Re: Using VScales widgets

["rahul karurkar" <rahulkr mahindrabt com>]

Hi
you can give signal to the adjustment of VScale that "value-changed" and in
this callback you will update the other widget
if the other widget is scale then you write

the following function for the adjustment of the second VScale.
gtk_adjustment_set_value(GTK_ADJUSTMENT(adj2),float updationValue);
