Sorry, I think my instructions are rather misleading. The 
BaseTextEditorWidget is only meant to be used with a BaseTextDocument. 
You should probably not use its setTextDocument function at all, which 
only happens to be available because it's a subclass of the 
QPlainTextEdit widget.

If you need to integrate a class that derives from QTextDocument, you 
should probably look into changing your own class to derive from the 
BaseTextDocument instead.
