`getValueIsAdjusting()`

In the previous application the number in the text box changes continuously as the knob is moved. Usually this is desirable. But sometimes the application calls for a great deal of work and you don't want to do it for each change event. There are (potentially) hundreds of change events generated in moving the knob from one value to the next. While the value is still changing the listener should discard the event.

boolean getValueIsAdjusting()

This method returns true while the knob is still moving.
