GraphEventMap<T>

矢量图形类覆盖物（折线、多边形、圆等）共享的事件名与事件对象类型映射。各图形类的 EventMap（如 PolylineEventMap）均由此派生

interface GraphEventMap<T = Overlay> {
    click: OverlayMouseEvent<T>;
    dblclick: OverlayMouseEvent<T>;
    editend: GraphEditEvent<T>;
    editstart: GraphEditEvent<T>;
    lineupdate: GraphLineUpdateEvent<T>;
    linevertexdel: GraphVertexEvent<T>;
    linevertexdragend: GraphVertexEvent<T>;
    linevertexdragging: GraphVertexEvent<T>;
    linevertexdragstart: GraphVertexEvent<T>;
    mousedown: OverlayMouseEvent<T>;
    mousemove: OverlayMouseEvent<T>;
    mouseout: GraphMouseOutEvent<T>;
    mouseover: OverlayMouseEvent<T>;
    mouseup: OverlayMouseEvent<T>;
    remove: OverlayBaseEvent<T>;
    rightclick: OverlayMouseEvent<T>;
    rightdblclick: OverlayMouseEvent<T>;
}
