In case anyone comes across this thread, like I did, I had this issue trying to run my app on a Mac M1 (arm64) on an iOS simulator. Because Qt's iOS simulator kits only support x86_64, it builds for the 'Rosetta' simulators. As far as I'm aware, this has been the case since Qt started supporting Apple Silicon. The important piece of info is that there was a mistake in some of the Qt 6.8 builds - they included arm64 ffmpeg libraries for iOS simulator whereas they should have included x86_64 ones. This affects Qt 6.8.3 and possibly earlier versions. It was fixed in Qt 6.8.4. I encountered the exact same errors and warnings as the OP, using Qt 6.8.3. The problem disappeared by switching to Qt 6.8.4.

i have overridden the paint event to do what i need. thank you very much for your help! it works now

Using QT Designer might be the simpler route if the main goal is to keep the workflow smooth with Python. QT Design Studio projects often need manual adjustments before they run properly under PySide6.

I have had a problem when editing the names.py manually in that Squish no longer recognises the object. I now delete the object and re-enter it after using the picker tool then add to object map. Not sure if this is what you meant, but hopefully this helps

@veerbhan I would recommend you to add with us (Me and Lehomar2vinci).

@stash22 said in Why does QTextStream::pos() return -1 while reading a file line-by-line in Qt?: m_readNmeaTextStream.pos() becomes -1. The documentation states this: https://doc.qt.io/qt-6/qtextstream.html#pos

Sto sviluppando un software gestionale e mi collego ad un database mysql tramite ODBC perché non riesco a collegare mysql a qt. Uso qmake e non cmake. Qualcuno mi può aiutare ?
