org.apache.batik.gvt.event.EventDispatcher

All known Subclasses:   org.apache.batik.gvt.event.AbstractAWTEventDispatcher,
EventDispatcher
public interface EventDispatcher (Code)
Interface for receiving and dispatching events down to a GVT tree.

Mouse events are dispatched to their "containing" node (the GraphicsNode corresponding to the mouse event coordinate). Searches for containment are performed from the EventDispatcher's "root" node.

Method Summary
 voidaddGraphicsNodeKeyListener(GraphicsNodeKeyListener l)
     Adds the specified 'global' GraphicsNodeKeyListener which is notified of all KeyEvents dispatched.
 voidaddGraphicsNodeMouseListener(GraphicsNodeMouseListener l)
     Adds the specified 'global' GraphicsNodeMouseListener which is notified of all MouseEvents dispatched.
 voidaddGraphicsNodeMouseWheelListener(GraphicsNodeMouseWheelListener l)
     Adds the specified 'global' GraphicsNodeMouseWheelListener which is notified of all MouseWheelEvents dispatched.
 voiddispatchEvent(EventObject e)
     Dispatched the specified event object.

Converts the EventObject to a corresponding GraphicsNodeEvent and dispatch it to the appropriate GraphicsNode(s).

 AffineTransformgetBaseTransform()
     Returns the base transform applied to MouseEvent coordinates prior to dispatch.
 EventListener[]getListeners(Class listenerType)
     Returns an array of listeners that were added to this event dispatcher and of the specified type.
 GraphicsNodegetRootNode()
     Returns the root node for MouseEvent dispatch containment searches and field selections.
 voidremoveGraphicsNodeKeyListener(GraphicsNodeKeyListener l)
     Removes the specified 'global' GraphicsNodeKeyListener which is notified of all KeyEvents dispatched.
 voidremoveGraphicsNodeMouseListener(GraphicsNodeMouseListener l)
     Removes the specified 'global' GraphicsNodeMouseListener which is notified of all MouseEvents dispatched.

 voidsetBaseTransform(AffineTransform t)
     Sets the base transform applied to MouseEvent coordinates prior to dispatch.
 voidsetNodeDecrementEvent(InputEvent e)
     Associates all InputEvents of type e.getID() with "decrementing" of the currently selected GraphicsNode.
 voidsetNodeIncrementEvent(InputEvent e)
     Associates all InputEvents of type e.getID() with "incrementing" of the currently selected GraphicsNode.
 voidsetRootNode(GraphicsNode root)
     Sets the root node for MouseEvent dispatch containment searches and field selections.



Method Detail
addGraphicsNodeKeyListener
void addGraphicsNodeKeyListener(GraphicsNodeKeyListener l)(Code)
Adds the specified 'global' GraphicsNodeKeyListener which is notified of all KeyEvents dispatched.
Parameters:
  l - the listener to add



addGraphicsNodeMouseListener
void addGraphicsNodeMouseListener(GraphicsNodeMouseListener l)(Code)
Adds the specified 'global' GraphicsNodeMouseListener which is notified of all MouseEvents dispatched.
Parameters:
  l - the listener to add



addGraphicsNodeMouseWheelListener
void addGraphicsNodeMouseWheelListener(GraphicsNodeMouseWheelListener l)(Code)
Adds the specified 'global' GraphicsNodeMouseWheelListener which is notified of all MouseWheelEvents dispatched.
Parameters:
  l - the listener to add



dispatchEvent
void dispatchEvent(EventObject e)(Code)
Dispatched the specified event object.

Converts the EventObject to a corresponding GraphicsNodeEvent and dispatch it to the appropriate GraphicsNode(s). If the event is a MouseEvent the dispatch is performed to each GraphicsNode which contains the MouseEvent coordinate, until the event is consumed. If the event is a KeyEvent, it is dispatched to the currently selected GraphicsNode.


Parameters:
  e - the event to dispatch



getBaseTransform
AffineTransform getBaseTransform()(Code)
Returns the base transform applied to MouseEvent coordinates prior to dispatch.



getListeners
EventListener[] getListeners(Class listenerType)(Code)
Returns an array of listeners that were added to this event dispatcher and of the specified type.
Parameters:
  listenerType - the type of the listeners to return



getRootNode
GraphicsNode getRootNode()(Code)
Returns the root node for MouseEvent dispatch containment searches and field selections.



removeGraphicsNodeKeyListener
void removeGraphicsNodeKeyListener(GraphicsNodeKeyListener l)(Code)
Removes the specified 'global' GraphicsNodeKeyListener which is notified of all KeyEvents dispatched.
Parameters:
  l - the listener to remove



removeGraphicsNodeMouseListener
void removeGraphicsNodeMouseListener(GraphicsNodeMouseListener l)(Code)
Removes the specified 'global' GraphicsNodeMouseListener which is notified of all MouseEvents dispatched.
Parameters:
  l - the listener to remove



removeGraphicsNodeMouseWheelListener
void removeGraphicsNodeMouseWheelListener(GraphicsNodeMouseWheelListener l)(Code)
Removes the specified 'global' GraphicsNodeMouseWheelListener which is notified of all MouseWheelEvents dispatched.
Parameters:
  l - the listener to remove



setBaseTransform
void setBaseTransform(AffineTransform t)(Code)
Sets the base transform applied to MouseEvent coordinates prior to dispatch.
Parameters:
  t - the affine transform



setNodeDecrementEvent
void setNodeDecrementEvent(InputEvent e)(Code)
Associates all InputEvents of type e.getID() with "decrementing" of the currently selected GraphicsNode. The notion of "currently selected" GraphicsNode is used for dispatching KeyEvents.



setNodeIncrementEvent
void setNodeIncrementEvent(InputEvent e)(Code)
Associates all InputEvents of type e.getID() with "incrementing" of the currently selected GraphicsNode.



setRootNode
void setRootNode(GraphicsNode root)(Code)
Sets the root node for MouseEvent dispatch containment searches and field selections.
Parameters:
  root - the root node
