Kivy: Multiple items in a popup wont work

Question

I am trying to use multiple items in a popup with kivy in python. I would like to find out how to make this work. I am not sure if it has to do with the fact that the script is on my phone and not made for computer. Here is a little example script that I am asking you to help make work for future reference.

import kivy
from kivy.lang import Builder
from kivy.uix.popup import Popup
from kivy.uix.textinput import TextInput
from kivy.uix.label import Label

popup = Popup(title='Test popup',
    content=Label(text='Hello world'),
            TextInput(text='Hi'),        #Here is what I am trying to make work
    size_hint=(None, None), size=(400, 400))

So you can see it is two objects in one content of the popup. I am sure this is possible because I've seen it on kivy apps in the appstore, but not sure how to do it myself.

Answer 1

The content of a Popup can only be a single widget. You cannot add two widgets like you're trying to do.

To accomplish what you're trying to do you'll have to add the label and text input to e.g. a boxlayout and then add the boxlayout to content. Here's an example that should work:

from kivy.uix.popup import Popup
from kivy.uix.textinput import TextInput
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label

box = BoxLayout()
box.add_widget(Label(text='Hello world'))
box.add_widget(TextInput(text='Hi'))

popup = Popup(title='Test popup', content=box, size_hint=(None, None), size=(400, 400))
