应用层主类，用于获取底层相关接口，以及监听底层方法

    初始化sview

initSView(labelId) {
	this.sviewFrame = SView.createSViewObject(SView, "FrameMain", labelId);
	if (renderType !== RenderType.Server) {
		this.sviewFrame.createCanvas(labelId);
		this.sviewFrame.getViewer().initEventListener();
	}
	//添加对Frame层的消息订阅
	M3D.Utility.M3DMessageCenter.getCenter().subscribe(this, this.sviewFrame);
	return this.sviewFrame;
}

    消息监听处理可参考API文档中SView消息机制以及原文件

update(msg) {
    // console.error(`我是[sview]，收到了新消息,内容为： ${msg.state}`);
    switch (msg.type) {
        //修改右键菜单是否可用(msg.state= "true")
        case "ChangeRightMenuClick":
            break;
        case "MoveTypeCommand":
            break;
        case "PlayAnimationCommand":
            break;
        case "CreateClipPlaneCommandView":
            break;
        case "ShapeSetCommandView":
            break;
        case "PropertyCommandView":
            break;
        case "CollisionCommand":
            break;
        case "ChangeFaceColor":
            break;
        case "VolumeWeightCommand":
            break;
        case "CollisionCommandView":
            break;
        case "DrawMode":
            break;
        case "ClipPlaneCommand":
            break;
        case SView.Commands.CommandNames.CHANGEVIEWCOMMAND:
            break;
        case M3D.Utility.MessageType.Read:
            {
                break;
            }
        case M3D.Utility.MessageType.Scene:
            break;
        case M3D.Utility.MessageType.Loader:
            {
                break;
            }
        case M3D.Utility.MessageType.Shapes:
            {
                break;
            }
        case M3D.Utility.MessageType.Licence:
            {
                break;
            }
        case M3D.Utility.MessageType.Selector:
            {
                break;
            }
    }
}

    部分对外消息事件

class FunctionListener {
   static configLoaded(configType) {
   }
   static showHideAssemblyDilaog(isShow) {
   }
   static buttonClickFunction(id, enterMenu, returnMenu = MainBottomMenu) {
   }
   static changeBottomMenuState(event) {
   }
   static createSubMenu(id, enterMenu) {
   }
   static executeCommand(btnId) {
   }
   static showViewMenu(elementId) {
   }
   static selectWalkingMode() {
   }
   static showTopViewBar(isShow) {
   }
}
