the base class of all shapes has an empty implementation http://opengrok.adfinis-sygroup.org/source/xref/aoo-trunk/main/svx/source/unodraw/unoshape.cxx#2054 you'll find this in several places, for example https://issues.apache.org/ooo/show_bug.cgi?id=121263 I'm not sure if this is for performance issues, or simply a bug. I'm not aware of this being reported, so please open a new bug, this will help improve the API. > So is there exists workaround? add an old css::document::XEventListener at the document model, you'll get notified of ShapeModified event, EventObject.Source is the shape; something like the attached source.
