You can do this easily by using the static .processEvents () function on the QApplication class. Simply add a line like the following, somewhere in your long-running code block: python QApplication.processEvents () For example long running code time.sleep we could break that down into 5x 1-second sleeps and insert the .processEvents in between.

Doing a PyQt vs PySide comparison at the time of the split (2009) would have shown that both were roughly equal. However as the time went on, the development of PySide lagged behind PyQt significantly. Following the release of Qt5, PyQt5 (the python binding for Qt5) was released in 2016. In contrast, it took PySide an extra 2 years (2018) to. May 13, 2021 · For example, if you replace QtWidget with QPushButton.

That is going to stop Python from releasing these objects. Meanwhile, you are seem to be trying to create new QApplication. And you're getting RuntimeError: Please destroy the QApplication singleton before creating a new QApplication instance. I wonder whether the retained references are contributing to/clouding the issue.
Also looking in the HDK we don't expose the QT_Utils class which is probably a good thing. You should be able to access the app stylesheet similarly in C++ like so: QApplication::instance()->styleSheet() Could you maybe give us a code sample (use my code sample in the first post if you want) as to how to interact with QApplication?.
