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.
