Вопрос:
Как изменить цвет кнопки, когда я нажимаю кнопку?
from kivy.app import App from kivy.uix.widget import Widget from kivy.properties import StringProperty class TestWidget(Widget): back_color = StringProperty('') back_color = (0.4, 0.4, 0.4, 1) def __init__(self, **kwargs): super(TestWidget, self).__init__(**kwargs) def crick(self): self.back_color = (175/255,238/255,238/255,1) class TestApp(App): def __init__(self, **kwargs): super(TestApp, self).__init__(**kwargs) if __name__ == '__main__': TestApp().run() TestWidget: lt;TestWidgetgt;: BoxLayout: Label: canvas.before: Color: rgba: root.back_color Rectangle: pos: self.pos size: self.size id: label1 text: "Color" Button: id: button text: "Button" on_press: root.crick() Ответ №1:
Я использую свойство ListProperty.
from kivy.properties import ListProperty ... back_color = ListProperty([0.4, 0.4, 0.4, 1]) ... self.back_color = [175/255,238/255,238/255,1]
