When omitted, a default AABB intersection check against the area rect is used. + +The method returns the `TRect` produced by `fn`, so you can use it for further layout calculations. + +#### How It Works + +1. **Registration** — `eventedArea()` is called during `render()`. It executes `fn(state)` (which draws on the canvas and returns the rect), stores the area with its handlers. +2. **Local state** — the framework maintains `hovered` state per area key. When the hover state changes, the component automatically re-renders so `fn` receives the updated `{ hovered }`. +3. **Cleanup** — all areas are cleared in `willRender()` before each render cycle, so they always match the current visual state. The hover key persists across renders. +4. **Event dispatch** — when `_fireEvent` is invoked on the component, it checks each registered area: if the area has a handler for the event type and `onHitBox` (or the default AABB check) confirms a hit, the handler fires. +5. **Listener detection** — `_hasListener` accounts for evented areas, so events bubble correctly to components that only use evented areas without conventional `addEventListener` calls. + +#### Usage Examples + +**Basic: two clickable zones on a block** + +```typescript +class MyBlock extends CanvasBlock { + protected render() { + super.render(); + + // Top-left 50×50 "edit" button — uses hovered state for visual feedback + this.eventedArea( + ({ hovered }) => { + const ctx = this.context.ctx; + ctx.fillStyle = hovered ?
