How to set a screen background image in Kivy

Question

I know how to make a color background but i can\'t seem to find anything useful for setting the image as a background and would be really grateful for any help with my code.

Answer 1

canvas.before:
        Rectangle:
            pos: self.pos
            size: self.size
        Image:
            source: "lights.png"

Image is a widget, you can't place it on the canvas.

What you *can do is either just set a source for the Rectangle:

canvas.before:
        Rectangle:
            pos: self.pos
            size: self.size
            source: 'lights.png'

...or place your Image behind the other widgets by putting them in a container layout.
