Не получается сделать так что бы текст в kivy появлялся по символу ,а не весь сразу
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from kivy.clock import Clock
class MyBox(BoxLayout):
def __init__(self, my_text, **kwargs):
super().__init__(orientation="vertical", padding=10, spacing=10, **kwargs)
self.letters = []
for i in my_text:
self.letters.append(i)
self.label = Label()
self.add_widget(self.label)
self.a=0
self.label.text= ""
while self.a < len(self.letters):
try:
Clock.schedule_once(self.change_text, 0.1)
self.a=self.a+1
except:
break
def change_text(self,dt):
try:
self.label.text = self.label.text + self.letters[self.a]
except:
print(self.a)
class MyApp(App):
def build(self):
box = MyBox("пример текста")
return box
app = MyApp()
app.run()
