ArcGIS AddIn开发之：属性刷工具
来源：互联网 发布：usb3.0端口 编辑：程序博客网 时间：2024/05/01 14:38
利用AddIn开发，实现类似PS中仿制图章的工具。即通过鼠标点选的方式，选择一个要素作为源，然后将属性赋值给其他要素。
Tool代码：

} else { MessageBox.Show(pTmpFt.Fields.get_Field(i).Name + "字段所输入的值 类型不正确"); return; } } } //刷完属性闪烁要素 //FlashShape(pTmpFt); //保存交由编辑器执行 //pTmpFt.Store(); IFeatureSelection pFtSelection = (IFeatureSelection)((IFeatureLayer)pMap.get_Layer(AttributeBrushTool_SetPanel.cpidLyrId)); pFtSelection.Clear(); pFtSelection.Add(pTmpFt); pAv.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null); System.Threading.Thread.Sleep(100); pFtSelection.Clear(); System.Threading.Thread.Sleep(100); pAv.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null); System.Threading.Thread.Sleep(100); pFtSelection.Add(pTmpFt); pAv.PartialRefresh(esriViewDrawPhase.esriViewGeography, null, null); } } else { return; } } catch (System.Exception ex) { MessageBox.Show("发生未知异常_"+ex.Message); return; } } /// <summary> /// 要素闪烁 /// </summary> /// <param name="pTmpFt"></param> private void FlashShape(IFeature pTmpFt) { switch (pTmpFt.Shape.GeometryType) { case esriGeometryType.esriGeometryPoint: case esriGeometryType.esriGeometryPolygon: case esriGeometryType.esriGeometryPolyline: break;
