Need some help with vscale ;-(
 

I am a new Linux user and now facing the problem about vscale widget..
1. The maximum value is in the above but the minimum value is in the bottom, anyway to fix that..
2. What function should be called to receive the initial value, get the value changed from slider. Is it needed to be in different function or can use in same function..

Oh!! I am using Glade to implement the interface..
