Get a Widget-Pointer

[Konrad Mader <konrad mader gmx de>]

Hi,

I define with glade 
a top_level_window, named 'Hauptfenster',
inside of 'Hauptfenster' a vbox named 'vbox2',
inside of 'vbox2 a alignment named 'alignment1',
inside 'alignment1' a clist named 'clist1'.

After a 'create_Hauptfenster()' I want to use 
gtk_clist_append(). How can I handle 'clist1'?

Thanks
Konrad Mader
