It has been said before that, when using attributes to connect data from the model to a cell renderer property, the data in the model column specified in Gtk::TreeView#add_attributes must always be of the same type as the data type that the property requires.
-This is usually true, but there is an exception: if you add a text cell renderer's "text" property to a model column, the model column does not need to be a ((*String*)), it can also be one of several other classes, e.g. ((*TrueClass, Integer, FixNum,*)) or ((*Float.*)) The text cell renderer will automatically display the values of these types correctly in the tree view. For example:
