I'm trying to make a Composable

Box(Modifier.zIndex()...

relate to the centre coordinates of that Box. How do I reference the item's own properties in its own Modifiers?? Thanks! 😵

relate to the centre coordinates? Could you elaborate?

Yes, I want the zIndex to be the Box's own

Canvas.center.x

Ah those are two separate dimensions so it made no sense to me at first.

Sorry! 😀

There are a couple ways to achieve this but it depends on what you're trying to do.

I want the display order of objects to be dependent on its lateral placement.

You can use

Modifier.onGloballyPositioned {}

to get the coordinates after composition has happened.

Oh! OK, that's a new thing for me. I will try that.

Oh, in that case instead of trying to observe the properties of the item it may be more appropriate to set them yourself. Since you might not want a frame of lag between the zIndex value and the x value.

Assign it to a variable in the {} ?

Sure

Hmm. Ok, I'll try that.
