OK, so I set everything in order to have an Alignment as the first and sole 
child of the Tree_item , and then a label as a child of the Alignment.

The problem now is that I can't get the child of the Alignment using method 
#children; Alignment is recognized to be a GObj.widget and so I can't use 
method #children. How can I tell Lablgtk that Alignment is a single-child 
Container, and that I need the child?

I'm completely stuck, is it because I'm starting GTK from the ocaml side?
Is there any book that you could suggest to me, apart from the super-heavy GTK 
tutorial and the not-so-commented GTK API?
