RD		 1////////////////////////////////////////////////////////////////////////////
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.
9//
10// Author: Robin Dunn
