[Gtk-sharp-list] Directory/file-tree listing widget

[Tomek Lorek]

Hi there,
I'd like to use a widget that would have the functionality of the
directory/file/whatever-else tree, like this:
http://www.whereisit-soft.com/snap1.gif (the one at the left). I'd
like it to be filled with custom data rather than directories or files
from specified location. Is there any widget in gtk# that would do sth
like that? Is extending the TreeView with TreeStore model a good idea
or maybe there is sth closer to what I want?

Best regards,
tom
