```
public class AWTEventDispatcher
extends AbstractAWTEventDispatcher
implements java.awt.event.MouseWheelListener
```
A concrete version of AWTEventDispatcher. This class is used for JDKs >= 1.4, which have MouseWheelEvent support. For JDKs < 1.4, the file sources-1.3/org/apache/batik/gvt/event/AWTEventDispatcher defines a version of this class that does not support MouseWheelEvents.

public AWTEventDispatcher()
```
- Method Detail
  - mouseWheelMoved
```
public void mouseWheelMoved(java.awt.event.MouseWheelEvent evt)
```
    Dispatches the specified AWT mouse wheel event down to the GVT tree. The mouse wheel event is mutated to a GraphicsNodeMouseWheelEvent.
    
    Specified by:
    
    mouseWheelMoved in interface java.awt.event.MouseWheelListener
    
    Parameters:
    evt - the mouse event to propagate
  - dispatchEvent
```
public void dispatchEvent(java.util.EventObject evt)
```
    Dispatches the specified AWT event.
    
    Specified by:
    
    dispatchEvent in interface EventDispatcher
    
    Overrides:
    
    dispatchEvent in class AbstractAWTEventDispatcher
    
    Parameters:
    evt - the event to dispatch
  - dispatchMouseWheelEvent
```
protected void dispatchMouseWheelEvent(java.awt.event.MouseWheelEvent evt)
```
    Dispatches the specified AWT mouse wheel event.
    
    Parameters:
    evt - the mouse wheel event to dispatch
  - processMouseWheelEvent
```
protected void processMouseWheelEvent(GraphicsNodeMouseWheelEvent evt)
```
    Processes the specified event by firing the 'global' listeners attached to this event dispatcher.
    
    Parameters:
    evt - the event to process
  - dispatchKeyEvent
```
protected void dispatchKeyEvent(java.awt.event.KeyEvent evt)
```
    Dispatches the specified AWT key event.
    
    Specified by:
    
    dispatchKeyEvent in class AbstractAWTEventDispatcher
    
    Parameters:
    evt - the key event to dispatch
  - getModifiers
```
protected int getModifiers(java.awt.event.InputEvent evt)
```
    Returns the modifiers mask for this event. This just calls InputEvent.getModifiersEx() on evt.
    
    Specified by:
    
    getModifiers in class AbstractAWTEventDispatcher
  - getButton
```
protected int getButton(java.awt.event.MouseEvent evt)
```
    Returns the button whose state changed for the given event. This just calls MouseEvent.getButton().
    
    Specified by:
    
    getButton in class AbstractAWTEventDispatcher
  - isMetaDown
```
protected static boolean isMetaDown(int modifiers)
```
    Returns whether the meta key is down according to the given modifiers bitfield.
