2007-06-10 Emmanuele Bassi <ebassi@gnome.org>
* gtk/gtkscalebutton.[ch]: Fix some coding style bits.
(gtk_scale_button_dispose), (gtk_scale_button_class_init),
(gtk_scale_button_init): Use the GObject private data API instead
of allocating the private structure ourselves.
(gtk_scale_button_dispose), (gtk_scale_button_finalize): Free
the icons string vector inside ::finalize and not in ::dispose.
(gtk_scale_button_update_icon): Use g_strv_length() instead
of an empty for loop.
