size_request/size_allocate question

[Jaap Karssenberg <j g karssenberg student utwente nl>]

Hello,

I try to subclass Gtk2::HBox and I want to handle size allocation 
myself. I figured overloading size_request() and size_allocation() would 
 do the trick, but these methods don't get called when the widget is 
shown :( I've included my code below, does anyone have a suggestion what 
I do wrong ?

Thanks,

        $self->SUPER::size_allocate($allocation);
}
