Re: Cast Gtk::TreeModel::iterator to int

[Milosz Derezynski <internalerror gmail com>]

A Gtk::TreeModel::Path is just a wrapper for a GtkTreePath which truly is just an array of ints. If you have a simple vector-like model then you can get a row number from the TreePath like Jose said it.

To get a row number from a path, use
Gtk::TreeModel::Path::get_indices().  It returns an array of the
components in the path, which can be stored in a standard container.

If the model is a ListStore, the first component of the path should be
the row number.  If it is a TreeStore, the first component is also a row
in the model, but the next component represents the location of a child
row with respect to the parent, and so on.
