Strategies for debugging layouts?
Yannick Gingras
I was trying to nest an AnchorLayout inside a FloatLayout yesterday and
didn't get it to do what I want, which was to put a label at the top-
center of the float.
Since the layouts are invisible, debugging this felt like a shot in the
dark. In the debugger, I can traverse the widget tree until I get to
the layout and then inspect the position and size, but that seems like
a lot of work and I'm sure some of you have figured a strategy that is
more efficient to debug layout formatting.
The easiest would probably be to draw an outline around all my layouts,
maybe selecting a distinct colour for each of them. Is there an easy
way to do something like that?
How is everyone generally troubleshooting their layout arrangements?
Thanks!

There is a very nice tool in kivy called the inspector.
You invoke it on the command line:
- python main.py -m inspector
then press ctrl-e to bring up the tool. When you click on widgets they are highlighted you can navigate to parent or child widgets.
More details: https://kivy.org/doc/stable/api-kivy.modules.inspector.html?highlight=inspector#module-kivy.modules.inspector

Woah, this is great!
It turns out my label actually was exactly where I wanted it to be, but
the text alignment inside the label was off, which is why the text was
not where I expected it. It took me less than one minute to find that
out with the inspector. Awesome!
