/*
 * This file implements a "main" toolbar for Ethereal (suitable for gtk1 and
 * gtk2).
 *
 * As it is desirable to have the same toolbar implementation for gtk1 and gtk2 
 * in Ethereal, only those library calls available in the gtk1 libraries 
 * are used inside this file.
 *
 * Hint: gtk2 in comparison to gtk1 has a better way to handle with "common"
 * icons; gtk2 calls this kind of icons "stock-icons"
 * (stock-icons including: icons for "open", "save", "print", ...).
 * The gtk2 version of this code uses them.
