MouseAdapter

Class Overview

An abstract adapter class for receiving mouse events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Mouse events let you track when a mouse is pressed, released, clicked, moved, dragged, when it enters a component, when it exits and when a mouse wheel is moved.

Extend this class to create a MouseEvent (including drag and motion events) or/and MouseWheelEvent listener and override the methods for the events of interest. (If you implement the MouseListener, MouseMotionListener 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 component using the component's addMouseListener addMouseMotionListener, addMouseWheelListener methods. The relevant method in the listener object is invoked and the MouseEvent or MouseWheelEvent is passed to it in following cases:

• when a mouse button is pressed, released, or clicked (pressed and released)
• when the mouse cursor enters or exits the component
• when the mouse wheel rotated, or mouse moved or dragged

Summary

[Expand] Inherited Methods
From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object. final void wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long timeout) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed.
From interface java.awt.event.MouseListener abstract void mouseClicked(MouseEvent e) Invoked when the mouse button has been clicked (pressed and released) on a component. abstract void mouseEntered(MouseEvent e) Invoked when the mouse enters a component. abstract void mouseExited(MouseEvent e) Invoked when the mouse exits a component. abstract void mousePressed(MouseEvent e) Invoked when a mouse button has been pressed on a component. abstract void mouseReleased(MouseEvent e) Invoked when a mouse button has been released on a component.
From interface java.awt.event.MouseMotionListener abstract void mouseDragged(MouseEvent e) Invoked when a mouse button is pressed on a component and then dragged. abstract void mouseMoved(MouseEvent e) Invoked when the mouse cursor has been moved onto a component but no buttons have been pushed.
From interface java.awt.event.MouseWheelListener abstract void mouseWheelMoved(MouseWheelEvent e) Invoked when the mouse wheel is rotated.
