2// Name: ScintillaWX.cxx
3// Purpose: A wxWidgets implementation of Scintilla. A class derived
4// from ScintillaBase that uses the "wx platform" defined in
5// PlatformWX.cxx 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.
