I assume the "GtkTreePath *path" is the row where double click happened. You can easily determine if it's a top node or not in your callback function, just do nothing if it is. From the on-line reference:
"A path is essentially a potential node. It is a location on a model that may or may not actually correspond to a node on a specific model. The GtkTreePath struct can be converted into either an array of unsigned integers or a string. The string form is a list of numbers separated by a colon. Each number refers to the offset at that level. Thus, the path “0” refers to the root node and the path “2:4” refers to the fifth child of the third node." Use http://developer.gnome.org/gtk/2.24/GtkTreeModel.html#gtk-tree-path-to-string to convert a path to a string. Or, you can use http://developer.gnome.org/gtk/2.24/GtkTreeModel.html#gtk-tree-model-get-iter-first to get the iter for top node and compare with the double clicked iter to see if it's the same one.
