atk.Value — the ATK interface implemented by valuators and components which display or select a value from a bounded range of values.
| class atk.Value(gobject.GInterface): | 
atk.Value should
    be implemented for components which either display a value from a
    bounded range, or which allow the user to specify a value from a bounded
    range, or both.  For instance, most sliders and range controls, as well
    as dials, should have atk.Object
    representations which implement atk.Value on the
    component's behalf.  atk.Value objects
    may be read-only, in which case attempts to alter the value return
    False to indicate failure.
