kivy: change background color to white

Tags:

kivy

I'd like to have an app with black buttons and labels, and with white text, and thus, would like to have white space separating these widgets. I suppose that in order to do so, it would be necessary to convert the background from the default color, which is black, to white. What is the best way of accomplishing this? Thank you!

How do I change the background color to white in Python?

In Python/OpenCV, convert to HSV. Get the HSV values at the top left corner. Do inRange() thresholding on the HSV image to make a mask. Use the mask to change the original image color to white where the mask is white.

A simple way is to simply draw a big white rectangle behind your root widget. For instance, in kivy language you could do

<YourRootWidget>:     canvas.before:         Color:             rgba: 1, 1, 1, 1         Rectangle:             pos: self.pos             size: self.size 

I think you can also actually directly set the colour that kivy clears the window background with, which is exposed as Window.clearcolor. You would do this with

from kivy.core.window import Window Window.clearcolor = (1, 1, 1, 1) 

You would probably need to put this before anything else in your app, as it won't affect anything if run after the window has been created.
