# Class SwingEventMonitor

java.lang.Object
com.sun.java.accessibility.util.AWTEventMonitor
com.sun.java.accessibility.util.SwingEventMonitor

public class SwingEventMonitor extends AWTEventMonitor

`SwingEventMonitor` extends `AWTEventMonitor` by adding a suite of listeners conditionally installed on every Swing component instance in the Java Virtual Machine. The events captured by these listeners are made available through a unified set of listeners supported by `SwingEventMonitor`. With this, all the individual events on each of the AWT and Swing component instances are funneled into one set of listeners broken down by category (see `EventID` for the categories).

This class depends upon `EventQueueMonitor`, which provides the base level support for capturing the top-level containers as they are created.

Because this class extends `AWTEventMonitor`, it is not necessary to use this class and `AWTEventMonitor` at the same time. If you want to monitor both AWT and Swing components, you should use just this class.
