问题描述
有人可以向我解释您如何在kivy中更新小部件吗?我在这里有一个代码示例:
Can anyone explain to me how you update widgets in kivy? I have a code sample here:
class Game(Widget):
def __init__(self, **kwargs):
super(Game, self).__init__(**kwargs)
with self.canvas:
Color(*sky_color)
Rectangle(pos=(0, 0), size=self.size)
with self.canvas:
Color(*grass_color)
Rectangle(pos=(0,0), size=(800,75))
with self.canvas:
Label(text='Funky Chicken', font_size='50sp', pos=(360, 400))
with self.canvas:
Button(text='Play', font_size='20')
class FunkyChickenApp(App):
def build(self):
return Game(size=Window.size)
if __name__ == "__main__":
FunkyChickenApp().run()
这应该是游戏菜单,因此当您按下某些按钮时,某些标签和内容必须更改.
This is supposed to be a game menu so some labels and stuff have to change when you press some buttons.
编辑* 我的意思是我如何使用Kivy时钟
Edit* What i mean is how do I use Kivy clock
推荐答案
You need to bind actions to the buttons (the documentation has a few examples https://kivy.org/docs/api-kivy.uix.button.html).
即
button = Button(text='Play', font_size='20')
button.bind(on_press = do_something_you_want)
