ArcToolBox工具栏上添加自定义工具或命令

工具类：继承于BaseTool，若为命令，则继承于BaseCommand。

using ESRI.ArcGIS.ADF.BaseClasses;//该引用不同于AO9.2<br> using ESRI.ArcGIS.Carto;<br> using ESRI.ArcGIS.Controls;<br> using System.Windows.Forms;<br> using ESRI.ArcGIS.Geometry;<br> using ESRI.ArcGIS.Geodatabase;<br> using System;<br> using WorldMap;<br> public sealed class SearchData : BaseTool//若为命令，继承于BaseCommand<br> {<br> IMapControl3 mapControl;<br> private IHookHelper m_HookHelper = new HookHelperClass();<br> public SearchData()<br> {<br> //设置工具按钮的属性<br> base.m_caption = “Search Data”;<br> base.m_toolTip = “Search Data”;<br> base.m_message = “Search Data”;<br> base.m_name = “Search Data”;<br> base.m_cursor = Cursors.Help;<br> try<br> {<br> base.m_bitmap = new System.Drawing.Bitmap(Application.StartupPath + @”/icon/search3.bmp”);<br> }<br> catch<br> {<br> MessageBox.Show(this.Name+Environment.NewLine+”BitMap path is wrong!”);<br> }

}
public override void OnCreate(object hook)
{
m_HookHelper.Hook = hook;
if (hook is IToolbarControl)
{
IToolbarControl toolbarControl = (IToolbarControl) hook;
mapControl = (IMapControl3) toolbarControl.Buddy;
}
}
public override bool Enabled
{
get
{
if(m_HookHelper.FocusMap == null)
return false;
return true;
}
}
//在MapControl上的事件
public override void OnMouseDown(int Button, int Shift, int X, int Y)
{
//Identify功能
try
{
IPoint pPoint;
IFeatureLayer pFeatureLayer;
ISpatialFilter pSpatialFilter;
IFeatureSelection pFeatureSelection;
ICursor pCursor;
IFeature pFeature;
ISelectionSet pSelectionSet;
pPoint = this.mapControl.ToMapPoint(X, Y);
pFeatureLayer = (IFeatureLayer)this.mapControl.get_Layer(3);
pFeatureSelection = (IFeatureSelection)pFeatureLayer;
pSpatialFilter = new SpatialFilterClass();
pSpatialFilter.Geometry = (IGeometry)pPoint;
pSpatialFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;
this.mapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null);
pFeatureSelection.SelectFeatures(pSpatialFilter, esriSelectionResultEnum.esriSelectionResultNew, true);
this.mapControl.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection, null, null);
pSelectionSet = pFeatureSelection.SelectionSet;
pSelectionSet.Search(null, false, out pCursor);
pFeature = (IFeature)pCursor.NextRow();
if (pFeature != null)
{
IFields pFields = pFeatureLayer.FeatureClass.Fields;
DataForm dataForm = DataForm.NewForm();
dataForm.textBox1.Text = pFeature.get_Value(pFields.FindField(“中文名称”)).ToString();
dataForm.Show();
this.mapControl.FlashShape(pFeature.Shape, 3, 200, null);
}
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
}
 

工具或命令添加到ArcToolBar上：

axToolbarControl1.AddItem(new SearchData(), 0, -1, false, 0, esriCommandStyles.esriCommandStyleIconOnly); 

效果图：

ps:从自定义工具或命令中访问MapControl，可以先从hook得到ArcToolBar，进而通过buddy属性得到mapcontrol。
