Programatic way to close main window

[runrc]

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

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()

[kkoreilly]

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.

Unfortunately, this causes a data race, I have raised a bug #1267
