## Events

- [ActiveDocumentChanged](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/activedocumentchanged.md): (static) This event is raised when the active document used by modeless user interface changes. On Mac Rhino this will get raised before the [RhinoDoc.NewDocument](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/newdocument.md), [RhinoDoc.BeginOpenDocument](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/beginopendocument.md) and [RhinoDoc.EndOpenDocument](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/endopendocument.md) events. Mac Rhino will also raise this event with 0 for the document Id and a null document pointer when the last document is closed. Windows Rhino will raise this event after the [RhinoDoc.NewDocument](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/newdocument.md), [RhinoDoc.BeginOpenDocument](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/beginopendocument.md) and [RhinoDoc.EndOpenDocument](https://developer.rhino3d.com/api/rhinocommon/type/rhino.rhinodoc/endopendocument.md) events when a new or existing model is opened.
