Really,  Gtk::Fixed dont receive configure_events, as major of widgets do.
As i could  research (and Paul said, and i've tested) only Gtk::WIndow
(and maybe gtk::drawingarea) receives configure_events.
But as Albuquerque said, in the Gdk level, all gdkwindows receives the
configure_events (at last in its what the reference says). Dont know
why its not throwed to the gtk layer.
But, the most important, widgets resizes can be correctly tracked in
the on_size_allocate events, and i think its the correct way. My
problem with that event was that in the first interactions i was not
able to correctly manipulate GC's and do my job. Problem was solved
when i tracked the widget state correctly before operate.

Thanks to Paul, Albuquerque and you.
