onPointerEvent gets triggered even when its Composable is covered by another one. I have a dialog displaying on top of an element, but clicking on the dialog also interacts with the element behind the dialog. What would be the proper way to handle this? I expected events to not get delivered if it's covered by something.

I fixed this by also adding a dummy onPointerEvent that does nothing on the dialog, which seems to consume the event so that it doesn't reach the element behind it.

Reproducer please

When scrolling over the green area events get printed, even though the grey area that has the onPointerEvent is covered.

Repro.kt.cpp

Scroll events are supposed to do that. Otherwise you would not be able to scroll a container with any content inside it.

But not in a dialog

Same for Move events though, I guess it's also intended?

[Alexander Maryanovsky]

Mouse move I think no. Not sure.

Although… how would a button with text work if not?

[Alexander Maryanovsky]

So I guess that’s also expected

And same for Press events, which is certainly not ideal 😄

Since I'm ending up clicking stuff that's behind and not visible

Yeah
