PressInteraction.Cancel is sent on mouse press and drag outside surface about compose-multiplatform

[eymar]

The observed behaviour is the same on Android, so it's inherited from Jetpack Compose.

From InteractionSource docs:

A common use case is androidx.compose.foundation.indication, where androidx.compose.foundation.Indication implementations can subscribe to an InteractionSource to draw indication for different Interactions, such as a ripple effect for PressInteraction.Press and a state overlay for DragInteraction.Start.

So using InteractionSource is not the best way to derive the actions on buttons (clicked, double-clicked, etc). Listening to Pointer Events is a better choice for this.

JFYI: When dragging after PointerEventType.Press there is also PointerEventType.Exit event before PointerEventType.Release.

Considering the visual effects manifested by a Button when I interact with it, I assume the behaviour of InteractionSource is correct. If your use case requires not visual effects, but some other logic probably PointerEvents is better option.

Could you please share more details about your use case?
