I use gtk_pixmap_set() to change the pixmap.
The only awkward thing is getting the pixmap widget to change.

The toolbar returns the button when you add the toolbar item.
The button contains a vbox which has 2 children - the label and the pixmap
(assuming you are using standard toolbar buttons).
So you can do something like:


#ifdef GTK_HAVE_FEATURES_1_1_0
  vbox = GTK_BIN (toolbar_button)->child;
#else
  vbox = GTK_BUTTON (toolbar_button)->child;
#endif

  vbox_children = GTK_BOX (vbox)->children;

  /* Note that the label is added first in gtktoolbar.c which is why
     it is first in the list (unless you didn't set any label). */
  label = ((GtkBoxChild*)vbox_children->data)->widget;
  pixmap = ((GtkBoxChild*)vbox_children->next->data)->widget;

  gtk_pixmap_set (GTK_PIXMAP (pixmap), gdk_pixmap, mask);
