Qt Desktop Days Keynote – Qt 6 for the desktop – What can we expect?

My favorite app made with QT ever is Telegram client.

It's so fast to use and the UX is incredible. I'm curious how much custom code is there per platform or QT takes care of most everything.

I'd love to maybe learn QT but C++ always seemed hard to approach although I know there are bindings from various languages to it.
