Is there a way to have some kind of zIndex working outside of a single parent or some way to handle priority for clickable when there's overlap ?

zIndex

only works wthin the parent and there isn't any other way to move a child outside of its parent's

zIndex

. You would have to lift the child out of the parent or lift the entire parent. While I don't think

clickable

offers the ability to handle overlapping views, you can do it with the pointer system. You can do something like this to handle it similar to `onInterceptTouchEvent`:

Modifier.pointerInput(onClick) {
  forEachGesture {
    awaitPointerEventScope {
      var down: PointerEvent
      do {
        down = awaitPointerEvent(PointerEventPass.Initial)
      } while (!down.all { it.changedToDown() } )
      down.consumeDownChange()
      do {
        val up = awaitPointerEvent(PointerEventPass.Initial)
      } while (!up.all { it.changedToUp() })
      onClick()
    }
  }
}

You can look at some of the internal functions for some robust handling. For example

awaitFirstDownOnPass

.

So that something I need to use on the "lower" clickable to intercept before the "higher" one ?

That's the idea. I think it will work.

Ok thanks, no it's a parent fastscroll bar with a large touch zone that for 1,5 seconds before disapear can overlap a button, trigger an unwanted scroll. I'll try but I think it should be ok.

George may I ask you to have a look at this? I've a similar need, but I am building a vertical scroll view that reveal hidden header / footer when scrolled. I'm sorry to bother you https://kotlinlang.slack.com/archives/CJLTWPH7S/p1670348015304799?thread_ts=1670348015.304799&cid=CJLTWPH7S
