Как отделить группы QRadioButton для разных таблиц

Рейтинг: 1Ответов: 1Опубликовано: 24.02.2023

Сам вопрос взял своё начало здесь: выделение строк по клику на строку и саму кнопку.

Образовалась в дальнейшем проблема при попытке увеличить количество таблиц (до 3 и более) - при нажатии по строке на любой таблице, видимо, из-за общедоступного self.row_selected и общей для всех таблиц self.button_group, объявленных в конструкторе и методе соответственно, выделение также меняется и в последней, куда вставлялись radioButton. (Стоит отметить, что при клике на саму кнопку в любой из таблиц всё работает верно, как планируется и при клике на строку).

Я пытался менять глобальные переменные, делать self.cell_row анонимной(лямбда-ф-ией) и передавать в неё флаги (из какой таблицы вызывается метод) - это всё не увенчалось успехом.

Как всё-таки обойти это и заставить работать клик по строке любой из таблиц так же, как клик по кнопке любой из таблиц?

Первые 2 скрина - клики по кнопкам таблицы (сохраняется выделение и отмеченные кнопки). Последний скрин - клики по строкам всех таблиц, кроме последней (меняются выделения, и отмечается rb только в последней таблице)

Клик по кнопке 1-ой таблицы Клик по кнопке 2-ой таблицы Клик по строке 1-ой таблицы
