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. | |
