So I’ll throw my 2 cents worth of experience into the ring.
I’ve developed a desktop application using Qt Widgets since 2009 era. Last year
we got funding to completely rewrite it from the ground up. We selected QML
over widgets because we wanted that forced Model-View-Delegate and separation
of the back end from the front end. QML sure looked promising from the demos.
The early prototypes were nice. What we got for development is a hot mess. The
QML debugger is a joke. GammaRay helps here and there trying to figure out what
rectangles are where. The development time is horribly long. QML itself is just
a black-magic soup where you never really know when things are getting
initialized. We were hoping to have a flashy desktop application, all “modern”
and everything. We are months behind schedule at this point. We spend hours
messing with QML trying to get it to behave appropriately (sizing, visual
style) where widgets would have just been “done”. We spent a large chunk of
cash paying someone to get a TreeView working since Qt5 doesn’t supply one
(Don’t get me started on that.. ).
Had I known back then what I know *now* I would never have selected QML over
Widgets for Desktop development. In no way is it ready for anything past some
trivial applications. Not even close. The idea is great. The vision is cool.
Our development experience has not been a good one.
@Mark Gaiser one of our contractors implemented some code up in main.cpp where
we press “F7” and the app reloads using the QML files from disk. This helps us
cycle the theme updates and QML updates instead of having to quit and restart
each time.

Hi,
QML is nice for basic applications but widgets is important for professional,
technical
and high-density applications.
But that doesn't matter. From my point of view Qt stopped being developed as a
desktop
framework a long time ago. Other industries seems to have priority now.
Well, it was nearly good enough in the Qt5 days with Controls V1.
All they needed was a better set of controls to accommodate mobile more and
reduce complexity in V1.
What they did - conceptually - with V2 was good.
But it seems like they just left it in alpha quality and call it "ok" to
replace V1.. That was a mistake.
It needed much more development time to be a proper replacement.
We're now like ~8 years past the introduction of the V2 set...
And it still has really severe bugs that just interrupt usability. 8 years...
So I doubt it will be getting any better at all.
