IndirectTouchInputModifierNode

Interface

Common

@ExperimentalIndirectTouchTypeApi
interface IndirectTouchInputModifierNode : DelegatableNode

Implement this interface to create a Modifier.Node that can intercept indirect touch input events.

The event is routed to the focused item. Before reaching the focused item, onPreIndirectTouchEvent is called for parents of the focused item. If the parents don't consume the event, onPreIndirectTouchEvent is called for the focused item. If the event is still not consumed, onIndirectTouchEvent is called on the focused item's parents.

Functions

fun onIndirectTouchEvent(event: IndirectTouchEvent): Boolean

This function is called when an IndirectTouchEvent is received by this node during the upward pass. While implementing this callback, return true to stop propagation of this event. If you return false, the generic motion event will be sent to this IndirectTouchInputModifierNode's parent.

fun onPreIndirectTouchEvent(event: IndirectTouchEvent): Boolean

This function is called when an IndirectTouchEvent is received by this node during the downward pass. It gives ancestors of a focused component the chance to intercept an event. Return true to stop propagation of this event. If you return false, the event will be sent to this IndirectTouchInputModifierNode's child. If none of the children consume the event, it will be sent back up to the root using the onIndirectTouchEvent function.
