Trait PointerInputNode 

pub trait PointerInputNode: ModifierNode {
    // Provided methods
    fn on_pointer_event(
        &mut self,
        _context: &mut dyn ModifierNodeContext,
        _event: &PointerEvent,
    ) -> bool { ... }
    fn hit_test(&self, _x: f32, _y: f32) -> bool { ... }
    fn pointer_input_handler(&self) -> Option<Rc<dyn Fn(PointerEvent)>> { ... }
}

Marker trait for pointer input modifier nodes.

Pointer input nodes participate in hit-testing and pointer event dispatch. They can intercept pointer events and handle them before they reach the wrapped content.

Provided Methods

fn on_pointer_event( &mut self, _context: &mut dyn ModifierNodeContext, _event: &PointerEvent, ) -> bool

Called when a pointer event occurs within the bounds of this node. Returns true if the event was consumed and should not propagate further.

fn hit_test(&self, _x: f32, _y: f32) -> bool

Returns true if this node should participate in hit-testing for the given pointer position.

fn pointer_input_handler(&self) -> Option<Rc<dyn Fn(PointerEvent)>>

Returns an event handler closure if the node wants to participate in pointer dispatch.
