问题 I have a complex function in my MainWindow class which periodically runs queries and changes attributes and data of the widgets. Since it can take a long time on the main thread, the GUI can appear to freeze. So I created a GUIUpdater class on another thread to do the periodic operation. I based it on the solution here, which shows how to update a QLabel from another thread: Qt - updating main window with second thread But that solution requires defining a connection. With a complex function

问题 First of all, I'm currently migrating my source code from PyQt5 to PySide2 which requires me to change some of the syntaxes.

I have checked countless examples and tutorials, but the fact that the progressbar shows up in a pop-up window seems to make everything harder. I believe what I want is a rather simple thing but I keep failing at it and I ran out of ideas. I have an example of what I am trying to achieve, which is based on
