Struct WidgetNode

pub struct WidgetNode {
    pub widget: Rc<RefCell<dyn Widget>>,
    pub children: Vec<WidgetNode>,
}

Node in the widget hierarchy.

A WidgetNode owns a concrete widget instance and zero or more child nodes. Events are dispatched depth‑first and drawing occurs in the same order. This mirrors the behaviour of common retained‑mode UI frameworks.

Fields

widget: Rc<RefCell<dyn Widget>>

The widget instance held by this node.

children: Vec<WidgetNode>

Child nodes that make up this widget’s hierarchy.

Implementations

impl WidgetNode

pub fn dispatch_event(&mut self, event: &Event) -> bool

Propagate an event to this node and its children.

Returns true if any widget handled the event.

pub fn draw(&self, renderer: &mut dyn Renderer)

Recursively draw this node and all child nodes using the given renderer.
