+/// \class SMESHGUI_SelectionProxy
+/// \brief Provide operations over the selected object.
+///
+/// The selection proxy class is aimed to use in dialogs to access mesh object
+/// data either from actor or directly from CORBA reference, depending on what
+/// of them is accessible.
+/// This is useful in situations when some information is needed, but an actor
+/// was not created yet.
+///
+/// Selection proxy can be constructed in two ways:
+/// - From interactive object: this performs full proxy initialization including
+/// pick-up of an actor from the current viewer if it exists.
+/// - From mesh source object (CORBA reference); for performance reasons in this
+/// case full initialization is not immediately done and performed only when
+/// needed.
