Class LightweightFrame

java.lang.Object

java.awt.Component

java.awt.Container

java.awt.Window

java.awt.Frame

sun.awt.LightweightFrame

All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

Direct Known Subclasses:

JLightweightFrame

public abstract class LightweightFrame
extends java.awt.Frame

The class provides basic functionality for a lightweight frame implementation. A subclass is expected to provide painting to an offscreen image and access to it. Thus it can be used for lightweight embedding.
