Re: [gtkmm] getting the content of a Row in a Treeview

[Matthew Walton <matthew alledora co uk>]

Use the TreePath to build an iterator which points at the activated row.
Dereferencing the iterator will then obtain the Row object required. I
have code that looks something like this (rewritten to make sense
without all the class definitions and other stuff going on)

void WindowClass::on_treeview_row_activated(const Gtk::TreePath &path,
Gtk::TreeViewColumn *column) {
  Gtk::TreeModel::iterator iter =
treeview.get_model()->get_iter(const_cast<Gtk::TreePath&>(path));

  // *iter is then the activated Row
}

I know this is kind of messy, but I wrote the code I based that snippet
on a long time ago and haven't touched it for some time. It's possible
ti doesn't even work anymore, but it should be vaguely right.
