The Lounge

@inam said in decline of Qtforums: Qt forums are quieter because AI gives fast answers, licensing feels restrictive, and younger developers favor Flutter, React Native, or web apps. Qt remains strong in niche industries, and initiatives like Qt Academy can help, but casual forum activity will likely stay low. About a month ago you wrote the exact same thing with just a handful of words changed. If you don't have anything new to contribute, you should stay quiet. And if you are really a bot, I'd like you banned on the forum.

The “Cannot download archive” error happens when a mirror is down or blocked. Use a working mirror by running the Qt online installer from the command line with the --mirror <URL> option. A reliable mirror example is http://www.nic.funet.fi/pub/mirrors/download.qt-project.org. Check the mirror list here: https://download.qt.io/online/qtsdkrepository/windows_x86/desktop/qt5_5152_src_doc_examples/qt.qt5.5152.doc/5.15.2-0-202011130724qtquickcontrols-documentation.7z.mirrorlist

Maybe with a custom QGraphicsEffect calling drawSource with a scaled/translated QPainter. Another solution would be to use QWidget::grab() periodically to get a QPixmap of the widget and overlaying that on top of it. For potential future readers looking for the minimap keyword: In Qt Quick it's pretty easy to do so with just a scaled down ShaderEffectSource.

For an address verification error during a Qt product purchase, you’ll need to contact Qt support directly. The community forum won’t be able to resolve checkout issues.

CMake can be frustrating, especially when dealing with Windows SDK dependencies across different machines. Its main purpose is to standardize builds and manage cross-platform projects, which helps Qt stay portable in the long run. If portability is key, consider using Qt’s online installer or prebuilt packages to avoid some of the CMake headaches.

@cbum63 Using AI for a Qt GUI can jumpstart your design and save time if you’re new, but it often creates messy layouts and oversized windows. For experienced users, manual design is usually faster and helps you stay sharp. AI is best as a helper, not a replacement.

It's hilarious, when you go to Akismet.com their front page is flaunting that their spam filter is accurate 99.99% of the time. Wow, we must all be the 0.01%

With everything I've read, I'll try to respond to your questions more explicitly. @Cfan said in Questions about CRA regulation(Cyber Resillience Act): If I create an LGPL licensed app and sell it in EU(online sell), does CRA regulation apply to my situation too? The only excemption from the CRA is non-commercial open source software. So, if you want to sell in the EU, your software will fall under the CRA. I am not sure what you mean with an "app under the LPGL". Is all your own code open source as well? Then you "only" need to follow articles 13 and 14. If your own source code is not open somebody has to follow more rules. If you are located inside the EU it'll be you yourself. If you are located outside the EU it will get more complicated. I am not sure what roles are distributed to "manufacturer", "importer", and "distributor". It might be that the app store might have to fulfill some of the duties instead of you yourself. @Cfan said in Questions about CRA regulation(Cyber Resillience Act): If my app does not use networking or internet, does it change something? Yes. There is the category of "important products with digital elements". What makes a product "important" are things like internet connectivity. "Important products" have to fulfill additional obligations. Without any additional knowledge about your actual app I would guess that it is not an "important product". You'll find a list of important products in Annex III.

A TODO.md file in the project directory, with a VS Code markdown plugin.

What update rate is being attempted? What does the general program structure look like?

Thank you for your reply. Your suggestion was the key to solving a problem I had been struggling with for a very long time. You were completely correct. The root cause was a Qt 5 vs. Qt 6 API change. I was trying to use the obsolete QCameraInfo class in my Qt 6 project. As soon as I refactored my code to use QMediaDevices::videoInputs() and the QCameraDevice class, the "file not found" error was resolved. I had spent many hours trying to fix what I thought was a broken installation, so your insight was incredibly helpful. Thank you for sharing your knowledge!

There are a great many who would use it (like my father). However, VB6 has been deprecated by MS since the 1990s, so I cannot envision The Qt Company implementing this.

Just to be sure because some beginners mix QtCreator and Qt: The version of QtCreator usually doesn't matter. You can still use older versions of Qt with a newer QtCreator. There is usually not much reason to use an older version of QtCreator. What you most likely mean is old versions of Qt. The installer uses a filter to show the most relevant versions. In my version of the installer (not sure if it is the most recent one) to the right of the search bar is a drop down saying "Show". In that list you can enable "Archive" to show older unmaintained versions of Qt. However, this history does not go back right to the beginning, but only selected versions of Qt are shown.
