    @Giridhar Two comments- QT examples are as received from some comments on forum " very basic ". That is OK , but lack of function description , lack of description of passed parameters to the function, and overall lack of "comments" eliminates "examples" as a learning resource. ( as a poorest example - error processing in non existent in examples - I have been told "it is not basic " to process errors ) Same goes for using forum as a learning resource. The forum unadvertised purpose is to resolve coding issues. There are some very knowledgeable contributors doing so, but they are a minority. So far I have not found many technical forums as a beneficial learning resource - most "how do I ..." receive reply "Google it ". As far as "doing a survey " - that is your choice to "get up the speed " in your job , I would suggest to skim the forum, it may also help. Good luck Cheers

    @JoeCFD said in Vibe coding / AI code generation for Qt based applications: As of late April 2026, SpaceX has secured a deal with the option to acquire AI coding startup Cursor (Anysphere) at a $60 billion valuation later in 2026. Qt has QtCreator and can easily add any AI engine. What a loss of opportunity! What opportunity are you talking about ?

    You don't have deprecation warnings on, or you would not suggest foreach :P Don't use it, I'm surprised its still in the library I would suggest simply writing the c++ way with std::as_const Or if you insist on "simpler" macros: #include <utility> // std::as_const #define FOREACH_CONST(var, container) \ for (const auto& var : std::as_const(container))

    Whether the implementation is "lock-" or "wait-free" depends on the processor and C++ standard library implementation. https://doc.qt.io/qt-6/qatomicpointer.html#feature-tests-for-the-atomic-api An operation that completes in constant time is said to be wait-free. Such operations are not implemented using locks or loops of any kind. https://en.cppreference.com/w/cpp/atomic/atomic_is_lock_free.html All atomic types except for std::atomic_flag may be implemented using mutexes or other locking operations, rather than using the lock-free atomic CPU instructions. Atomic types are also allowed to be sometimes lock-free: for example, Use the macros and is*WaitFree() functions documented for QAtomicPointer It's also worth looking at the Qt and C++ memory ordering semantics documentation. *Ordered() is the most conservative approach. Imposing ordering limits the optimizations that a compiler and CPU can apply. The use of atomics also impacts memory cache coherency, potentially causing neighboring non-atomic data to be flushed.

    @SimonSchroeder There is a single project that allows you to do hot reloading with C++ (and thus certainly also with Qt): https://liveplusplus.tech/ Only problem is that it's closed source

    Today there is only a single pretty expensive license. But in the past, I remember there were other cheaper versions. For example the "Indie Mobile Edition". So a edition only for mobile devices (and i guess only Qt5 only, but I am not 100% sure). I guess they have one of that versions and/or they use a module that isn't available with Qt6 yet (don't forget that some modules are not available with Qt6!) But maybe ask them if you want to know more.

    @JonB - this does look like it'll suit our needs, if we decide to re-purpose the Java into a server. It's another approach I can add which I'd not thought of, thanks!

    Hi and welcome to devnet, AFAIK, Qt now provides helper macros to make use of e.g. windeployqt to prepare a folder structure that allows your application to run. You can then use your favorite package manager or CPack to build the installer. For Linux, it begs a different question: are you aiming at providing native packages such as deb and rpm files ?

    @BoudiVV Hi! Not sure what your question or concern is. Why do we need a different way to work together? What would be different? "merge of QT with CSS" - what does this mean? "But we can no longer accept that there is no honest earning model for all the developers involved" - do you mean Android/iOS app developers? Qt developers?
