое приложение Blackberry.
Он будет отображать данные дневника (в конце концов).
Я просто пытаюсь заставить вещи работать понемногу.
Я не могу заставить кнопки работать в симуляторе, т.е. я нажимаю на них, и ничего не происходит.
Любая помощь приветствуется.
Код приведен ниже (надеюсь, в хорошем формате - первый пост, поэтому извиняюсь, если нет).
