```kotlin
@JvmDefaultWithCompatibility
interface OnGloballyPositionedModifier : Modifier.Element
```


A modifier whose `onGloballyPositioned` is called with the final LayoutCoordinates of the Layout
when the global position of the content may have changed. Note that it will be called after a
composition when the coordinates are finalized.


## Functions

```kotlin
fun onGloballyPositioned(coordinates: LayoutCoordinates)
```


Called with the final LayoutCoordinates of the Layout after measuring. Note that it will be
called after a composition when the coordinates are finalized. The position in the modifier
chain makes no difference in either the `LayoutCoordinates` argument or when the
`onGloballyPositioned` is called.



## Code Examples

### OnGloballyPositioned
```kotlin
@Composable
fun OnGloballyPositioned() {
    Column(
        Modifier.onGloballyPositioned { coordinates ->
            // This will be the size of the Column.
            coordinates.size
            // The position of the Column relative to the application window.
            coordinates.positionInWindow()
            // The position of the Column relative to the Compose root.
            coordinates.positionInRoot()
            // These will be the alignment lines provided to the layout (empty here for Column).
            coordinates.providedAlignmentLines
            // This will be a LayoutCoordinates instance corresponding to the parent of Column.
            coordinates.parentLayoutCoordinates
        }
    ) {
        Box(Modifier.size(20.dp).background(Color.Green))
        Box(Modifier.size(20.dp).background(Color.Blue))
    }
}
