Even if you could I don’t think you would want to do it this way. Have a go routine sleep on a channel. Post to the channel from the native code.
Let your command loop run on any thread and synchronize via a channel the calls to/from native. The os event loop doesn’t need to run on main - it just needs to be locked to a thread - use a native thread - and post the os events to a channel. Probably easiest to export a simple Go postToEventChannel() and have the native use this. > On Jan 3, 2020, at 2:18 PM, bucha...@gmail.com wrote: > > > I've been getting by with a version of this that sends commands (closures) to > a loop on the main thread: > https://github.com/buchanae/ink/blob/2af8781a960a0351b6b6b7ca23d81ae5c43535ec/win/window.go#L55 > > And here is where it pops those commands, and also integrates with the OS > event loop: > https://github.com/buchanae/ink/blob/2af8781a960a0351b6b6b7ca23d81ae5c43535ec/win/window.go#L163 > > But, I'm still not satisfied.
