HI
Yes i understood that.
Notepad++ IS open source
https://github.com/notepad-plus-plus/notepad-plus-plus
and also using scintilla

QScintilla is fine but do note that
"QScintilla is available under the GNU GPL v3 and under a commercial license."

Thanks for notice the license ... not good for me .
Is there any other Qt scintilla wrapper ?

what about performance if i use the Qt build in text features ?
i downloaded some open source editors which using Scintilla
and the performance are slow but then again maybe they have been programed wrong .
