What are you talking about?  You can pass any GObject-derived type as
the column type (not that it matters much, the net result is the same as
passing G_TYPE_OBJECT).  You get back the objects that you stored there.

If you store objects of different classes to the same column and want to
know the precise type use RTTI: type macros such as MY_IS_FOO(),
G_TYPE_FROM_INSTANCE(), g_type_is_a(), etc.
