The GTK.HScale widget is used to allow the user to select a value
using a horizontal slider. A GTK.Adjustment is used to set the
initial value, the lower and upper bounds, and the step and page
increments.
See W(Scale) for details
The position to show the current value, and the number of decimal
places shown can be set using the parent W(Scale) class's
functions.
