public static void IdlingHandler(object sender, Autodesk.Revit.UI.Events.IdlingEventArgs args)
        {
            UIApplication uiapp = sender as UIApplication;
            if (uiapp != null)
            {
                Autodesk.Revit.UI.UIDocument uidoc = uiapp.ActiveUIDocument;
                Autodesk.Revit.DB.Document doc = uidoc.Document;
                if (uidoc != null && doc != null)
                {
                    Reference re = uidoc.Selection.PickObject(Autodesk.Revit.UI.Selection.ObjectType.Element, "");
                    Element e = doc.GetElement(re);
                    
                    UserControl1.mainPage.Label1.Content = e.Id.ToString() + "\r";
                    uiapp.Idling -= IdlingHandler;
                }
            }
            else
            {
                System.Windows.Forms.MessageBox.Show("Must should Idling!");
            }
        }
  • TIPS:在挂载事件后最好后缀卸载事件，不然事件不会停止将一直重复idling里面的操作:smile_cat:

外部事件

  • 外部事件是指在窗体或外部调用revit命令时使用的事件
  • 需要引用接口:IexternalEventHandler
