PointCollection 点集合类 ​

判定 ​

isPointCollection() ​

typescript
const isPointCollection: (tar: any) => tar is PointCollection

属性 ​

redonlay id: string 唯一标识 ​

size: number 子元素数量 ​

show: boolean 是否显示 ​

label: HtmlLabel ​

方法 ​

add 添加点 ​

typescript
add(options: PointCollectionOptions['addOptions']): PointPrimitive

type PointCollectionOptions = {
  addOptions: {
    /** 唯一标识 */
    id?: string;
    /** 位置 */
    position: Point3d | [number, number, number?];
    /** 显示消失 */
    show?: boolean;
    /** 点大小 */
    size?: number;
    /** 点颜色 */
    color?: MapColor;
    /** 描边宽度 */
    outlineWidth?: number;
    /** 描边颜色 */
    outlineColor?: MapColor;
    labelOffset?: [number, number];
    /** 近距离 */
    near?: number;
    /** 远距离 */
    far?: number;
    /** 近距离缩放 */
    nearScale?: number;
    /** 远距离缩放 */
    farScale?: number;
    property?: Record<string | symbol, any>;
  };
};

get 获取 ​

  • id 子元素id
typescript
get(id: string): PointPrimitive | undefined

setPoint 设置改变子元素样式 ​

typescript
setPoint(id: string, options: Partial<Omit<PointCollectionOptions['addOptions'], 'id' | 'near' | 'far' | 'nearScale' | 'farScale' | 'property'>>): PointPrimitive | undefined

on 事件注册 ​

  • 两个函数重载
typescript
 on(
    type: 'mouseMove',
    listener: (tar: [PointCollection, PointPrimitive | undefined], mark: 'in' | 'out', Even: MouseMoveEvent) => void
  ): PointCollection;
  on(type: PickType, listener: (tar: [PointCollection, PointPrimitive | undefined], mark: 'in' | 'out', Even: PickEvent) => void): PointCollection;

off 事件移除 ​
