Oops, I wrote too fast : you're right, on the source side we create 
the site.

OK, thanks a lot for these explanations/warnings. I had a bad feeling 
about the way I was implementing these things...

I have one more question though : in fact what I've done is allowing 
extended selection on a ctree with drag&drop activated, so you don't 
have to use the shift key to select and move several rows (now that 
I've tried this behaviour, I really think it's very user-friendly 
and a must-have feature - at least it should be an option the user 
can choose, imho).
And I'm looking for a way to do that in the best possible way.

As you point out, I'd like to take into account user's settings, and 
use as most as I can gtk standard functions to achieve that goal, to 
be compatible with future versions, and not reinvent the wheel :-)
