How to: Do something busy in the background and show a LoadingIndicator

[davep]

With this Discord thread in mind, and as something that's come up more than once over the past few months, and given we've got some really nice tools in place now to easily tackle the problem: a How To that explains how to do something busy in the background and show a loading indicator while it does it would be a good idea.

Even easier now with the new Widget.loading reactive, so perhaps this task can be closed (also #2954)?

Yeah, good call.

I do still think it's a reasonable thing for us to have in the howto; the howto documents aren't really intended to explain how to do something Textual doesn't easily support, they're more like longer-form FishAQs that give a good basic grounding in how to take the tools Textual provides (in this case a loading indicator and a worker to do busy things) and make a very workable thing with them.

I sense it would still be a good thing to howto.

Sorry Dave, what do you think a 'how to' could add that isn't already explained in the docs?
