Project Verona: Fearless Concurrency for Python

The tricky part is coming back onto the UI thread when the background work finishes. Your transcription thread has to somehow trigger the UI work to be done on the UI thread.

It seems the way to do it in Qt is with signals and slots, emitting a signal from your QThread and binding it to a slot in the UI thread, making sure to specify a "queued connection" [1]. There's also a lower-level postEvent method [2] but people disagree [3] on whether that's OK to call from a regular Python thread or has to be called from a QThread.

So I would try doing it with Qt's thread classes, not with concurrent.futures.

Although keep in mind that the callback will be "called in a thread belonging to the process" (say the docs), presumably some thread that is not the UI thread. So the callback needs to post an event to the UI thread's event queue, where it can be picked up by the UI thread's event loop and only then perform the UI updates.

I don't know how that's done in Pyside, though. I couldn't find a clear example. You might have to use a QThread instead to handle it.

Unfortunately we don't have that kind of AI. We only have the useless kind.

Handing over the data of EU citizens to be exploited by US companies is not "innovation in the EU".
