Я новичок в JAVA и в настоящее время создаю генеалогическое древо, однако у меня возникли некоторые проблемы.
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * '*' '' '' 'отображается в графическом интерфейсе, когда я вызывал CreateTree методы из familytree (содержат мой JTree) класс напрямую с инициализированным объектом person, однако, если бы я вызвал TreeCreation (новый jframe для ввода) класс для jframe только для приема входных данных от пользователя перед передачей объекта person в качестве параметра в CreateTree методы и последующим обновлением моего основного графического интерфейса, почему-то JTree не отображается.
Я попытался отладить, и я вижу, что мой JTree содержит эти объекты, но по какой-то причине он просто не отображается в главном интерфейсе. я потратил 3 дня, пытаясь выяснить, что заставляет его не показываться в графическом интерфейсе после использования другого класса для ввода. Любая помощь приветствуется. Пожалуйста, дайте мне знать, если это возможно, иначе я перестану пытаться исправить это и найду другой способ, поскольку мой срок подходит к концу.
