[Gtk-sharp-list] Treeviews and popups, and easy way?

[Anders Aagaard]

Using ConnectBefore is fine when you dont need the treeview.selection data to
be up to date.  When you need it to be up to date, you have to manually make
sure the selection is correct, by using GetPathAtPos with X,Y coordinates,
which gets especially fun when your dealing with multiple selections.  And
that's hackish imo.

Making the columns clickable isn't really a solution for me, my popupbox
shows a file tree of files that are hidden from view (it's a media manager,
text files/subtitles etc are not visible in the normal view).

I've ended up making my own custom treeview, which means my monodevelop
views isn't as pretty, but atleast it works :)
