Programatic way to close main window

[runrc]

What is the programmatic way to close the main window, possibly from another goroutine?

[runrc]

Use system.TheApp.Quit()

Yes, to close all windows, you can call system.TheApp.Quit or core.TheApp.Quit (core.TheApp embeds system.TheApp). If you only want to close a specific window/scene, you can call Scene.Close (ex: myWidget.Scene.Close() to close the Scene that contains myWidget).

What is the recommended way to close the main window from another goroutine?
I have a signal handler that catches interrupt signals and needs to close the main window.
However, I get a data race, when I call system.TheApp.Quit()

You could try surrounding your system.TheApp.Quit() call with AsyncLock and AsyncUnlock calls on a widget in the main window; see https://www.cogentcore.org/core/basics/async.
