Hi Nicholas,

Thanks for the response - you are aiming just outside of my level of 'full understanding' how all of this is supposed to work together :-)

Cool - that's a good place for me to start reading and understanding how this all fits together. So far it's been all "git grep" and trying to find something that I understand and that does what I want :-)

That definitely sounds like the right way to go.

I don't think we do (I know, terrible answer, showing that I'm not fully understanding the toolkit that I use for my app.
The main target platforms for the app are Android and iOS - but you can run 'mobile on desktop' both on Linux and Mac.
My guess is that QQC2 has a different style for each of these platforms.

I'll do some reading based on all the new information that you provided and see what I can figure out.

And of course -- always grateful for more pointers :-)

Thanks and happy holidays!
