How can I set the `loop` variable to global ? about quamash HOT 5 CLOSED

the standard way is to use asyncio.get_event_loop(), but you could also set a variable on application or whatever.

Python doesn't have real "global" variables, the most it has is module global variables, so if you want to access main.loop from the mainwindow module, do from .main import loop in mainwindow.py.

The global and nonlocal keywords are for writing to globals and nonlocals in python not reading from them (though they can help with readability when accessing a variable from a nested scope).

Also this is a python question not really relevant to quamash more appropriate to stackoverflow (not that I mind).

You may wish to review the python scoping rules and packages and modules

Thanks a lot.

I think the asyncio.get_event_loop() function may help me solving the problem.

Annotatiion:

asyncio.get_event_loop() can give us the event_loop object, however, it only works in main-thread since the event loop must be run in the main thread.

As a result, if you want to get event_loop object in other thread, maybe you need to set a variable on application.

To schedule a callback from a different thread, the AbstractEventLoop.call_soon_threadsafe() method should be used.
Example: loop.call_soon_threadsafe(callback, *args)
You can not use asyncio.get_event_loop to get loop object here.

Correct, there's a feature card somewhere to make a QEventLoop policy for better threading support.

I don't have much motivation to work on quamash these days though, so it's pretty unlikely to get done.
