The editor doesn't have any facility for hot spots now and there
isn't any point<->text position conversion in the API now so 
you'ld be stuck going through the API to call GTK and Scintilla
calls to get the point and convert it to position, etc.  If you 
have access to the Wing sources, there is related code in the 
src/edit/editor.py file (search for _from_point and point_).

It should probably throw and exception but you need this instead 
for it to work:

doc.DeleteChars(0, doc.GetLength()-1)

Yes, for now this is the way to do it (we designed the API to 
have one way to do things, rather than adding lots and lots of

Odd, it should say """ Delete characters in given range """ -- 
although I realize that's not terrible information rich either...
we'll try to improve this.

In any case, the goal is to do all the documentation in the
docstrings in the code and if anything is added to the manual 
as a reference, it would be auto-generated from those docstrings.
