Я пытаюсь создать кнопку, которая переходит к следующему экрану, когда все счетчики имеют выбранные значения. Чтобы определить, когда счетчики имеют значения (дневные, часовые и минутные счетчики), я назначил значения для state для каждого счетчика. Большая часть кода работает, как и ожидалось, за исключением оператора if в коде kv, который я показал ниже.
Button:
background_color: 0, 0, 0, 1
size: (400, 130)
size_hint: (None, None)
pos_hint: {'right': 0.6, 'center_y': 0}
on_press:
root.hours_checking()
if day.state == hours.state == minutes.state == AmPm.state == 'True': \
root.manager.current = 'screen_three'
Эта часть кода, по-видимому, не выполняется по какой-то причине. Переход к экрану 3 не происходит.
if day.state == hours.state == minutes.state == AmPm.state == 'True': \
root.manager.current = 'screen_three'
Spinner:
id: day
size_hint: None, None
size: 100, 44
pos_hint: {'center': (.5, .5)}
text: 'Day'
values: 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'
on_text:
root.on_day_select(self.text)
state: 'True'
Spinner:
id: hours
size_hint: None, None
size: 100, 44
pos_hint: {'center': (.1, .5)}
text: 'Hour'
values: '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12'
on_text:
root.on_hours_select(self.text)
state: 'True'
Spinner:
id: minutes
size_hint: None, None
size: 100, 44
pos_hint: {'center': (.3, .5)}
text: 'Minutes'
values: '00', '15', '30', '45'
on_text:
root.on_minutes_select(self.text)
state: 'True'
Spinner:
id: AmPm
size_hint: None, None
size: 100, 44
pos_hint: {'center': (.4, .5)}
text: 'AM/PM'
values: 'a.m', 'p.m'
on_text:
root.on_AmPm_select(self.text)
state: 'True'
Вот весь мой код. Если это поможет решить мою ошибку.
