推荐答案
您可以通过将窗口的on_request_close
与函数绑定来检查条件是否满足:
You can do it by binding the window's on_request_close
with a function to check if the conditions are met:
from kivy.app import App
from kivy.core.window import Window
from kivy.uix.label import Label
class Base(Label):
def __init__(self, **kwargs):
super(Base, self).__init__(**kwargs)
Window.bind(on_request_close=self.exit_check)
self.counter = 0
self.text = str(self.counter)
def exit_check(self, *args):
self.counter += 1
if self.counter < 5:
self.text = str(self.counter)
return True # block app's exit
else:
return False # let the app close
class SampleApp(App):
def build(self):
return Base()
if __name__ == "__main__":
SampleApp().run()
