伟景行Citymaker管廊三维Gis实现鼠标点选功能

在Citymaker三维Gis平台上用C#实现点选功能

效果如下(技术交流可加群：161154103)

首先设置鼠标为点击选择状态，代码如下：

 this.axRenderControl.MouseSelectMode = gviMouseSelectMode.gviMouseSelectClick;

 this.axRenderControl.MouseSelectObjectMask = gviMouseSelectObjectMask.gviSelectAll; 

设置三维Gis上鼠标点击监听事件

this.axRenderControl.RcMouseClickSelect +=new CityMaker.Controls._IRenderControlEvents_RcMouseClickSelectEventHandler(axRenderControl_RcMouseClickSelect);

具体的鼠标事件函数：

 publicvoid axRenderControl_RcMouseClickSelect(objectsender,_IRenderControlEvents_RcMouseClickSelectEvent e)

 {

       if(e.pickResult ==null)

          return;

       IFeatureLayerPickResultlayerresault = e.pickResultas IFeatureLayerPickResult;

       if(layerresault !=null)

       {

            //高亮选中的要素

            layerresault.FeatureLayer.HighlightFeature(layerresault.FeatureId, 0xffff0000);

            //利用ITableLabel进行展示

            ITableLabeltableLabel =this.axRenderControl.ObjectManager.CreateTableLabel(7, 2,Guid.Empty);

            tableLabel.VisibleMask =gviViewportMask.gviViewNone;

            tableLabel.Position = pos;

            tableLabel.SetColumnWidth(0, 80);

            tableLabel.TitleText ="烟感器：详细信息";

            tableLabel.SetRecord(0, 0,"链接状态");

            tableLabel.SetRecord(0, 1,"良    好");

            tableLabel.SetRecord(1, 0,"所属分区");

            tableLabel.SetRecord(1, 1,"1#防火分区");

            tableLabel.SetRecord(2, 0,"所属仓位");

            tableLabel.SetRecord(2, 1,"第二仓");

            tableLabel.SetRecord(3, 0,"所属位置");

            tableLabel.SetRecord(3, 1,"第三支线8米");

            tableLabel.SetRecord(4, 0,"重量");

            tableLabel.SetRecord(4, 1,"120g");

            tableLabel.SetRecord(5, 0,"保护级别");

            tableLabel.SetRecord(6, 1,"IP23");

            tableLabel.SetRecord(6, 0,"执行标准");

            tableLabel.SetRecord(6, 1,"GB 4715—2005");

            tableLabel.TitleBackgroundColor = 0xffffffff;

           TextAttribute capitalTextAttribute = new TextAttribute();

            capitalTextAttribute.TextColor = 0xff000000;

            capitalTextAttribute.Font ="宋体";

            capitalTextAttribute.TextSize = 14;

            capitalTextAttribute.MultilineJustification =gviMultilineJustification.gviMultilineLeft;

           //capitalTextAttribute.Bold = true;

            tableLabel.TitleTextAttribute = capitalTextAttribute;

            tableLabel.TableBackgroundColor = 0xd0000000;

           TextAttribute TextAttribute = new TextAttribute();

            TextAttribute.TextColor = 0xffffffff;

            TextAttribute.Font ="宋体";

            TextAttribute.TextSize = 12;

            TextAttribute.MultilineJustification =gviMultilineJustification.gviMultilineLeft;

           //TextAttribute.Bold = true;

            tableLabel.SetColumnTextAttribute(0, TextAttribute);

            tableLabel.VisibleMask =gviViewportMask.gviViewAllNormalView;

       }

}
