如何进行Java GUI图形用户界面编程

Answer 1

在远标做过直接使用javax.swing和java.awt两个包
一个简单的GUI程序如下：
packagesix;
importjavax.swing.*;
importjava.awt.*;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
publicclassMain extendsJFrame{ //类Main继承自JFrame
privateJPanel pane = null;
privateJPanel p = null;
privateCardLayout card = null;
privateJButton button_1 = null;
privateJButton button_2 = null;
privateJButton b1 = null,b2 = null,b3 = null;
privateJPanel p1 = null,p2 = null,p3 = null;
publicMain() //
{
super("卡片布局管理器测试");
try{
UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
}
catch(Exception ex){
ex.printStackTrace();
}
//创建新卡片布局
card = newCardLayout(5,5);
pane = newJPanel(card);
p = newJPanel();
button_1 = newJButton("< 上一步");
button_2 = newJButton("下一步 >");
b1 = newJButton("1");b2 = newJButton("2");b3 = newJButton("3");
b1.setMargin(newInsets(2,2,2,2));
b2.setMargin(newInsets(2,2,2,2));
b3.setMargin(newInsets(2,2,2,2));
p.add(button_1);p.add(b1);p.add(b2);p.add(b3);p.add(button_2);
p1 = newJPanel();
p2 = newJPanel();
p3 = newJPanel();
p1.setBackground(Color.RED);
p2.setBackground(Color.BLUE);
p3.setBackground(Color.GREEN);
p1.add(newJLabel("JPanel_1"));
p2.add(newJLabel("JPanel_2"));
p3.add(newJLabel("JPanel_3"));
pane.add(p1,"p1");pane.add(p2,"p2");pane.add(p3,"p3");
//翻转卡片布局动作
button_1.addActionListener(newActionListener(){
publicvoidactionPerformed(ActionEvent e){
card.previous(pane);
}
});
button_2.addActionListener(newActionListener(){
publicvoidactionPerformed(ActionEvent e){
card.next(pane);
}
});
b1.addActionListener(newActionListener(){
publicvoidactionPerformed(ActionEvent e){
card.show(pane, "p1");
}
});
b2.addActionListener(newActionListener(){
publicvoidactionPerformed(ActionEvent e){
card.show(pane,"p2");
}
});
b3.addActionListener(newActionListener(){
publicvoidactionPerformed(ActionEvent e){
card.show(pane, "p3");
}
});
this.getContentPane().add(pane);
this.getContentPane().add(p,BorderLayout.SOUTH);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(300, 200);
this.setVisible(true);
}
publicstaticvoidmain(String[]args)
{
newMain(); //
}
}
