這次我們完成的功能為拖動一個外部的UI物件到球球上：

  private void Button_PreviewMouseMove(object sender, MouseEventArgs e)
        {
            if(e.LeftButton== MouseButtonState.Pressed)
            DragDrop.DoDragDrop((Button)sender, sender, DragDropEffects.Move);
        }

  private void Gis3d_PreviewDrop(object sender, DragEventArgs e)
        {
            if (e.Data.GetData(typeof(Button)) != null)
            {
                MTGIS3D Pareant = ((MTGIS3D)IniRead.IniReadWrite.MPareant);
                GisLib.GIS2D.UserCanvas y1 = new GisLib.GIS2D.UserCanvas();

                Point3D va = ((MTGIS3D)IniRead.IniReadWrite.MPareant).GetJWForMouse(e.GetPosition(Pareant));

                Button Data = (Button)e.Data.GetData(typeof(Button));


                Button Y1 = new Button();
                Y1.Content=Data.Content;
                Y1.Width = Data.Width;
                Y1.Height = Data.Height;



                NewGisBiao.M3D.UserGisUI3dObject2 JuLiSechBiao = new NewGisBiao.M3D.UserGisUI3dObject2(); //新建一個承載UI物件的東東
                JuLiSechBiao.PareantEarth = (NewGisBiao.Base.GISInterfaseForBiao)IniRead.IniReadWrite.MPareant;//設定它的GIS球物件
                JuLiSechBiao.Manage = IniRead.IniReadWrite.BiaoManage;//設定它的標號管理器

                JuLiSechBiao.MaxZoom = 9;//最大顯示層，當小於9層的時候不顯示

                JuLiSechBiao.MUIValue = Y1;//UI物件

                JuLiSechBiao.DHi = 0.01;//相對於地形的高度
                JuLiSechBiao.ZScal = 0.6;//相對縮放
                JuLiSechBiao.Scal.ScaleX = 1; //固定東東
                JuLiSechBiao.Scal.ScaleY = 1;
                JuLiSechBiao.Scal.ScaleZ = 1;

                JuLiSechBiao.AutoScal = true;//是否自動縮放，不管在哪一層都是一樣大
                JuLiSechBiao.AutoAngle = true;//是否自動角度，使終對著攝像機
                JuLiSechBiao.CenterType = JunBiao.CenteType.左下角;//中心點型別
                IniRead.IniReadWrite.BiaoManage.AddJunBiao(JuLiSechBiao);//增加到軍標管理物件中。也可以不加
                JuLiSechBiao.MWidth = Data.Width;//三維面片的大小
                JuLiSechBiao.MHeight = Data.Height;
                JuLiSechBiao.MRX = 90;
                if (IniRead.IniReadWrite.MPareant is MTGIS3D) //手動重新整理一下自動角度。。。bug
                {
                    ((MTGIS3D)IniRead.IniReadWrite.MPareant).TextAxisAngleX.Angle += 0.001;
                    ((MTGIS3D)IniRead.IniReadWrite.MPareant).TextAxisAngleX.Angle -= 0.001;
                }


                JuLiSechBiao.Center = new Point(va.X, va.Y);//設定中心點

                JuLiSechBiao.ISShow = true;//顯示

            }
        }
 

效果 如下：
