Как сделать, чтобы выделение Combobox заполняло поля ввода на tkinter?

/ 10 января 2020

Я новичок в tkinter, но я не знаю, что делаю неправильно, я уже определил функцию для атрибутов, которые будут внутри ящиков ввода, но известные появляются после того, как я запустил код. то есть Как связать выпадающий список выбора, чтобы он мог автоматически заполнять соответствующие поля ввода из класса сконструированного транспортного средства?

Я вижу две основные проблемы

  1. вы забыли некоторые StringVar переменные - ie. NoofDaysRenting и InvoiceID

  2. вы забыли использовать textvariable= для назначения StringVar на Entry - ie. 

     self.txtKmL = Entry(..., textvariable=self.KmL, ...)

, поэтому он не обновляет Entry при обновлении StringVar

кода после других изменений.

Он имеет textvariable= только в двух Entry, потому что для меня слишком много работы.

Я сделал некоторые изменения:

  • использование self.myvar вместо self.var1, потому что это должен быть StringVar, а не IntVar
  • , установить переменную NoofDaysRenting с фиктивным значением "22222", в противном случае у меня была ошибка
  • передать аргумент event в вашу функцию Vehicle, чтобы правильно связать его с списком
  • У меня было 2 строки обновите значение txtWeeklyCost, я позволю вам сделать то же самое для всех остальных полей ввода

И я советую вам очистить код, выполняя несколько классов, а не весь код в init function:)
