Is Slint's integration with Boost.Asio feasible ?

[mitsubishirgb]

Can I seamlessly share Boost.Asio’s io_context with Slint’s event loop, so I can use coroutines efficiently without polling or spawning an extra thread for non-blocking operations?

If that’s possible, could someone provide guidance or an example on how to set it up?

I'm not familliar with Boost.asio, but the easiest might be to spawn another thread for it, and use slint::invoke_from_event_loop to communicate with the main thread.

The ideal solution would be calling io_service::poll from a callback that calls slint::invoke_from_event_loop. But I'm not sure if boost provides such callback. (as a said i'm not really familiar with it)

An harder solution is to re-implement a slint::platform::Platform that can drive the eventloop using the one from boost asio

An example of that is https://github.com/KDABLabs/mecaps/ and the platforms examples in https://github.com/slint-ui/slint/tree/master/examples/cpp
