AccessibleValue InterfaceAccessibleValue Interface — An interface implemented by valuators, sliders, and other onscren components which allow discrete or continuous values to be manipulated. |

The Value interface is exposed by sliders, scrollbars, dials, and other components which are used to change scalar values in an application. The interface may be used to change a value in an "approximately continuous" fashion, or in integer increments - the interface allows the client to determine the incremental granularity of the adjustments possible, the possible range of values, and the current value. It also allows the value to be programmatically set, if the implementor's state does not include READONLY.
void
AccessibleValue_ref (AccessibleValue *obj
);
Increment the reference count for an AccessibleValue object.
void
AccessibleValue_unref (AccessibleValue *obj
);
Decrement the reference count for an AccessibleValue object.
double
AccessibleValue_getCurrentValue (AccessibleValue *obj
);
Get the current value for an AccessibleValue.
double
AccessibleValue_getMaximumValue (AccessibleValue *obj
);
Get the maximum allowed value for an AccessibleValue.
double
AccessibleValue_getMinimumValue (AccessibleValue *obj
);
Get the minimum allowed value for an AccessibleValue.
SPIBoolean AccessibleValue_setCurrentValue (AccessibleValue *obj
,double newValue
);
Set the current value of an AccessibleValue.
