@YuXin said in QProgressBar has rendering errors or does not render at all: The timing of the startTimer does not affect the issue. In principle an odd number is more likely to trigger QDateTime::currentMSecsSinceEpoch() % 2 being true on alternates than always being either true or false. the purpose of this if statement is exactly as you assumed: to randomly trigger setValue Exactly. And for that you would be much better off using a random number than your potentially-deterministic QDateTime::currentMSecsSinceEpoch() % 2 . Anyway, I am sorry if we digressed. I intended this to be a brief comment, especially for posting for others to reproduce.

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
