Class ZMouseMotionAdapter
java.lang.Object
|
+--edu.umd.cs.jazz.event.ZMouseMotionAdapter
- All Implemented Interfaces:
- java.util.EventListener, ZMouseMotionListener
- public abstract class ZMouseMotionAdapter
- extends java.lang.Object
- implements ZMouseMotionListener
ZMouseMotionAdapter is an abstract adapter class for receiving mouse motion events.
The methods in this class are empty. This class exists as
convenience for creating listener objects.
Mouse motion events occur when a mouse is moved or dragged.
(Many such events will be generated in a normal program.
To track clicks and other mouse events, use the MouseAdapter.)
Extend this class to create a ZMouseMotionEvent
listener
and override the methods for the events of interest. (If you implement the
ZMouseMotionListener
interface, you have to define all of
the methods in it. This abstract class defines null methods for them
all, so you can only have to define methods for events you care about.)
Create a listener object using the extended class and then register it with
a node using the node's addMouseMotionListener
method. When the mouse is moved or dragged, the relevant method in the
listener object is invoked and the ZMouseEvent
is passed to it.

ZMouseMotionAdapter
public ZMouseMotionAdapter()
mouseDragged
public void mouseDragged(ZMouseEvent e)
- Invoked when a mouse button is pressed on a node and then
dragged. Mouse drag events will continue to be delivered to
the node where the first originated until the mouse button is
released (regardless of whether the mouse position is within the
bounds of the node).
- Specified by:
mouseDragged
in interface ZMouseMotionListener
mouseMoved
public void mouseMoved(ZMouseEvent e)
- Invoked when the mouse button has been moved on a node
(with no buttons no down).
- Specified by:
