I mean, just run a `find Qt5Core.dll` on windows or `find QtCore` on mac and see what's using Qt on your machine

https://en.wikipedia.org/wiki/Category:Software_that_uses_Qt

This is going to be a very limited list though, for instance there are dozens of applications in my domain that use Qt, and none of them are on this list.

FWIW this is a plus :-P i prefer working with Qt's containers and strings than STL (not specific to Qt really, i prefer almost any other container, string, etc library than STL, the API of which i find very unintuitive). Qt isn't just a library really, it is a framework you build your application around, when you use it you are supposed to buy in everything it does.

- how do you implement reflection without either ugly macros or a precompiler?

- how do you implement metaclasses without a meraobject ? (e.g. how would you list all the methods or properties of a class)

- how do you implement a tree structure where the parents knows its children and the children know its parent in modern C++ (or Rust without unsafe :-)) ?

That statement lies somewhere between simplistic and out-right wrong. Qt uses pointers just like C++'s smart pointers use pointers.

Moreover, Qt also provides a collection of smart pointers, which are used quite extensively by Qt.

> meta-objects, pre-precompiler

I fail to see the point of your complaint. Besides the fact that Qt's "pre-compiler" is used to transparently support stuff such as UI design tooling and Qt's resource system (which handles embedding images and i8n), Qt's meta-object system also adds the boilerplate code that implements stuff such as event loops, IPC, observers, and message-passing.

So, actually, what's your point?

This complaint is particularly absurd if we compare Qt with unquestionably modern technologies such as the Android stack, whose build process is jam-packed with precompiler steps and whose project trees are filled to the brim with XML-based DSLs.

> inheritance over templates, little use of the standard library

These complaints make absolutely no sense at all.

> need I say more?

...Yes? You actually failed to make a single point, let alone presented a rational argument to back your assertion.

> It is leaps and bounds beyond other things - but those leaps and bounds are into the past.

This jab is simply stupid, more so in light of your complains.
