a GtkHScale "is a" GtkRange. maybe you need to learn more about object orientation? check out the object hierarchy: GObject +----GtkObject +----GtkWidget +----GtkRange +----GtkScale +----GtkHScale GtkHScale is subclassed from GtkScale, which is subclassed from GtkRange, which is subclassed from... blah blah blah. That means you can treat a valid GtkHScale* as a valid GtkRange*. GtkWidget* p = gtk_hscale_new_with_range (0, 100, 1); gtk_widget_show( p ); printf("%f\n", gtk_range_get_value(GTK_RANGE(p)) ); as for getting the pointer to GtkHScale, look for information about lookup_widget(). you should see it used in Glade tutorials. - Ben _______________________________________________ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
