fix memory leak as Dimitri suggested
[wxWidgets.git] / contrib / src / stc / stc.h.in
1 ////////////////////////////////////////////////////////////////////////////
2 // Name: stc.h
3 // Purpose: A wxWindows 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, and in fact there
6 // is no mention of Scintilla classes at all in this header.
7 // This class delegates all method calls and events to the
8 // Scintilla objects and so forth. This allows the use of
9 // Scintilla without polluting the namespace with all the
10 // classes and itentifiers from Scintilla.
