Qt Crash Course for Beginners - Create C++ GUI Apps

[@Cpp_Ninja]

PLEASE do more of the Qt videos. Just got into C++ last week and this is awesome. So glad I stumbled into your channel, thanks bromeo

[@rishi8413]

broooo, u r fucked up

[@spicygaming9528]

Bro you are the best finally someone who elaborates on the stuff that he teachers. Keep it up

[@wearesciber]

Thank you

[@ГерманАксаков]

Really useful for beginners. I am glad that there are not some trunk in the first video of learning qt. Thank you very much, Sciber. I hope you keep it up

[@wearesciber]

I'm glad it helped. Thank you for the comment

[@franckmekoulou4314]

Bonjour, depuis le temps que j'attend une serie de tutoriel dessus, c'est tres excitant. Merci

[@wearesciber]

Glad to hear, hopefully we'll continue this as a complete series. 😸 💚

[@wladfan]

Thanks for the tutorial! This is the first one that I actually got working...

[@humorbender754]

Great video! The example is simple, but complex enough to show how the project is structured and how it generally works. For me the video could have been shorter, because most of the information I found interesting was in the first half of it, but that doesn't change the fact that the explanations were top-notch - clear and informative. Also, on a side note, I have found your voice really calming and therefore nice to listen - that's certainly a great trait to have as an instructor! :D Thanks for the video!

[@DavisTibbz]

Thanks. Great for beginners. I just wished you used "double" instead of int. But thanks. Please show how to add ICON to application next time

Very helpful vid for getting started! Also, Everything app is my new fave search method. Thanks!

[@LUTHFIZXC]

Glad I'm found this channel

[@PhantasyAI0]

Perfect short tutorial that gets to the point, thank you bro. Do you have any tutorials on deigns for qt? For example to make the UI look good, add gifs images so on. just styling things, would love a video on that!

[@wearesciber]

Thanks for the kind words. I am working on a styling video, just thinking about what to include and what not.

[@adityaanand6094]

Wow best video on qt tutorial i found till now

I think God should make you his superior Angel, How I wish i could subscribe like 3 Trillion times for you. You make things so so so easy. From now on I am your number 1 fan. I just don't know what to say. I will end here and say a big thank you for your hard work and smart tutorials. Please make more if you can.

[@wearesciber]

Haha this made my day ♥️

[@yakubcemil850]

[@wearesciber]

Will do 😊

[@KamranBhutto]

@@wearesciber yes I like your videos

[@enricosaccheggiani3192]

Wonderful job . Thanks a lot

[@gawrbage]

Great tutorial! My only problem is that you compiled a debug version of the application and not the release version of the application. This is probably the reason why it is asking for the libgcc DLL files in order to run.

[@wearesciber]

Thank you. I'm not sure if that's the case. I am using Qt6 now and it seems there is no error once i run windeployqt6.exe on either the debug or release version of the app. If i run windeployqt.exe on it, i get the error. Perhaps, it was their fault all along. Anyways thanks for mentioning this. I really should have exported it in release mode nevertheless.

[@bennguyen1313]

I have an existing c++ console-application (VS Studio Community) that uses std:thread, to interface to the serial port (1st thread), can-bus (2nd thread), and a (3rd) logger thread that receives data from the other threads and writes to a file. Now I'd like to make the application into a GUI.. Would adding another std:thread for the Qt-Gui be easier, or should the app be written from scratch using Qt's multitasking (i.e. re-write the serial port and can-bus code to use QThread not std:thread)? Is linking to other libraries easy under Qt Creator or would using Qt in Visual Studio be easier?

[@JohnSmith-lc1ml]

How come you didnt have to connect the buttons using connect(ui.btnAdd, &QPushButton::clicked, this, &MainWindow::on_BtnAdd_clicked). I was following along and none of the buttons were working until i added that line

[@shubhamnijhawan9871]

Amazing video.

If you add the qt mingw bin to %PATH%, the build .exe can run. No need to copy missing dll.

[@pradeepkumarreddykondreddy7048]

Qt widgets application vs Qt quick application. When to use which one ?

[@wearesciber]

Qt offers two main approaches for developing graphical user interfaces (GUIs): Qt Widgets and Qt Quick. Qt Widgets is a traditional, object-oriented approach to building GUIs using widgets, such as buttons, labels, and text boxes. It uses the QPainter system to draw graphics and provides a native look and feel across multiple platforms. This approach is best suited for building desktop applications with complex user interfaces that require fine control over the layout and behavior of individual widgets. Qt Quick, on the other hand, is a declarative language for building fluid and dynamic GUIs with animations and transitions. It uses QML (Qt Modeling Language) and JavaScript to define user interfaces, and leverages hardware acceleration for graphics rendering. This approach is best suited for building modern, mobile and touch-enabled applications, with fluid animations and UI elements that respond to user interactions. When deciding between Qt Widgets and Qt Quick, the choice depends on the type of application being developed and the specific requirements of the project. If the application requires complex user interfaces with a lot of widgets and fine control over the layout and behavior of the individual widgets, then Qt Widgets is the best choice. If the application is focused on a modern, dynamic and fluid UI with animations, then Qt Quick is the better choice. It is worth noting that Qt Widgets and Qt Quick are not mutually exclusive, and they can be used together in the same application. For example, an application may use Qt Widgets for its main window and menus, while using Qt Quick for its dynamic, interactive and visually rich content.

First time to hear about Qt I'm flutter dev

[@sukivirus]

I never understood the license structure for open source QT programming so I stopped using QT longtime ago. The library is commercially only viable for big companies. :(

[@peetcoetzee]

If you split the UI and the business logic you can provide the UI as free open-source to the customer. Your business logic can reside in another (C++ or other) app and the two apps can communicate via IPC or something similar.

[@eocapone]

This video helped me a lot, but, when I do the windeploy procedure, and, I added 4 .dll that were missing, the app still don't run and shows the message "The procedure entry point _Z9qt_asserPKcSO_i could not be located at the dynamic link library". Could you please tell me how to fix that problem?

[@rossmaxx]

I found windeployqt to be buggy.

[@yukunfang312]

Did you run the 'windeployqt.exe' which is mentioned in the video? There are a lot of files to generate.

[@PainterWoW]

You should not send customers the debug version of your program. Compile a release

[@wearesciber]

Right. I forgot. Guess i could say i left that as an exercise for the viewer to figure out 😉😆

[@Rahman_dh]

I have a problem when creating a new project, it keeps reading it and doesn't show the sources and forms on the projects list. Also main.cpp shows a warning says "this file is not part of project. The code model might have issues parsing this file properly."

[@foeyloozer6299]

I know this may not be the most appealing solution, but I had the same problem as you. I ended up just creating a Linux virtual machine and installing qt creator on there. Works perfectly.

[@Sandhyajamakhandi]

Can you share the links to crash course for MFC application of vs

[@bethwelkaranja]

The installer you are using does not match the one in the download link you provided. The one on the download link has some "at least one valid and enabled repository is required for this action to succeed"

i downloaded the missing dll and i still have an issue that pops and i need help solving it as soon as possible please this error in execution file The procedure entry point _Z11gt_assert_XPKcSO_SO_i could not be located in the dynamic link library can you help me

[@wearesciber]

Did you ask chatGPT (or bard). This is one of the most useful utilities that people ignore these days. To be honest, that error message doesn't look familiar to me at all. I would google it or ask chatGPT or bard. So I feel like if you did it yourself, you might just be able to debug the issue far more effectively and easily.

Can you make 1 video about the search function in the file. C++ GUI

Can you import a desgin from qt design studio intto qt creator?

[@DungVu-di7dz]

with Qt, I have difficulty adding libraries from outside

[@rickfuzzy]

You’re kidding. Are you saying you need to manually copy files and join telegram groups just to be able to export an application. Surely not…

[@wearesciber]

I'm sorry, the issue is with Qt itself. It DOES NOT export the app properly. You can find the files needed in the qt directory itself. No need to join the group and download from somewhere you don't trust. You can just look at the file names from my video and find them under the Qt installation directories. I don't know why it doesn't export properly.

[@rickfuzzy]

@@wearesciber Ok, so i did this experiment on my own and none of these steps were required. i simply executed "windeployqt myapp.exe" in my build folder and everything deployed and launched perfectly. All files were incluided.

[@chessmemes-]

please someone help me at 3:00 only the first 2 options are shown (there is no desktop development option) can someone tell me why

[@wearesciber]

Do you have telegram? Because someone had the same problem and we solved it. I have the instructions in the telegram group. If you could join the group and see the messages, it would be much easier. Anyways, after you select custom installation, click on LTS from the right side and then click filter. Then from the left side you can select Qt and from there you can select the latest Qt version. You can go through the check boxes and uncheck things like android to reduce the installation time.

[@PaulNOWAK-wc2ui]

Hello ! I'm interested by your tutorial, but I don't find the "Qt 6.4 for desktop development" 'or the updated version) at 3:07 when I try to follow it. Should I install it previously or I don't require it for the tutorial (should I pick custom installation or Qt design studios instead ?) ? Thanks for answering fast, please

[@wearesciber]

Sorry it seems qt changed the ui a bit. Do custom installation Then from there you can select the qt version If you are facing more problems send screenshots to sciber.dev/tg :)

[@PaulNOWAK-wc2ui]

@@wearesciber heya, thanks for the answer after I select custom installation, I have a list of components I need to install. Should I only instal Qt 6.5.2 extension ? Or I also need another one ? It's because the installation needs from several hours to 2 days to complete. Sorry, I can't send you screenshots, I have trouble using your link.

qt and gtk are nice, but imgui is banger than them.

[@wearesciber]

Sure, imgui also offers more control over whats happening thanks to immediate mode, but also, Qt makes it really easy to design and develop applications with Qt Design Studio. So, need to choose what's best for our specific application.

@@wearesciber tbh at this point idc if it's qt, gtk, winforms or imgui, i just don't want a app in electron. like even after having such nice frameworks they use electron just because their webdev team can handle it ig.
