IEngineEditor与IWorkspaceEdit，以及相关的事件监听

IEngineEditor适用于直接在图层上的编辑，例如使用“要素编辑”工具菜单上的“开始编辑”等工具进行编辑，相应的事件使用IWorkspaceEdit监听，例如以下的代码：

 private IEngineEditor m_EngineEditor = new EngineEditorClass();
 private IEngineEditEvents_Event m_EngineEditEvents ;
 private void MainForm_Load(object sender,EventArgs e)
 {
      //get the MapControl
      m_mapControl = (IMapControl3)axMapControl1.Object;
      //disable the Save menu (since there is no document yet)
      menuSaveDoc.Enabled = false;
      m_EngineEditEvents = (IEngineEditEvents_Event)m_EngineEditor;
      m_EngineEditEvents.OnStartEditing += new IEngineEditEvents_OnStartEditingEventHandler(m_EngineEditEvents_OnStartEditing);
 }
 void m_EngineEditEvents_OnStartEditing()
 {
      MessageBox.Show("Start Editing");
 }

 

IWorkspaceEdit适用于直接对workspace进行的编辑，相应的事件使用IWorkspaceEditEvents_Event监听，例如以下的代码：

 private IWorkspaceEdit wsEdit;
 private IWorkspaceEditEvents_Event wsEditEvents;
 private void MainForm_Load(object sender,EventArgs e)
 {
       //get the MapControl
       m_mapControl = (IMapControl3)axMapControl1.Object;
       //disable the Save menu (since there is no document yet)
        menuSaveDoc.Enabled = false;
       wsEdit = MyTool.GetWorkspaceEdit(map1.Map);
       wsEditEvents = (IWorkspaceEditEvents_Event)wsEdit;
       wsEditEvents.OnStopEditing += new IWorkspaceEditEvents_OnStopEditingEventHandler(wsEditEvents_OnStopEditing);
 }
 void wsEditEvents_OnStopEditing(bool saveEdits)
 {
       MessageBox.Show("StopEditing");
 }
