Classes that implement IEditToolEvents

Classes	Description
EditToolEvents	Helper coclass for working with the outbound interface on noncreatable object classes in VB.

Remarks

These events are only broadcast if the user is moving the tool around the map with the left mouse button depressed.

[C#]

The following code block illustrates now to configure a client to access the edit tool's events, and reports the number of times each event is fired when moving the edit tool.

The code assumes you have a reference to the application. You will also need to reference ESRI.ArcGIS.SystemUI (for ICommand) in addition to the libraries implied within the code.

public void SetupEditToolEvents()
{
  //get the edit tool
  ESRI.ArcGIS.Editor.IEditTool editTool = m_application.Document.CommandBars.Find(
    "Editor_EditTool", true, true).Command as ESRI.ArcGIS.Editor.IEditTool;
  //hook up the events
  ((ESRI.ArcGIS.Editor.IEditToolEvents_Event)editTool.EventSource).OnBeginMove += new 
    ESRI.ArcGIS.Editor.IEditToolEvents_OnBeginMoveEventHandler(EditToolEvents_StartCmd_OnBeginMove);
  ((ESRI.ArcGIS.Editor.IEditToolEvents_Event)editTool.EventSource).OnMove += new 
    ESRI.ArcGIS.Editor.IEditToolEvents_OnMoveEventHandler(EditToolEvents_StartCmd_OnMove);
  ((ESRI.ArcGIS.Editor.IEditToolEvents_Event)editTool.EventSource).OnFinishMove += new  
    ESRI.ArcGIS.Editor.IEditToolEvents_OnFinishMoveEventHandler(EditToolEvents_StartCmd_OnFinishMove);      
}
void EditToolEvents_StartCmd_OnMove(ESRI.ArcGIS.Geometry.IPoint loc)
{
  i += 1;
}
void EditToolEvents_StartCmd_OnFinishMove(ESRI.ArcGIS.Geometry.IPoint loc)
{
  j += 1;
  System.Windows.Forms.MessageBox.Show(string.Format("OnBeginMove fired: {0}, OnMove fired: {1}, OnFinishMove fired: {2}",k,i,j));
}
void EditToolEvents_StartCmd_OnBeginMove(ESRI.ArcGIS.Geometry.IPoint loc)
{      
  //reset counter
  i = 0;
  j = 0;
  k = 0;
  //start counting 
  k += 1;
}
int i, j, k = 0;
