atk.Value — the ATK interface implemented by valuators and components which display or select a value from a bounded range of values.

Synopsis

class atk.Value(gobject.GInterface):
    def get_current_value()
def get_maximum_value()
def get_minimum_value()
def set_current_value(value)

Description

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.
