{DISPLAYTITLE:XAccessibleValue}} In a typical GUI, there are many controls whose characteristic feature can be represented by a single numerical value. Examples are spin boxes, scales and sliders, or combo boxes that contain only numbers, such as the font size. These objects should support the XAccessibleValue interface.

The current value can be read and set with the getCurrentValue() and setCurrentValue() functions. The valid range of values is returned by the getMaximumValue() and getMinimumValue() functions.
