1)AWT(Abstract windows toolkit) 包括了很多类和接口,用于java Application的GUI(Graphics User Interface图形界面编程) 2)GUI的各种元素(窗口,按钮,文本框)等都由java类来实现 3)使用AWT所涉及的类一般在java.awt包及其子包中。 4)Container和Component是AWT中的两个核心
They draw themselves in their parent container and respond to user events in pure Java, with no native code involved. In Swing, only the top-level (lowest API level) windows interact with the windowing system. These Swing containers descend from AWT counterparts, and, thus, still have peers....

Moves the specified component to the specified z-order index in the container. If the component is a child of some other container, it is removed from that container before being added to this container. The important difference between this method andjava.awt.Container.add(Component, int)is ...
Because all Swing components descend from the AWTComponentclass, you can register the following listeners on any Swing component: component listener Listens for changes in the component's size, position, or visibility. focus listener Listens for whether the component gained or lost the keyboard focus...

There are two kinds of graphics components in the Java programming language: heavyweight and lightweight. Aheavyweightcomponent is associated with its own native screen resource (commonly known as apeer). Components from the java.awt package, such as Button and Label, are heavyweight components. Th...
