Idling&ExternalEvent 空闲事件与外部事件

空闲事件

空闲事件是指在revit无操作时执行命令TheBuildingCoder解释code 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😸

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:IexternalEventHandlercode public class ExternalHandler : IExternalEventHandler { public void Execute(UIApplication app) { ThisApplication.thisApp.AddIdlingEvent(app); } public string GetName() { return "ExternalHander.Excute()"; } }
