Максимизация панелей в Javafx

Question

Я играл и тестировал с JavaFX, но одной проблемой, с которой я столкнулся, было увеличение размера панели. Я установил размер области привязки, чтобы использовать вычисленный размер, но он никогда не изменяет размеры и ничего не делает. Моя панель является фиксированной и не может изменять размеры. Могу ли я что-нибудь сделать, чтобы изменить размер панели? Спасибо! Я проверил размеры моего макета, но они были исправлены, хотя я установил размеры на расчетный размер. Прямо сейчас мой проект имеет только файлы F XML и некоторые методы в классе контроллера, которые еще ничего не делают.
