public class AWTEventDispatcher
extends AbstractAWTEventDispatcher
implements 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.

Constructor Detail

AWTEventDispatcher

public AWTEventDispatcher()

Method Detail

mouseWheelMoved

public void mouseWheelMoved(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 MouseWheelListener

Parameters:

evt - the mouse event to propagate

dispatchEvent

public void dispatchEvent(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(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(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(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(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.
