next_hit_z: usize

node_index: HashMap<NodeId, usize>

Implementations

impl Scene

pub fn new() -> Self

pub fn diagnostics(&self) -> &RenderDiagnostics

pub fn push_hit( &mut self, node_id: NodeId, capture_path: &[NodeId], geometry: HitGeometry<'_>, shape: Option<RoundedCornerShape>, click_actions: impl IntoIterator<Item = ClickAction>, pointer_inputs: &[Rc<dyn Fn(PointerEvent)>], )

Adds an interactive target in draw order, ignoring targets without handlers.

pub fn clear_hits(&mut self)

Removes all hit targets and releases their handlers while retaining vector capacity.

pub fn replace_graph(&mut self, graph: RenderGraph)

Trait Implementations

impl Default for Scene

fn default() -> Self

Returns the “default value” for a type.

impl HitGraphSink for Scene

fn push_hit( &mut self, node_id: NodeId, capture_path: &[NodeId], geometry: HitGeometry<'_>, shape: Option<RoundedCornerShape>, click_actions: &[Rc<dyn Fn(Point)>], pointer_inputs: &[Rc<dyn Fn(PointerEvent)>], )

impl RenderScene for Scene

type HitTarget = HitRegion

fn clear(&mut self)

fn hit_test(&self, x: f32, y: f32) -> Vec<Self::HitTarget>

Performs hit testing at the given coordinates. Returns hit targets ordered by z-index (top-to-bottom).

fn find_target(&self, node_id: NodeId) -> Option<Self::HitTarget>

Finds a hit target by NodeId with fresh geometry from the current scene.

fn collect_retained_visual_observation_nodes( &self, nodes: &mut HashSet<NodeId>, ) -> bool

Replaces the set with retained visual observation owners, preserving its capacity. Returns whether the scene provides this information.

fn hit_test_nodes(&self, x: f32, y: f32) -> Vec<NodeId>

Returns NodeIds of all hit regions at the given coordinates. This is a convenience method equivalent to hit_test().map(|h| h.node_id()).
