## Description

A widget that displays any object that implements the GtkTreeModel interface in an icon bar.

Example 1. Creating a new ExoIconBar with a GtkListStore

    enum
    {
      PIXBUF_COLUMN,
      STRING_COLUMN,
      N_COLUMNS,
    };

    {
      GtkListStore *store;
      GtkWidget    *bar;

      // make a new list store
      store = gtk_list_store_new (N_COLUMNS, GDK_TYPE_PIXBUF, G_TYPE_STRING);

      // fill the store with data
      fill_store (store);

      // create the icon bar
      bar = exo_icon_bar_new_with_model (GTK_TREE_MODEL (store));
      exo_icon_bar_set_pixbuf_column (EXO_ICON_BAR (bar), PIXBUF_COLUMN);
      exo_icon_bar_set_text_column (EXO_ICON_BAR (bar), TEXT_COLUMN);
      gtk_widget_show (bar);

      // the icon bar keeps a reference on the store now
      g_object_unref (G_OBJECT (store));

      // add the bar to your GUI now...
    }
