Yes, I'will give you and example with this folder structure
-Project\
--main.py
--main.kv
--folder1\
----window1.py
----window1.kv
--folder2\
----window2.py
----window3.py
--folder3\
----window4.py
----window4.kv
folder\window1.py will be like
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.lang.builder import Builder
from kivy.uix.widget import Widget
kivy.require("1.11.1")
# Builder is neccesary to work with multiple files
Builder.load_file("folder1/window1.kv")
class login(BoxLayout):
def __init__(self, **kwargs):
super().__init__(**kwargs)
class login_window(App):
def build(self):
return login()
if __name__=="__main__":
aplicacion=login_window()
aplicacion.run()
folder1\window1.kv is not necessary to specify.
main.py will be like
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.lang.builder import Builder
from kivy.uix.widget import Widget
# Import files like
from folder1.window1 import login_window
from folder2.window2 import example2_window
from folder3.window3 import example3_window
class manager(BoxLayout):
# Add screens to main
login_widget=login_window()
example2_widget=example2_window()
example3_widget=example3_window()
def __init__(self, **kwargs):
super().__init__(**kwargs)
# Check kv file to understand these lines
self.ids.screen_login.add_widget(self.login_widget)
self.ids.screen_example2.add_widget(self.example2_widget)
self.ids.screen_example3.add_widget(self.example3_widget)
class main(App):
def build(self):
return manager()
if __name__ == "__main__":
main().run()
main.kv will be like (Which has the ScreenManager!)
#:kivy 1.11.1
<manager>:
id: main_window
ScreenManager:
id: scrn_mngr_main
Screen:
id: screen_login
name:'screen_login'
Screen:
id: screen_example2
name:'screen_example2'
Screen:
id: screen_example3
name:'screen_example3'
Now, to control the program flow yo need to add these lines in window1.py
self.parent.current='screen_login'
self.parent.current='screen_example2'
self.parent.current='screen_example3'
