But this still requires knowing the associated GtkRange pointer.  As I
mentioned previously I don't know what this is since glade is creating
the Scalebar directly from the output of gtk_adjustment_new().  It seems
like there should be a function that given a scalebar widget it returns
a pointer to the GtkRange or GtkAdjustment that is associated with it.
