[转] ArcGIS engine中气泡标注的添加、修改

　　你微微地笑着，不同我说什么话。而我觉得，为了这个，我已等待得久了。

　　　　 ——泰戈尔

　　喜欢看你微微的笑着，哪怕你一句话都不说，看见你笑，仿佛四季如春……笑，蕴含着着一种信任，一种安全，一种爱护，一种宽容，一种心灵的感应……宝贝，朝我笑笑，好么？

　　生活本已是一杯苦酒，我们何不笑着饮下？一颗感恩的心，一颗热爱生活的心，爱惜那些值得爱的人，一起欢乐，一起将各自生活的苦酒淡化，每天都让我们灿烂的笑……

　　不要认为后面还有更好的，因为现在拥有的就是最好的。不要因为距离太远而放弃，爱情可以和你一起坐火车的。不要因为对方不富裕而放弃，只要不是无能的人，勤劳可以让你们富裕的。不要因为父母反对而放弃，你会发现因为这个原因而反放弃的爱情，将是你一生的悔恨。其实对于爱情，越单纯越幸福。一生只谈一次恋爱是最好的，经历的太多了，会麻木；分离多了，会习惯；换恋人多了，会比较；到最后，你不会再相信爱情；你会自暴自弃；你会行尸走肉；你会与你不爱的人结婚，就这样过一辈子。

　　ArcGIS engine中气泡标注，是我们在编辑图形中一个重要的工具，能提供注释功能，下面的介绍怎么来编程实现callout的添加，以及怎么去修改它们！

 //  在Mapcontrol的mouseDown中添加下列内容，来添加气泡注释功能：callout.

 private void axMapControl1_OnMouseDown(object sender, IMapControlEvents2_OnMouseDownEvent e)

        {

                    axMapControl1.CurrentTool = null;

                    IPoint pPoint ;

                    pPoint = new PointClass();

                    pPoint.PutCoords(e.mapX, e.mapY);

                    IFormattedTextSymbol pTextSymbol = new TextSymbolClass();

                    pTextSymbol.Background = CreateBalloonCallout(e.mapX, e.mapY) as ITextBackground;

                    pTextSymbol.Direction = esriTextDirection.esriTDAngle;

                    pTextSymbol.Angle = 15;

                    ITextElement pTextElement = new TextElementClass();

                    pTextElement.Symbol = pTextSymbol as ITextSymbol;

                    pTextElement.Text = "MaDeSheng";

                    IElement ptexte = pTextElement as IElement;

                    pPoint = new PointClass();

                    pPoint.PutCoords(e.mapX * 0.90, e.mapY *1.1);

                    ptexte.Geometry = pPoint as IGeometry;

                    IMap pMap = axMapControl1.Map;

                    IGraphicsContainer pGraphicsContainer = pMap as IGraphicsContainer;

                    pGraphicsContainer.AddElement(pTextElement as IElement, 0);

                    this.axMapControl1.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);

}

红颜色的部分是产生气泡背景，具体程序如下：

public IBalloonCallout CreateBalloonCallout(double x, double y)

        {

            IRgbColor pRgbClr = new RgbColorClass();

            pRgbClr.Red = 225;

            pRgbClr.Blue = 225;

            pRgbClr.Green = 225;

            ISimpleFillSymbol pSmplFill = new SimpleFillSymbolClass();

            pSmplFill.Color = pRgbClr;

            pSmplFill.Style = esriSimpleFillStyle.esriSFSSolid;

            IBalloonCallout pBllnCallout = new BalloonCalloutClass();

            //pBllnCallout.Style = esriBalloonCalloutStyle.esriBCSRectangle;

            pBllnCallout.Style = esriBalloonCalloutStyle.esriBCSRoundedRectangle;

            pBllnCallout.Symbol = pSmplFill;

            pBllnCallout.LeaderTolerance = 5;

            IPoint pPoint = new ESRI.ArcGIS.Geometry.PointClass();

            pPoint.X = x;

            pPoint.Y = y;

            pBllnCallout.AnchorPoint = pPoint;

            return pBllnCallout;

        }

那么添加了之后如何修改呢?

双击事件！

private void axMapControl1_OnDoubleClick(object sender, IMapControlEvents2_OnDoubleClickEvent e)

        {

            if(e.button ==1)

            {

                //标注的修改

                if (((axMapControl1.CurrentTool) as ICommand).Name == "ControlToolsGraphicElement_SelectTool")//这一句的判断很牛B，我当时考虑了半天才搞出来。难点呀！toolbarControl中要加载esriControls.ControlsSelectTool工具

                {

                    IPoint pPoint = new PointClass();

                    pPoint.PutCoords(e.mapX, e.mapY);

                    IMap pMap = axMapControl1.Map;

                    IGraphicsContainer pGraphicsContainer = pMap as IGraphicsContainer;

                    IEnumElement pEnumElement = pGraphicsContainer.LocateElements(pPoint, 10);

                    if (pEnumElement != null)

                    {

                        IElement pElement = pEnumElement.Next();

                        if (pElement is ITextElement)

                        {

                            ITextElement ptextElement = pElement as ITextElement;

                            labelEditCallout pLabelEditCallout = new labelEditCallout(ptextElement.Text, ptextElement.Symbol);

                            pLabelEditCallout.ShowDialog();

                            ptextElement.Text = pLabelEditCallout.inputText;

                            ptextElement.Symbol = pLabelEditCallout.textSymbol;

                            pGraphicsContainer.DeleteElement(pElement);

                            pGraphicsContainer.AddElement(pElement,0);

                         //这两句可以用pGraphicsContainer.UpdataElement(pElement);来代替

                            this.axMapControl1.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);

                        }

                    }

                }

            }

        }

labelEditCallout是我自己弄的一个修改样式，其实很简单的一个页面，截图如下：
