You know when you write code and you know it's a big bowl of spaghetti... :/

@AlexandreVaillancourt Look on the bright side, it's still in a bowl?

There's a decently regarded book out there on dealing with legacy code, which may or may not be your case.

No; it's related to the fact that I want to update a progress bar, and pre-load a not-known-in-advance amount of big-or-small amount of graphics related files. The progress bar is not only for the graphics related files but for "everything".

So I have that 'normal behaviour' of "everything", and I have a 'sub progress' for that particular chunk of the loading.

So the code that handles the progress bar is now a half-ass singleton.

That needs to be used in a particular way.

: it first needs to be initialized with the window handle, because the code that creates the instance has this information, and the value is put in a static variable because the second I need that class that handles the progress bar, I don't have access to the window handle.

But you know what they say: make it work first, then clean it.

@Pikalek the solution is fire right?

@Pikalek I tried shuffling around some of the math / code / commentary in this answer to hopefully help make the thread of explanation a bit clearer.

@DMGregory Again, an improvement on what I did. I was unaware of the \text marker - I really like how you applied it to put captions under some of the math blocks. I may need to back propagate some of this to my other conversions. I hope I'm not generating more work than I'm consuming.

@Pikalek Your edits are major improvements! Thanks for putting in the time. I think in this case it was more that my answer was structured in a bit of an awkward fashion, so it needed more structural change than just a math conversion.

I'd like to find a better way to do wrapping — the way I've done it there feels like a hack and is probably unfriendly to screen readers, if they parse MathJax at all.
