//    TParamUIConcept  definition
//***********************************************************************************************

//! Defines the User Interface Types available for a group of TParam objects.
/*!
  A User Interface Concept is used to associate parameters to the way they
should be
  interactively represented. For example, a TDoubleParamP may be used to
represent
  multiple objects, such as lengths or angles; a couple of TPointParamP may
represent
  vectors, and so on. Observe that each entry in the list is associated to a
specific
  struct of parameter objects.
\n\n
  The list in the Type enum provides all the interface types currently supported
by Toonz.
