Python Kivy：添加背景循环

Question

I want to paste a background loop into my Python-Kivy script. The problem is, that I've got only a App().run() under my script. So, if I put a loop, somewhere in the the App-Class, the whole App stopps updating and checking for events. Is there a function name like build(self) , that's recognized by Kivy, and represents a main/background-loop?

If you don't know, what I'm talking about, feel free to ask.

Answer 1

In case you need to schedule a repeated activity in a loop, you can use Clock.schedule_interval() to call a function on a regular schedule:

def my_repeated_function(data):
    print ("My function called.")

Clock.schedule_interval(my_repeated_function, 1.0 / 30) # no brackets on function reference 
                                                       # call it 30 times per second

There is a lot more information on how to schedule events on a regular, conditional or one-time basis with Kivy's event loop here .
