Клавиатурный модуль не работает в tkinter Gui

/ 10 марта 2020

Я хотел создать клавиатуру, клавиши которой были бы цветными, когда я нажимал клавишу на клавиатуре. В коде нет ошибок, но когда кнопка нажата, ничего не происходит: сейчас нет, если возможно сделать эту клавиатуру с этим модулем, или я сделал несколько ошибок. Пожалуйста, помогите мне.

Вам не нужна библиотека клавиатуры для этого.

Сначала давайте исправим ваш очень избыточный код. Вместо того, чтобы писать каждую кнопку по одному, мы можем делать это динамически c способом, основанным на списке символов. В то же время мы можем сохранить наши кнопки в списке, который мы можем использовать для обновления кнопок при нажатии.

С помощью bind() мы можем проверить, была ли нажата одна из клавиш, а затем обновить соответствующая кнопка в списке.

Связывая все нажатия клавиш и все отпускания клавиш, мы можем использовать метод, чтобы проверить, была ли одна из этих клавиш в нашем списке, и если это так, обновить кнопку при нажатии и отпускании клавиши.
