That works but the user will still be able to select the row using the keyboard.

Check out TreeSelection.SelectFunction. You can write a handler that returns true if the row is allowed to be selected, false otherwise.

You could try catching the button-press event. Translate the events
X/Y to get the path to the selected row
(gtk_tree_view_get_path_at_pos). Then look up the data in the row to
see if you wish to disable it. If so, make sure the events RetVal is
true to stop further signal emission (thus stopping the treeview's
internal handler from receiving the event).
