Re: [kivy-users] Changing Screen on Build

[Elliot Garbus]

Move your code that sets the screen from build to on_start().  The on_start method is called after build has completed.

When my app builds and loads, I want it to use a function to display a certain screen based off if the database is filled. If the database is filled, it will go to the main menu. If not, it will go to the startup screen. 

Before trying this feature out, my app would return the kv builder with all my screens when it executes.

I am not sure the best way to do this or if I should create a function inside the screen manager class? Trying to do that and triggering it with using on_pre_enter and it did not work. 

Example: 

class WindowManager(ScreenManager):

pass

kv = Builder.load_file('kvs/new_window.kv')

class AwesomeApp(App):

def build(self):

if check_for_admin_info() != 0:

kv.current = 'admin_name_window'

else:

kv.current = 'main'

return kv

Thank you in advance!!
