Why isn't qt so popular



  • Why isn't qt popular for other types of applications like web, mobile except desktop and embedded? i saw that qt qml is also effective as other web technologies for web development, so what makes it less popular in web and mobiel fields? What does it lack?


  • Moderators

    You should rather ask people who are not using Qt :-)

    I think there are many reasons:

    • native mobile languages are - naturally - more supported and endorsed by each platform
    • using Qt for mobiles is an extra step. Not only you need to install all SDKs, NDKs etc. but also install Qt, and make it work which is sometimes tricky. With Xcode/Android Studio alone it's simply easier to start
    • C++ is considered to be a hard language
    • many people already know Java/Swift/JS but do not know C++, Qt or QML
    • Qt Commercial offering is unclear, weird, expensive and complicated
    • neither of the big players (Apple and Google) have embraced or encouraged the use of Qt
    • just history... I'm pretty sure if back in the day Nokia did not completely miss the changing market, Qt would be much, much stronger on mobiles now
    • web - well you can't quite use Qt on web. It's only very recently that WebGL streaming and WASM became possible with Qt, other technologies were quicker. And again - web devs don't know C++ and have no reason to learn it

    What does it lack?

    Oh, too much to list ;-)

    Don't get me wrong, though - Qt on mobiles (and on web) is possible, usable, and there are many products on the market using it.



  • The reason Qt isn't more popular in general is simply a steep learning curve. Historically, software engineers aren't known for their patience -- probably because their users aren't either -- and rarely have time to invest in learning an entire platform. It's unfortunate, because Qt is a superb platform, and is wonderfully documented (for the most part).

    Another reason, specific to mobile devices, is that Qt's claim to fame: "write once, build anywhere" just isn't that important to mobile developers. Few apps scale well from phone to tablet to desktop, so the benefit isn't there. In fact, as apps continue to flourish for mobile platforms, it seems that they're stagnating for the desktop, as browser-based solutions continue to encroach on their space.

    I can't speak to Qt's web technology, but I'd hazard a guess that it's hard-pressed for a general-purpose platform to compete with ad-hoc development solutions for web applications.

    None of this is to say that Qt's future is murky; in fact, it's quite bright. I think it will continue to attract developers, but not so much for its "build anywhere" feature as its feature-richness, solid integration with other technologies, and...the best user forum on the planet.



  • As a GUI in C++ I think Qt is popular of course by excluding non-C++.

    Problems I see with Qt is:

    • not the whole Qt Library is LGPL. Qt Charts for example is afaik GPL. I personally do not use Libraries under GPL. Only LGPL or permissive. So I only use LGPL Qt parts.
    • C++ has a bad reputation as hard language.

    Probably startup companies are afraid of getting copyright lawsuits if they use Qt at beginning. (just guessing not sure). If I start a company I would not have so much money to pay a commercial license.

    $499 per year shouldn't be too much for a startup: https://www.qt.io/en-us/qt-for-small-business



  • @jsulm
    if you start from Scratch? I mean Just PC and money for food and Rent. and maybe some state money. If I lost job and started a company I probably would not be able to pay 500 Bugs. Not because I would not have 500 USD I needed some savings, since state unemployed insurance is not that high. It depends of course how fast my company grow in the next months. But I am rather careful about future forecasts.

    It is even if it requires moc as additional build step.

    Lol, the passion of people. Next thing they will say is HTML is not a machine learning language...



  • @jsulm No sir, It may not be big amount for you or in your country. But in other countires
    it is more than 50k which is soo expensive for begineers to start with. You may think salary may be high but it's 1/3 times less than that monthly.Although I don't work. I am sure it is one of the bigger reason that people don't use it. Instead other frameworks are free of cost. I consider as biggest reason of its low popularity.
    If QT will be free, I am sure the no. of developers will increase hugely



  • @Thank-You
    As discussed, the small business commercial offering does not cost "50k". $500 is not $50k.

    In any case, the community edition is free, so why not use that? Why do you need the commercial edition?



  • @JonB said in Why isn't qt so popular:
    Nope bro, In other countries it is equivalent to 50K of that country 😂😂 Not dollars
    Can we use community edition for small companies to earn some money??



  • @Thank-You said in Why isn't qt so popular:

    Nope bro, In other countries it is equivalent to 50K of that country 😂😂 Not dollars

    Then say so in your response! I had no idea that your "50k" meant in some unnamed currency, and without knowing the currency it could be the equivalent of $1 for all we know! :) [I remember when there used to be 1,500 Italian Lira to the £, so 50k Lira was like 40$ !]

    Can we use community edition for small companies to earn some money??

    Yes, of course, 100%. You simply have to abide by the LGPL for the majority of Qt, or the GPL of a couple of optional packages if you use them. But you certainly can earn money from the community edition, without paying a fee or royalties. The commercial version is essentially there if you want to hide your source code, that's all.



  • @JonB in the interest of full accuracy, there are features not available in Community, right? As well as certain versions (I notice my maintenance tool doesn't make 5.14.2 available to me)?



  • @mzimmers
    Yes. I did italicize essentially. I think the poster I was replying to is going to be a "small" user, hence the summary. Other features, and the release support situation, are more likely (italicized again) to be of most interest to "larger" users.



  • Why Qt is so unpopular? OK lets dicklate:

    • stupid, unclear $500/yr for licence; its counter-productive; when you own startup, and you see $500 tag, you simply go eksewhere; there are tons of raples that are cheaper/free with much greater functions set,
    • shit software like kde, gnome, fuckUI, moodle etc
    • known installer bugs like having to install SHITAS ( fuck you kde )

    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    @macfanpl said in Why isn't qt so popular:

    3 out of 4 items on your list don't use Qt at all....

    • known installer bugs like having to install SHITAS ( fuck you kde )

    There is no KDE stuff in Qt installer ;-)



  • @sierdzio But the first one is soooooo true



  • @macfanpl said in Why isn't qt so popular:

    What toolkits other than Qt do you recommend for C++ development with single source for Windows/Linux/MacOS (desktop)?



  • C++ was dead in the enterprise years ago. Most people writing new C++ projects these days are writing an OS/browser/game engine/stock trading system, which means it's a very niche language. (think what % these projects are, compared to all new software projects). Universities stopped using C++ in their classes at least a decade ago.

    On top of that, the sort of 50yo+ people who still champion C++ in 2020 for general development, hate the readable, well-designed, object-oriented API of Qt, because it's not "pure" C++. They hate that moc adds features to the C++ language that make it more convenient to use, they hate that Qt made their own types even though they're far superior to stdlib's (eg QString vs std::string).

    So Qt is a niche framework for a niche programming language.

    Edit 1: and for your average mobile developer, the expensive license to be able to publish to iOS makes it a non-starter. Everyone else is fighting to give them free dev tools, but here comes Qt saying "pay us $500/month "or whatever it's at now.







  • @JonB so Python is gaining in usage -- big deal; that just means there are more slow apps written these days...



  • Python to me is the new better java. It will last a while but VM-based languages never become "permanent"

    10 years of commercial experience and I have never written any of the programs you mention. Nor do I know anybody who did.

    Which proves nothing, of course, because we're just 2 blokes in an ocean of developers. I don't know what more proper statistics would show.

    Universities stopped using C++ in their classes at least a decade ago.

    Not everywhere. It's still surprisingly often taught around here, which is quite stupid.

    This Qt-hate is sadly true.

    And this is true as well :-|



  • @sierdzio
    Yes The price is huge point for personal developer.
    Can moderators and QT champion raise some voice in it?



  • @Thank-You said in Why isn't qt so popular:

    No.

    And earlier it was said "pay us $500/month", but it's more like $500 per year I believe for the starting license? I'm not saying that's free, but it's 1/12th of what was stated.

    I don't know what facilities of the non-free-community edition of Qt a very small business needs.



  • @JonB
    Just to know,
    Why they can't ?

    Are there any sign about making it free?

    HOPE IT BECOMES FREE



  • @Thank-You
    I still don't know, you haven't answered: in your personal case, what is that you need or want the commercial version for as opposed to the free, community one?


  • Moderators

    @Thank-You said in Why isn't qt so popular:

    Yup. Even for big companies, the pricing of commercial Qt is a show stopper.

    Can moderators and QT champion raise some voice in it?

    I have raised my voice, many times and across multiple channels. No luck ;-) I guess for the Qt Company shareholders are much more important than the community.


  • Moderators

    @Thank-You said in Why isn't qt so popular:

    It is ;-) LGPL & GPL licenses are still available.



  • @sierdzio said in Why isn't qt so popular:

    Yup. Even for big companies, the pricing of commercial Qt is a show stopper.

    I flat-out cannot believe this to be true. The cost of Qt licensing is dwarfed by most Fortune 500 maintenance costs for the Redmond gestalt.

    Come on, guys...the real reason Qt isn't more popular is...it doesn't come from Microsoft.

    Really? What about C++20? 2020 was last year, not "long ago". Before C++20 we got C++17, C++14 and C++11, I don't see how "development of C++ stopped long ago"...

    Thats just wrong, c++20 is a thing, you know, this not just an update for the std-library but includes core features thats compiler vendors have to implement
    like concepts, three-way comparison etc.

    and 23++ already has ton of stuff that is in the making, above all reflection (hope never dies :D)
