Добрый день,
Я уже два дня пытаюсь решить эту проблему и в отчаянии, я ищу твою помощь. Я хочу показать график (используя matplotlib) в моем приложении tkinter (не открывая его в другом окне), и проблема в том, что при нажатии любой из кнопок панели инструментов, как только я пересекаю курсор мыши, линии графика , график исчезает на короткое время и появляется снова, но кнопки панели инструментов исчезают, пока я снова не пересекаю их курсором мыши. Поэтому, чтобы кнопка вернулась назад, я должен зачеркнуть ее и вычеркнуть кнопку.
Я заметил, что если я изменяю фоновое изображение (только цвет, помещенный в метку), исчезнувшие кнопки заменяются этим цветом. , поэтому кажется, что когда я пересекаю линии графика, все в Label, кроме графика, перекрывается фоном.
С уважением,
Владислав
