@Kent-Dorfman I will update my code to PyQt6 since I'm doing a rewrite :)

@Christian-Ehrlicher Okay, I finally saw the issue. In my code std::this_thread::sleep_for(std::chrono::milliseconds(100)); was outside the pool.enqueue() function. So the main thread was constantly sleeping and couldn't process the signals.

@oliver_mpt said in Windows compilation problem: The function CreateSyntheticPointerDevice is declared in winuser.h as : I don't know but have a read through https://www.reddit.com/r/gcc/comments/u0q721/how_to_compile_a_shared_library_that_uses_types/ . That was from 3 years ago and said You'll need a very recent version of Mingw-w64. You'll also need to define NTDDI_VERSION to at least NTDDI_WIN10_RS5 Maybe the discussion there will help for this particular issue? Also https://discuss.kde.org/t/kirigami2-for-developement-on-windows-rant/6333/16. If the error comes from Qt sources rather than your own I do not know why it does not run through and compile/link correctly. I do not use Windows for Qt.

Sorry, I found it. I have last version 3.3.1 of "Qt Visual Studio Tools"

Need new class sub-classing QTabWidget MruTabWidget::MruTabWidget(QWidget *parent) : QTabWidget(parent) and installEventFilter

Hi, I think that for this case, you should consider creating a QProxyStyle in order to be able to manage that hierarchy of constraints.

In windows cache is located in the registry

@F32_ To be clear for others: with Qt 6.4.2 under Ubuntu/GNOME/xcb, I am claiming both QWidget & QMainWindow cases are as per the second screenshot above. I never see a minimum height of 3 lines. Which of the two is the "correct" behaviour in the OP's case I do not claim to know :)

@jsulm It turns out you need to use QSG_RHI_BACKEND=opengl instead

... or simply install the debvug symbols with the Qt online installer. What's the point here?

@JonB You're right. I always launch one wsl process in one cmd window, and wsl processes in different cmd windows can live with each other. Now I tried launching multiple wsl processes in one cmd using start /b, the result is the same as this demo application: all wsl processes will exit immediately. So the problem is multiple wsl processes cannot be launched by a single parent. It has nothing to do with QProcess.

Include QStringList header

@thomasGl You can do that with https://doc.qt.io/qtdesignstudio/

Hi and welcome to devnet, For testing frameworks, Qt already provides the QTest module which works pretty nicely. As for the rules, there's mainly one: test both happy and unhappy code paths. That way you ensure that your code is working when everything goes well as well as when issue arise.

Hi, I don't think you missed anything. One possible I can imagine is to create a wrapper function that you would use in your route that would measure the execution time of the real function that you would have passed to said method.

@Pl45m4 honestly, I haven't decided how best to implement it, I thought maybe there was another alternative? I didn't fully understand what you meant, just store in the auxiliary structure not the data but the list of connections?

Seeing this behavior on Windows with 6.8.3, was there a QTBUG tracking this behavior and/or fix that may have more information?

@Christian-Ehrlicher Thank you. I found that after I add -DCMAKE_BUILD_TYPE=Debug when I build qoci the qsqlocid.dll, etc. are built and installed, then the problem can be fixed

@Christian-Ehrlicher I'm using gcc 8.5.0 I honestly can't tell where in the code the error is occuring because the output is so long. I've been building this applciation for years using various versions of Qt, but I haven't seen these errors before. It builds without error under Qt 6.6.3. I can try a simple program to see if I also get the errors there.
