## 20.4 java.awt.event.AdjustmentListener (JDK 1.1)

###

This interface defines the method that an object must implement to "listen" for adjustment events on AWT components. When an `AdjustmentEvent` occurs, an AWT component notifies its registered `AdjustmentListener` objects by invoking their `adjustmentValueChanged()` methods.

    public abstract interface AdjustmentListener extends EventListener {
        // Public Instance Methods
                public abstract void adjustmentValueChanged(AdjustmentEvent e);
    }

### Implemented By:

`AWTEventMulticaster`

### Passed To:

`Adjustable.addAdjustmentListener(), Adjustable.removeAdjustmentListener(), AWTEventMulticaster.add(), AWTEventMulticaster.remove(), Scrollbar.addAdjustmentListener(), Scrollbar.removeAdjustmentListener()`

### Returned By:

`AWTEventMulticaster.add(), AWTEventMulticaster.remove()`
