java.awt.event
Interface ContainerListener

All Superinterfaces:

EventListener

All Known Implementing Classes:

AWTEventMulticaster, BasicToolBarUI.ToolBarContListener, Container.AccessibleAWTContainer.AccessibleContainerHandler, ContainerAdapter, JComponent.AccessibleJComponent.AccessibleContainerHandler, MetalToolBarUI.MetalContainerListener

public interface ContainerListener
extends EventListener

The listener interface for receiving container events. The class that is interested in processing a container event either implements this interface (and all the methods it contains) or extends the abstract ContainerAdapter class (overriding only the methods of interest). The listener object created from that class is then registered with a component using the component's addContainerListener method. When the container's contents change because a component has been added or removed, the relevant method in the listener object is invoked, and the ContainerEvent is passed to it.

Container events are provided for notification purposes ONLY; The AWT will automatically handle add and remove operations internally so the program works properly regardless of whether the program registers a ComponentListener or not.

1.1
