All Implemented Interfaces:

java.io.Serializable

public class AdjustmentEvent extends AWTEvent
The adjustment event emitted by Adjustable objects like Scrollbar and ScrollPane. When the user changes the value of the scrolling component, it receives an instance of AdjustmentEvent.
An unspecified behavior will be caused if the id parameter of any particular AdjustmentEvent instance is not in the range from ADJUSTMENT_FIRST to ADJUSTMENT_LAST.
The type of any AdjustmentEvent instance takes one of the following values:
- UNIT_INCREMENT
- UNIT_DECREMENT
- BLOCK_INCREMENT
- BLOCK_DECREMENT
- TRACK
Assigning the value different from listed above will cause an unspecified behavior.
Since:

1.1
