A clean and organized approach to "transforming" Emacs in a
"component(TM)", should provide a similar codebase for both GNOME
and KDE. If the design is good, the GNOME/KDE specific code should be
"minimal".
Of-cource this is the way I see it. Could a Bonobo hacker confirm or
prove it false... ?

I could investigate it. But provided that I suffer from severe time
constraints this season, my report will not be in depth (for now).

The KTextEditor "Interface" (actually it is a namespace with lots of
interfaces), is located here:
http://developer.kde.org/documentation/library/3.0-api/classref/interfaces/KTextEditor.html
More specifically, KTextEditor::EditInterface
(which is the most important), is presented here (just to get an idea of what
it looks
like):
* EditInterface ()
* virtual ~EditInterface ()
* unsigned int editInterfaceNumber () const
* virtual QString text () const //the complete document as a single QString
* virtual QString text ( unsigned int startLine, unsigned int startCol,
unsigned int endLine, unsigned int endCol ) const
* virtual QString textLine ( unsigned int line ) const // All the text
from the requested line.
* virtual unsigned int numLines () const // The current number of lines in
the document
* virtual unsigned int length () const //the number of characters in the
document
* virtual int lineLength ( unsigned int line ) const //the number of
characters in the line (-1 if no line "line")
* virtual bool setText ( const QString &text )
* virtual bool clear () // clears the document
* virtual bool insertText ( unsigned int line, unsigned int col, const
QString &text )
* virtual bool removeText ( unsigned int startLine, unsigned int startCol,
unsigned int endLine, unsigned int endCol )
* virtual bool insertLine ( unsigned int line, const QString &text )
* virtual bool removeLine ( unsigned int line )
* virtual void textChanged ()
* virtual void charactersInteractivelyInserted (int ,int ,const QString&)
// not sure
Note that QString is a normal string class that can be
converted/constructed to/from a C string or a C++ std::string.
Also note that NOT all of the KTextEditor interfaces *should* be
implemented. For example the KTextEditor::ConfigInterface could be
ommited in favor of the emacs internal configuration system (I don't
know what it is called).
Please, tell me whether something is not clear or you need further
information on something.
Thank you,
Giannis
