How to change the background of main panel?

[carlosporta]

I can't change the background of the main panel using canvas. How can I do that?

So before I was using this NavigationDrawer in my app, I was setting the background color of my app using:

from kivy.core.window import Window

# red background color
Window.clearcolor = (1, 0, 0, 1)

But since I added NavigationDrawer, my whole app's background color is back to the default black. I'm guessing that this is some bug that overrides the Window in some way?

This does appear to be a bug caused by "black" being hard-coded in three places.

The fix, I guess, would be for NavigationDrawer to go up the widget stack and determine what the background is (maybe with Window or Rectangle?) rather than hard-code "black"

It appears that the background of the sidebar in the nav drawer is set to black on this line, so change this line to change the background color of the drawer itself:

• garden.navigationdrawer/__init__.py

  Line 173 in 8e1935e

  rgba: (0,0,0,1)

It appears that the background of the rest of the app is set to black on this line, so change this line to change the background color of the main panel:

• garden.navigationdrawer/__init__.py

  Line 193 in 8e1935e

  rgba: (0,0,0,1)

There's also this other line that hard-codes "black," but it's not immediately obvious to me what it's for:

• garden.navigationdrawer/__init__.py

  Line 199 in 8e1935e

  rgba: (0,0,0,root._anim_progress*root.main_panel_darkness)
