#include <Mod/Mesh/Gui/Selection.h>

Detailed Description

Transport the changes of the Selection This class transports closer information what was changed in the selection. It's an optional information and not all commands set this information. If not set all observer of the selection assume a full change and update everything (e.g 3D view). This is not a very good idea if, e.g. only a small parameter has changed. Therefore one can use this class and make the update of the document much faster!
