[pygtk] Text Hiding in gtk.TextView / TextBuffer

[Wildemar Wildenburger]

Hi :)

Is there an easy way to hide certain lines of a buffer in a TextView? 
That is, I would like to have a TextView that only displays certain 
lines of its buffer (most useful for "code folding" and "narrowing", 
among other things.). Any ideas or pointers?

I could imagine just using another buffer that only contains the portion 
of the buffer that is currently relevant, but then I would lose some MVC 
functionality (say, different views on the same file, but narrowed to 
different parts of the buffer wouldn't work). Maybe implementing an 
intermediate buffer that acts like a view on a buffer (in the SQL sense) 
is the best option, but that seems like a lot of work; I hope that there 
is an easier way.

Thanks for any hints.
