Hey guys, I wrote a .scrollable(zoomScrollState, Orientation.Vertical) modifier, but I need the mouse position in order to zoom around where the mouse is. How can I get mouse position in scrollable modifier?

MouseInfo.getPointerInfo().getLocation()

You might need to use SwingUtilities.convertPointFromScreen to convert that to the coord system of your component

@Kirill Grouchnikov Thank you! The convertPointFromScreen has a component parameter, how can I retrieve the component from a compose element in my function?

Maybe I should just use onPointerEvent(PointEventType.Scroll) as that seems a more desktop oriented API (I can get a reference to the awt mouse event)

[Kirill Grouchnikov]

Probably the OnGloballyPositionedModifier would be better suited for the conversion then.

I need to know the mouse position at the time the user does scroll though, so how would that work with onGloballyPositioned?

That one is for translating the mouse location from screen to your composable
