Double event loop possible?

[ethanpil]

A simplification of my application is a web server controlled by the Rumps menu. I cannot combine Rumps main loop and asyncio (or any other similar web server lib)'s event loop. In a way that doesn't lock up the Rumps GUI.

Based on some of the examples below, (I am not much of a MacOS internals person) do you think it would be possible to add some functionality to integrate two event loops in some sort of co-routine with Rumps?

For more info, please look here: https://www.reddit.com/r/Python/comments/33ecpl/neat_discovery_how_to_combine_asyncio_and_tkinter/ https://github.com/harvimt/quamash https://pypi.org/project/async_gui/0.1.1/ https://docs.python.org/3/library/asyncio-task.html

Do you have example code you have been working with? I'd like to play around with it.

I have the same question.

I would like to use wxWidgets to create some windows, but wxWidgets event loop is brought up by app.MainLoop() and rumps also requires a App().run(). These two calls are all blocking.

Investigate a bit on rumps.App().run(): It calls AppHelper.runEventLoop(), which calls NSApp().run(), which is blocking.

Not sure how to implement this...

BTW, thanks for creating this handy library.

Yeah.. App().run() (rumps) and asyncio's event loop don't play nice together. Tried putting rumps in a Python thread, I got:

objc.error: NSInternalInconsistencyException - NSWindow drag regions should only be invalidated on the Main Thread!

I think using two different UI packages generally isn't advised.

My original issue was in regards to asyncio for web server. Same problem. I'm sorry I haven't posted up the code. I will find that and get it up soon. Thanks for your patience.

I have a situation where this would also be handy. I'm attempting to use the python library @ https://github.com/jonathanslenders/ui24r-client to create a system tray app that monitors the mute status of channels on a mixer. The library is an asyncio-based client. The goal would be to use the client to manipulate the title of the menu bar app. I have an existing solution that updates every second using xbar, but I'm hoping to find a solution that provides real-time feedback.

I haven't tried this, but you should be able to run the asyncio loop in a thread different from the main thread. See for example this gist: Python asyncio event loop in a separate thread
