Re: Vertical Slider

[Giaslas Georgios <giaslas ceid upatras gr>]

if you don't need to display the value next to the slider 
you can simply create the slider with range from 0 to 72
and substract 60 at the callback
and call gtk_scale_set_draw_value () in order not to display the value
next to the slider
