### Implementations

AtkValue is implemented by `AtkNoOpObject`.

### Detailed Description

`AtkValue` 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 `AtkObject` representations which implement `AtkValue` on the component's behalf. `AtKValues` may be read-only, in which case attempts to alter the value return FALSE to indicate failure.

### Structures
