How to add a screen

Step 1: Create a new file, add the following Template for a clean Screen

'''Module XYZ:
This is the documentation for the Module that explains the
main usecase of this Module and details it's usage.
'''

from kivy.uix.screenmanager import Screen
from kivy.lang import Builder

class ScreenSponsor(Screen):
    '''This is the documentation for the Screen that explains
    the main usecase of this Screen and details it's usage.
    '''

    # Here we define the UI of this screen.
    Builder.load_string('''

name: 'ScreenSponsor' # your Widgets here, we just use 2 buttons in boxlayout as demo BoxLayout Button Button ''')

Take special note of the names::

The `name: ScreenSponsor`, in this same as the class name `class ScreenSponsor(...)`.

Step 2: Save the file as screensponsor.py in the folder <PyDelhiConf/pydelhiconf/uix/screens>. Take note to name the file same as the class name, in our case ScreenSponsor in lowercase with .py appended at end.

That's it. Now to load this screen::

Button:
	on_release:
        app.load_screen('ScreenSponsor', manager=app.navigation_manager)

manager= is a optional parameter, which specifies which ScreenManager to load this screen in. If it is omitted this screen will be loaded into the main Screen Manager Which is responsobile for loading StartupScreen and NavigationScreen.
