I had a look at the C documentation and I think that, yes, it uses the
GType to tell what data the entry should hold (see the description of
GdauiDataEntry [1]).  There is also a convenience function in the C API
that might not be readily obvious to create entries [2].  That function
is wrapped in libgda-uimm as
Gnome::GdaUI::DataEntry::create_data_entry() [3].
