multiple toolbars with libgnomeuimm

[Mirek Kopriva <mkopriva hdsnet hu>]

Hi folks,
I'm trying to set multiple toolbars using libgnomeuimm.
The create_toolbar <cid:part1.04080101.00050805@hdsnet.hu> (const 
<file:///usr/share/doc/libgtkmm-2.4-doc/reference/html/classconst.html> 
Items::Array <cid:part2.07020305.07070609@hdsnet.hu>< Items::Info 
<cid:part3.04050609.02020606@hdsnet.hu> > &info) of
Gnome::UI:App class creates only one.
I was trying to use
add_toolbar <cid:part4.04020408.03000902@hdsnet.hu> (Gtk::Toolbar 
<cid:part5.00090006.08050406@hdsnet.hu> &toolbar,
                     const 
<file:///usr/share/doc/libgtkmm-2.4-doc/reference/html/classconst.html> 
Glib::ustring <cid:part6.07010103.04070400@hdsnet.hu> &name,        
                     BonoboDockItemBehavior behavior,
                     BonoboDockPlacement placement, int band_num, int 
band_position, int offset),

but without any sucess. Is there any other way? What about the Bonobo... 
parameters,
what are they for? I couln't find any docs about how to use this method.
Thanks a lot for answers.
