Hi,
   In the future you should try to direct your question to a more specific list,
usually you will get faster results that way.

I can see that it might have been hard to guess which one for this question
(gtk-app-devel-list or gtk-list is the right place for glib/gobject
related questions).

The implementations of 'GType foo_bar_get_type (void)' are defined
by the G_DEFINE_TYPE() macro family (you will see in glade-text-button.c
a line that starts with G_DEFINE_TYPE_WITH_CODE (... ))

The GObject docs have some code fragments explaining the boiler plate
code needed to write objects using the gobject type system:
