Backface Culling Toggle Button for Blender GUI project

Question

I have been working on my project for Blender for quite some time and have reached the end of this small section, but I want to add a toggle button to the GUI that toggles if backface culling is off or not, I have tried using the command:

bpy.context.space_data.shading.show_backface_culling = True

and the opposite but when I run it in the python script, it says:

"SpaceTextEditor" object has no attribute shading

I know it's probably something really simple.

Answer 1

When you run bpy.context.space_data in the TextEditor, the context will be within Text Editor by default, and thus space_data will be of type SpaceTextEditor. When you run that code line in the Python Console, the context will be within the Python Console by default, and thus space_data will be of type SpaceConsole. But the attribute shading is part of the SpaceView3D class so you have to override the context to be within the 3D Viewport which you can do by using the following script:

import bpy

area_type = 'VIEW_3D'
areas  = [area for area in bpy.context.window.screen.areas if area.type == area_type]

if len(areas) <= 0:
    raise Exception(f"Make sure an Area of type {area_type} is open or visible in your screen!")

with bpy.context.temp_override(area=areas[0]):
    bpy.context.space_data.shading.show_backface_culling = False
