   2 // Name:        stc.cpp
   3 // Purpose:     A wxWindows implementation of Scintilla.  This class is the
   4 //              one meant to be used directly by wx applications.  It does not
   5 //              derive directly from the Scintilla classes, but instead
   6 //              delegates most things to the real Scintilla class.
   7 //              This allows the use of Scintilla without polluting the
   8 //              namespace with all the classes and identifiers from Scintilla.
