setting the vertical scroll bar position explicitly

[thomas joseph <thomascanny yahoo co nz>]

Hi All,

 I am new to GTK. I created a small GUI for my project
 which displays operational log messages of my
 device. 

  I created a text widget with a vertical scrollbar
and
  it's working fine. But I want one more feature,
  whenever a new message is added at the end  I want 
  the scrollbar to move down. (I always want to show 
  the latest messages.)

 Can somebody tell me what are the right set of APIs 
 for setting or moving the vertical scrollbar down 
 explicitly.

 I am looking at set_scroll_adjustment_signal and 
 gtk_adjustment_value_changed.

 Thanks in advance,

  --thomas
