## 20.10 java.awt.event.ContainerListener (JDK 1.1)

###

This interface defines the methods that an object must implement to "listen" for container events on AWT components. When a `ContainerEvent` occurs, an AWT component notifies its registered `ContainerListener` objects by invoking one of their methods.

An easy way to implement this interface is by subclassing the `ContainerAdapter` class.

    public abstract interface ContainerListener extends EventListener {
        // Public Instance Methods
                public abstract void componentAdded(ContainerEvent e);
                public abstract void componentRemoved(ContainerEvent e);
    }

### Implemented By:

AWTEventMulticaster, ContainerAdapter

### Passed To:

AWTEventMulticaster.add(), AWTEventMulticaster.remove(), Container.addContainerListener(), Container.removeContainerListener()

### Returned By:

AWTEventMulticaster.add(), AWTEventMulticaster.remove()
