Мне просто нужно получить данные, которые хранятся в json отформатированном файле, для отображения с соответствующими полями просмотра, которые находятся в файле ui. Я нашел одно решение, но оно работает только с Qwidget, а не с объектом Qmainwindow. Я смог заставить его работать, создав подкласс Qtreeview в виде списка и перезаписав метод addItem. Кажется, я не могу заставить его работать и загружать данные из файлов json для отображения. доход.db содержит данные отчета о прибылях и убытках, которые необходимо прочитать для заполнения объекта treeview yield_view, который находится в файле ui. Конечно, приветствуется любая помощь.

Ниже находится файл financial.ui.
