That's really helpful. thank you.

After countless hours of debugging solution was really REALLY obscure. I had my QURL for QQmlApplicationEngine set to a loading screen then creating the App component from there. Qt really did not like this. returning the Original App.qml as my main URL and then running engine.load for my loading screen. engine.load(url); engine.load("qrc:/qt/qml/ExplorariumContent/LoadingScreen.qml"); TLDR: I used a very buggy method to load the app which caused ListView to freak out. Component { id: appComponent App {} } Connections { target: loadingScreenManager function onLoadApp() { var appWindow = appComponent.createObject(null) appWindow.effect.start() Qt.callLater(function() { root.close() }) } }

Alright I finally solved the issue. I added this to my CMakeLists.txt set(sources main.cpp) qt_add_resources(sources res.qrc) And ${sources} in the qt_add_executable list So now this is on top of my CMakeLists.txt set(sources main.cpp) qt_add_resources(sources res.qrc) qt_add_executable(4-WindowDifference WIN32 MACOSX_BUNDLE main.cpp mainwindow.cpp mainwindow.h res.qrc ${sources} )

Ok, thanks all. Looks like the application I downloaded was broken. The distributor didn't include everything that would allow it to run on a basic system. Thanks to everybody for your answers.

@SGaist I know it's a macro, I've already tried expanding it myself; the result was exactly the same. I'll try to analyze the generated code, thanks.

@blossomsg There's no reason for that slot to be in the model. Depending on how you want to integrate that with Maya, create your own custom view on top of the model that will translate that information in whatever is needed for Maya. A "view" does not mandatory mean a tree or a table, it's really whatever uses the model as a source of information.

I can't test this ancient version but would guess you installed a static Qt version. Therefore all is linked directly into your executable which explains the size.

Well, I am surprised to hear that someone might want to exclude unit tests. The project is going to grow. It always does. It's not possible to remember every little aspect of the project. And if the team changes and someone new joins, how on earth are they going to make sure there is no butterfly effect in a huge and old codebase that they do not know? That's sad. It reminds me of a similar situation I had a long time ago as a young programmer, saying that we need CI/CD and unit tests.

I faced the same behavior, which was unexpected and undocumented. I was debugging Qt, and at the end there is the following fallback in their code. int registerHelper() const { if (d_ptr) { if (int id = d_ptr->typeId.loadRelaxed()) return id; return registerHelper(d_ptr); } return 0; } int QMetaType::registerHelper(const QtPrivate::QMetaTypeInterface *iface) { Q_ASSERT(iface); auto reg = customTypeRegistry(); if (reg) { return reg->registerCustomType(iface); } return 0; } qtbase\src\corelib\kernel\qmetatype.cpp

At a glance, it's not obvious that the xcb QPA (qtbase/src/plugins/platforms/xcb/xcb.pro) plugin won't work with recent macOS if the requisite supporting libraries and headers are present. Homebrew lists a few potential matches for "brew search xcb", including "libxcb".

@JacobNowitsky What's so hard about creating a PCH file like // myApp_pch.h #include <QApplication> #include <QWidget> and then enable the PCH support depending on your build system?! BTW: The video even explains how to set this up... so what do you mean?!

Got it. By-value lambda capture of const reference...

@Rockerz said in custom plot: @JonB I tried but I got tar.gz file extracted and add these file (qcustomplot.h, qcustomplot.cpp) I'm getting many unresolved errors where to get the dll file ? I searched and I download from official website only tar files I found (https://www.qcustomplot.com/index.php/introduction) QCustomPlot doesn’t provide a DLL — you must compile the .cpp/.h files into your project. Just add them to your Qt project and rebuild; no external DLL needed.

Hi, Did you already check QVideoFrameFormat and its friends to check whether they fit your need somehow ?

@SGaist Thanks for the reply, they didn't provide the .lib files in the source code, so I had to generate them myself. I was able to find https://wiki.videolan.org/GenerateLibFromDll explaining how to do it and got the application to run now, thanks!
