How can I listen to whether a Window is active/focused as Compose state? The window.isActive property is accessible but I'm looking for a way to listen for changes in it.

You can use the AWT/Swing APIs:

window.addWindowListener(object: WindowAdapter() {
    override fun windowActivated(evt: WindowEvent?) { 
        ...
    }
})

Actually, I found it's exposed in the Compose world through LocalWindowInfo, so no need to use the AWT APIs.

Yes, that’s better

Although I’m not sure of the difference between “focused” and “active”.
