Gtk+ styling questions

[Glus Xof <gtglus gmail com>]

Hi guys,

Trying to better understand the Gtk+ styling mechanism, I wrote the code: http://codepad.org/AgkL7oZ1

And I'd like to ask you:

Why if the label (Gtk::Label la_test) is named (ie. "TestStyle", as shown in lines 227, 317-327) does not reflect the style selections inside ???

Why I'm doing wrong??
