Struct WidgetNode 

pub struct WidgetNode {
    pub id: WidgetId,
    pub parent: Option<WidgetId>,
    pub children: Vec<WidgetId>,
    pub rect: Rect,
    pub z_index: i32,
    pub hit_testable: bool,
    pub focusable: bool,
    pub dirty: bool,
    pub clip_rect: Option<Rect>,
    pub label: Option<String>,
}

A single node in a WidgetTree.

Fields

id: WidgetId

This node’s stable identifier.

parent: Option<WidgetId>

Parent node, or None for the root.

children: Vec<WidgetId>

Child nodes in paint (back-to-front) order.

rect: Rect

Layout rectangle in the coordinate space of the tree’s root.

z_index: i32

Paint order among siblings; higher draws on top.

hit_testable: bool

Whether this node participates in hit testing (false = pass-through).

focusable: bool

Whether this node can receive keyboard focus.

dirty: bool

Dirty flag: layout or paint needs recomputation.

clip_rect: Option<Rect>

Optional clip rectangle, in the tree’s root coordinate space. When set, content (and hit testing) is constrained to the intersection of rect and this clip. None means inherit the parent clip / no clipping.

label: Option<String>

Optional debug/role label (used by a11y and diagnostics).

Implementations

impl WidgetNode

pub fn new(id: WidgetId, rect: Rect) -> Self

Construct a node with the given id and rectangle. Defaults: hit-testable, not focusable, z_index 0, dirty.

pub fn with_clip(self, clip: Rect) -> Self

Builder-style setter for clip_rect.

Trait Implementations

impl Clone for WidgetNode

fn clone(&self) -> WidgetNode

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WidgetNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result
