   2 // Name:        ScintillaWX.h
   3 // Purpose:     A wxWidgets implementation of Scintilla.  A class derived
   4 //              from ScintillaBase that uses the "wx platform" defined in
   5 //              PlatWX.cpp.  This class is one end of a bridge between
   6 //              the wx world and the Scintilla world.  It needs a peer
   7 //              object of type wxStyledTextCtrl to function.
