[gnome-db] Question about gdaui-demo-5.0, how to extract just one demo and use it?

Having compiled the whole libgda suite the demo code in gdaui-demo-5.0
looks interesting.

What extra code is needed in addition to the source code that is shown
in the Source tab?  In the Source tab for the read-write grid for
example there's just a single function called do_grid_rw().  What
'outside' code is needed in addition?
