A Gtk::Scale is a slider control used to select a numeric value. To use it, you'll probably want to investigate the methods on its base class, Gtk::Range, in addition to the methods for Gtk::Scale itself. To set the value of a scale, you would normally use set_value(). To detect changes to the value, you would normally use signal_value_changed().
The Gtk::Scale widget is an abstract class, used only for deriving the subclasses Gtk::HScale and Gtk::VScale, so you should instantiate them instead.

| Set the number of decimal digits. This also causes the adjustment to be rounded off so the retrieved value matches the value the user sees. Setting digits to 1 gives for example 1.0, 2 gives 1.00, etc. |
