Create An App
Now It is easy to create simple kivy app
1. Sub-Classing the App Class
2. Implemennting its build() function mathod so it returns a Widget instance the roon of app (the root of your app widget tree)
3. Instantiating this class, and calling its run() method, run method is run the main app
The sample of small app
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput
class Loginscreen(GridLayout):
def __init__(self,**kwargs):
super(Loginscreen,self).__init__(**kwargs)
self.cols = 2
self.add_widget(Label(text="User Name"))
self.username = TextInput(multiline=False)
self.add_widget(self.username)
self.add_widget(Label(text="Password"))
self.password = TextInput(multiline=False,password=True)
self.add_widget(self.password)
class MyApp(App):
def build(self):
return Loginscreen()
if __name__ == "__main__":
MyApp().run()
