ComponentAdapter

Class Overview

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

Extend this class to create a ComponentEvent listener and override the methods for the events of interest. (If you implement the ComponentListener 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 your class and then register it with a component using the component's addComponentListener method. When the component's size, location, or visibility changes, the relevant method in the listener object is invoked, and the ComponentEvent is passed to it.

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.ComponentListener abstract void componentHidden(ComponentEvent e) Invoked when the component has been made invisible. abstract void componentMoved(ComponentEvent e) Invoked when the component's position changes. abstract void componentResized(ComponentEvent e) Invoked when the component's size changes. abstract void componentShown(ComponentEvent e) Invoked when the component has been made visible.
