Because that's the signature that's needed by the get_widget_derived()
template.

As described here
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch19s03.html
cobject is something that you need to provide to the base constructor.
It's annoying that you need to do that, but you do.

refGlade should be used to get_widget() or get_widget_derived() the child
widgets. You almost always need to access some child widgets if you are
using a derived container with libglade.

The constructor is called when you call get_widget_derived().
