Use the delegate GtkTreeSelection object...
(make sure your view is configured to allow multiple selections)

Same as above... use the tree selection apis...

In the api reference:

There are not really any items in the treeview, the treeview
is a widget that renders the data that is in your GtkTreeModel
implementation (or usually you are using a standard GtkListStore
or GtkTreeStore).

A GtkBox is not a GtkFixed... unless you are writing some kind of
embedded kiosk like application that runs at a fixed resolution; you
probably dont want to use GtkFixed at all (i.e.: your interface will
resize properly and be usable on a variety of desktops if you
avoid using the special case GtkFixed widget).
