GtkHScrollbar Constructor
A scrollbar needs a GtkAdjustment in order to
operate. The values that you give to the adjustment object will depend
on the situation where the scrollbar is intended to be used.
All scrollable widgets have their own adjustment object(s), and in most
instances where you are most likely to need a horizontal scrollbar it is
possible to create a handle for the widget's horizontal
GtkAdjustment and assign that as the new
scrollbar's adjustment object.
There is no working horizontal adjustment object in
GtkText.
