The ATK interface implemented by valuators and components which display or select a value from a bounded range of values.
This 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::Values may be read-only, in which case attempts to alter the value return false to indicate failure.

value | A Value representing the current accessible value. |
void Atk::Value::get_maximum_value | ( | Glib::ValueBase & | value | ) | const |

value | A Value representing the maximum accessible value. |
void Atk::Value::get_minimum_value | ( | Glib::ValueBase & | value | ) | const |

value | A Value representing the minimum accessible value. |
bool Atk::Value::set_current_value | ( | const Glib::ValueBase & | value | ) |

if new value is successfully set, false
otherwise.
