Sliders

A slider allows the user to quickly select a value from a fixed, ordered range, or to increase or decrease the current value. The control looks like the type of slider that you might find on an audio mixing desk or a hi-fi's graphic equalizer. In gtk, you implement a slider using the GtkHScale or GtkVScale controls, for horizontal or vertical sliders respectively.
