      <div className="flex gap-2 mt-3">
        <Button size="sm" variant="outline" onClick={handleDecline}>
          拒绝
        </Button>
        <Button size="sm" onClick={handleAccept}>
          接受
        </Button>
      </div>
    </div>
  );
}

11. 组件通信模式

11.1 Props 向下传递

父组件通过 Props 向子组件传递数据和回调。

// 父组件
<StoryboardItem
  storyboard={storyboard}
  isSelected={selectedId === storyboard.id}
  onSelect={handleSelect}
/>

// 子组件
function StoryboardItem({ storyboard, isSelected, onSelect }) {
  return (
    <div onClick={() => onSelect(storyboard.id)}>
      {/* ... */}
    </div>
  );
}

11.2 全局状态（Zustand）

跨组件共享状态。

// Store
const useEditorStore = create((set) => ({
  selectedId: null,
  setSelectedId: (id) => set({ selectedId: id }),
}));

// 组件 A
function StoryboardPanel() {
  const selectedId = useEditorStore((s) => s.selectedId);
  // 使用 selectedId
}

// 组件 B
function PreviewPanel() {
  const selectedId = useEditorStore((s) => s.selectedId);
  // 使用同一个 selectedId
}

11.3 事件总线（可选）

用于松散耦合的组件通信。

// src/utils/eventBus.ts
type EventCallback = (...args: any[]) => void;

class EventBus {
  private events: Map<string, EventCallback[]> = new Map();
  
  on(event: string, callback: EventCallback) {
    const callbacks = this.events.get(event) || [];
    callbacks.push(callback);
    this.events.set(event, callbacks);
    
    return () => this.off(event, callback);
  }
  
  off(event: string, callback: EventCallback) {
    const callbacks = this.events.get(event) || [];
    this.events.set(event, callbacks.filter((cb) => cb !== callback));
  }
  
  emit(event: string, ...args: any[]) {
    const callbacks = this.events.get(event) || [];
    callbacks.forEach((cb) => cb(...args));
  }
}

export const eventBus = new EventBus();

// 使用
// 发送
eventBus.emit('storyboard:created', newStoryboard);

// 监听
useEffect(() => {
  return eventBus.on('storyboard:created', (storyboard) => {
    // 处理
  });
}, []);

11.4 Context（局部共享）

用于特定子树的状态共享。

// TimelineContext.tsx
const TimelineContext = createContext<TimelineContextValue | null>(null);

export function TimelineProvider({ children }: { children: React.ReactNode }) {
  const [zoom, setZoom] = useState(1);
  const [scrollPosition, setScrollPosition] = useState(0);
  
  return (
    <TimelineContext.Provider value={{ zoom, setZoom, scrollPosition, setScrollPosition }}>
      {children}
    </TimelineContext.Provider>
  );
}

export function useTimeline() {
  const context = useContext(TimelineContext);
  if (!context) {
    throw new Error('useTimeline must be used within TimelineProvider');
  }
  return context;
}

// 使用
<TimelineProvider>
  <TimelinePanel />
</TimelineProvider>
