hscale range adjustment

[paul thacker st com]

     Hello,
     
     I am developing an app which contains a window that has three hscales. 
     This window can be created/destroyed during program execution at the 
     direction of the user. I would like to update the upper, lower and 
     value variables of the associated Gtk_Adjustments whenever the window 
     is created, based on a global structure containing configuration 
     settings.
     
     Is there a function such as "set_range (scale, min, max, small_step, 
     page_step)" that makes this a simple operation? If not, is there an 
     easy way to do this?
     
     Thanks,
     Paul
