[Development] Qt 5.12 new features

Hi Vlad,

While deprecated, Qt Quick Controls 1 is still part of Qt 5.12, so you can continue using it. It’s performance is not adequate for many use cases, and Qt Quick Controls 2 fixed that.

Qt Quick Controls 2 is the one we are actively developing and it adds many nice features in Qt 5.12. TreeView would certainly be a natural addition to Controls 2.

Yours,

                Tuukka

A bit unclear about deprecating QQC1
Since in QQC2 no TreeView and even no plans for this, isn't it a bit too early to deprecate QQC1?

thanks

5.11 included WebGL TP2. Is there any change? Why is it staying TP2, or should it be TP3?

5.12 looks like it'll be a pretty great update!

I'm not sure what's on the agenda for 5.13... but as I mentioned on interest, one pain point I continually have is the amount of custom platform integrations for mobile. This is one area where Xamrain excels, as they have a simple property on an object you can set to control things like the status bar visibility, the screen brightness, etc. The downside is the Xamarin stuff is all platform-specific so using a iOS property on Android won't work. This is one area where Qt can leapfrog the other platforms including React Native by being cross platform. Anything that doesn't require me to write Obj-C is a very good thing!  I figure this would need to be a few Qt Quick/QObject Singletons. Notifications should be supported too, and this could also be used for desktop platform notifications as well. The notifications support would only need to cover being messaged my the platform, and not any display - this would get me out of having to deal with Obj-C almost completely. (My beef wi
 th ObjC is other than being not good at it, is whatever I'm writing isn't cross-platform. Java I am more comfortable with, so I complain less, but I still cringe on the non-portability!)

Looking forward to 5.12!
