If you know the type at runtime then you can call the appropriate
version of this method, using an if/elseif/else or switch block, such as

int val = 0;
get_value(0, val);

or

Glib::ustring val;
get_value(0, val);

You could instead use the generic Glib::Value type, with the
not-really-public-API Model:get_value_impl(), but you would still need
the if/else/etc block to get an actual type out of that Glib::Value.
