linking fix for wxUSE_VALIDATORS==0
[wxWidgets.git] / src / stc / stc.cpp.in
1 ////////////////////////////////////////////////////////////////////////////
2 // Name: stc.cpp
3 // Purpose: A wxWidgets 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 //
