Изменение свойства kivy из другого потока
Я экспериментирую с небольшим количеством кода. Я попытался изменить свойство kivy (text_colour) из протектора, созданного с помощью lib. Программа работает нормально, но поток не меняет свойства.
Я также попытался создать метод в классе, который получает значение в качестве аргумента, что также не удалось.
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import ListProperty
import threading
import random
import time
def zaaa():
import time
time.sleep(3)
ScatterTextWidget.text_colour = [0, 0, 1, 1]
print "function ran"
t = threading.Thread(target= zaaa)
t.start()
class ScatterTextWidget(BoxLayout):
text_colour = ListProperty([1, 0, 0, 1])
def change_label_colour(self, *args):
colour = [random.random() for i in xrange(3)] + [1]
self.text_colour = colour
def press(self, *args):
self.text_colour = [1, 1, 1, 1]
class TataApp(App):
def build(self):
return ScatterTextWidget()
if __name__ == "__main__":
TataApp().run()
