Struct WidgetNode 

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

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§

Source§

impl WidgetNode

Source

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.

Source

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

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