Проблема с GUI - макет действует странно

Question

У меня есть эта проблема. Когда я пытаюсь изменить свой графический интерфейс в панели panelRight, ничего не происходит. Он остается неизменным. Если вы посмотрите на мой MouseListener для моего «memberTable», он должен добавить панель справа, но когда я попытаюсь сделать это с помощью GridBagLayout, ничего не произойдет или добавит информацию, которую я хочу, но не флажок. Что я делаю не так? Мне действительно нужно решить эту проблему, прежде чем двигаться дальше.

Answer 1

Необходимо повторно проверить/перекрасить панель после этих изменений.

panelRight.revalidate(); 
panelRight.repaint();
