I am not sure how to adapt the code

val userPreference = UserPreference()

Window(
  size = userPreference.windowSize,
  resizable = true,
  title = "Test",
  events = WindowEvents(onResize = userPreference::onWindowResize)
) {
  App(userPreference)
}

to the new Window api. It looks like I can use

val state = rememberWindowState(size = userPreference.windowSize)

, but I am not sure how to call

onWindowResize

when

state.size

changes...

It is a bit more code in a new API 🙂

val state = rememberWindowState()

Window(state) {

}

LaunchedEffect(state) {
    snapshotFlow { state.size }
        .onEach(::onWindowResize)
        .launchIn(this)

    snapshotFlow { state.position }
        .filterNot { it.isInitial }
        .onEach(::onWindowRelocate)
        .launchIn(this)
}

(similar to listening the other hoisted states, like LazyListState)

thank you. I will try this. I don't mind that it is more code. It is just that I had no clue how to do it and clearly it is not trivial. I carefully read the tutorial for this new api (https://github.com/JetBrains/compose-jb/tree/master/tutorials/Window_API_new) but I couldn't find a description about it.

description about it

We forgot about it and added it recently. Thanks for bringing this 🙂

No problem. I guess that is what using cutting edge tech means... Glad to be able to help as well by providing feedback.

Wow, thanks for noticing this, I changed the tutorials. Yes, the right approach is to write this in

Window

scope. Because when we close the window - we will cancel all launched inside

Window

coroutines. If we launch coroutines inside

application

- we can't cancel them.
