The ATK interface implemented by valuators and components which display or select a value from a bounded range of values.
<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. <at-kvalues> may be
read-only, in which case attempts to alter the value return FALSE to indicate
failure.
<atk-value>) (value <gvalue>)Gets the value of this object.
- obj
- a GObject instance that implements AtkValueIface

- a
<gvalue>representing the current accessible value
<atk-value>) (value <gvalue>)Gets the maximum value of this object.

<atk-value>) (value <gvalue>)Gets the minimum value of this object.

- ‘
#t’ if new value is successfully set, ‘#f’ otherwise.
<atk-value>) (value <gvalue>)Gets the minimum increment by which the value of this object may be changed. If zero, the minimum increment is undefined, which may mean that it is limited only by the floating point precision of the platform.
