Apologies - can anyone explain what I need to do to fix this message: Functions which invoke @Composable functions must be marked with the @Composable annotation - I can't mark main as composable; I tried moving the body of my application into a separate @Composable function, but I feel like I'm missing some key understanding here.

Compose for Desktop runs inside the normal Java Swing system, currently. the main function is literally just the standard entry-point to a JVM application, and there’s nothing specific about it that makes it Composable. You have to bootstrap the Swing/Compose toolkit yourself with the Window() function as shown in the “getting started” documentation https://github.com/JetBrains/compose-jb/tree/master/tutorials/Getting_Started

Doh! But's remarkable how much code you can write - and have work - without doing this... I've been playing with this for days with my call to `Window()`about 40 lines into the main function!

My general debugging process on this is to look up the hierarchy to see if I’m calling something in a non-Composable context. Though I don’t blame you because sometimes it’s not obvious and requires trial-and-error.

And yeah, in the example above Window is the root composable in main
