Python - Kivy, Have I Structured this wrong? -

at moment have 1 floatlayout in sheditormain, inside class sheditormain i've declared bunch of widgets (buttons, popups, labels, etc..) , used self.add_widget add them.

now want create new window opens inside/over floatlayout , can't seem works. examples i've seen far regarding multiple windows either using app main class creation of widgets inside layouts. suggestions or have restructure code?

class sheditormain(floatlayout):     def __init__(self, **kwargs):         super(sheditormain, self).__init__(**kwargs)as         self.add_widget(blabla)         self.add_widget(blabla)         self.add_widget(blabla)         self.add_widget(blabla)         self.dbconnection = dbconnection()          #declare popups etc       def functionevents(self, instance):         yaddayadda      def functionevents(self, instance):         yaddayadda      def functionevents(self, instance):         yaddayadda   class sheditor(app):     def build(self):         self.root = sheditormain()         return self.root 

please read this answer multiple "windows" , why may not desired. can recommend have kivy window maximized , using modalview pseudo-form can dragged , has button close it. more control on everything, cleaner code, beginner friendly. create custom widget inherits modalview , you.

you can place modals wherever want them - popup source code in repo how positions set. you'll end custom popup can control without crippling original widget.

another way may use screenmanager(or pagelayout, carousel, xyz other widgets) provide mobile-/presentation-like view. sooner kv language, sooner you'll have less troubles imagine stuff out of pocket e.g. see fancy app, can open kivy-designer or more control/less fancy go kivycatalog , type see that's how straightforward kvlang is.

example modals:(old attempt create windows-like... via kivy = floatlayout scatter(only drag enabled) "windows")

which leads me conclusion if think need multiple windows or another window nice whatever reason not sure if it'd work or - don't , overcomplicating things, steal attention important parts of code ui.

(ps, i'd edit answer mentioned @ top, in question user has little bit more complicated problem)
