Java图形化
基本窗口类:Frame Dialog
基本GUI类:Button Label TextField TextArea CheckBox
基本事件接口:ActionListener WindowListener MouseListener KeyListener
基本布局接口:FlowLayout BorderLayout GridLayout Panel
基本画图支持:Graphics Canvas
Frame类的定义:
public class Frame extends Window implements MenuContainer
{
public Frame()
public Frame(String title)
public String getTitle()
public void setTitle(String title)
public MenuBar getMenuBar()
public void setMenuBar(MenuBar mb)
public void dispose()
}
Button类的定义:
public class Buttom extends Component
{
public Button()
public Button(String label)
public String getLabel()
public void setLabel(String label)
public void addActionListener(ActionListener l)
public void removeActionListener(ActionListener l)
}
TextField类的定义:
public class TextField extends TextComponent
{
public TextField()
public TextField(String text)
public TextField(int columns)
public TextField(String text,int columns)
public void addActionListener(ActionListener l)
public void removeActionListener(ActionListener l)
}
Applet类的定义:
public class Applet extends Panel
{
public Applet()
public String getParameter(String name)
public AppletContext getAppletContext()
public void showSataus(String msg)
//被加载时,init()方法被调用一次,与构造方法类似,可以重载,提供不同的初始化代码
public void init()
//Applet被再次访问时,start方法被调用,start方法可以被重载以产生更好的效果
public void start()
//当包含Applet的Web页面被其它页面替换时,stop方法被调用。用户离开一个web页面时,stop方法都会产生相应的动作,比如关闭一个动画
public void stop()
public URL getCodeBase()
public URL getDocumentBase()
}
