Initial version of wxStyledTextCtrl, a Scintilla wrapper. There is
still LOTS and LOTS to be done, but this is already very functional. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@6555 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

// Name: ScintillaWX.cxx
|
||||
// Purpose: A wxWindows implementation of Scintilla. A class derived
|
||||
// from ScintillaBase that uses the "wx platform" defined in
|
||||
// PlatformWX.cxx This class is one end of a bridge between
|
||||
// the wx world and the Scintilla world. It needs a peer
|
||||
// object of type wxStyledTextCtrl to function.
