•  this.setAutoRequestFocus(true);

•  this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

•  this.setResizable(true);

•  this.setEnabled(true);

•  this.setSize(100,200);

• this.setOpacity((float)1.0);// 当前窗体被系统修饰以后，只能opacity给1.0
  this.setUndecorated(true);//当前窗体不被系统装饰, 最小化，最大化，关闭按钮都没有
                              //要自己添加按钮进行关闭等操作

• this.setType(Type.POPUP);
  //        this.setType(Type.NORMAL);
  //        this.setType(Type.UTILITY);  //根据type，系统修饰的方式略有不同

• setVisible(true)

• JPanel panel1 = new JPanel();
  this.setContentPane(panel1); 要给JFrame设置一个contentPane
  

  
  

JPanel

Container中可以放控件，或者其他容器。

常用属性

• JPanel panel1 = new JPanel();

• panel1.setBackground(Color.BLUE);

• panel1.setLayout(new FlowLayout());  //JPanel default layout ==> borderlayout

• panel1.setBorder(new TitledBorder("panel1"));

  
  

其他Containter

JLabel

• JLabel lbl1 = new JLabel();

•  lbl1.setFont(new Font("MS Mincho", Font.BOLD, 14));

•  lbl1.setText("lbl1");

•  lbl1.setForeground(Color.BLACK);

•  lbl1.setIcon(new ImageIcon(this.getClass().getResource("icon1.png")));

• 
  

•  lbl1.setToolTipText("tool tip");

• 文本对齐方式：
  

•  lbl1.setHorizontalAlignment(SwingConstants.CENTER);

•  lbl1.setVerticalAlignment(SwingConstants.TOP);

JButton

常用属性

 JButton btn1 = new JButton("btn1");
         btn1.addMouseListener(new MouseAdapter() {
             @Override
             public void mouseClicked(MouseEvent e) {
                 System.out.println("1");
             }
         });

JTextField 单行文本框

常用属性

 TextField jtf1 = new JTextField();
         jtf1.setEnabled(true);
         jtf1.setEditable(false);
         jtf1.setText("du text");

JTextArea 多行文本框

常用属性

 JTextArea ta = new JTextArea();
 ta.setRows(5);
 ta.setColumns(10);
 ta.setLineWrap(true);// default : false

JScrollPane

把ta放在JScrollPane中的viewportview中，然后把JScrollPane放在panel中

 JScrollPane scrollPane = new JScrollPane();
         scrollPane.setViewportView(ta);
         panel1.add(scrollPane);

JRadioButton,JCheckBox

把rb加到buttongroup中，但是jpanel中加的是rb

 JRadioButton rb1 = new JRadioButton("rb1");
 rb1.setSelected(true);
 System.out.println(rb1.isSelected());
 JRadioButton rb2 = new JRadioButton("rb2");
 JRadioButton rb3 = new JRadioButton();
 rb3.setText("rb3");
 ButtonGroup btnGr = new ButtonGroup();
 btnGr.add(rb1);
 btnGr.add(rb2);
 btnGr.add(rb3);
 panel1.add(rb1);
 panel1.add(rb2);
 panel1.add(rb3);

JList

给List设置model数据

 lstName = new JList<String>();
 lstName.setModel(new AbstractListModel<String>() {
     private String[] values = new String[]{"java", "c++", "c#"};
     @Override
     public int getSize() {
         return values.length;
     }
     @Override
     public String getElementAt(int index) {
         return values[index];
     }
 });

常用方法：

 lstName.getSelectedValue();
 lstName.getSelectedIndex();
 lstName.getSelectedIndices();
 lstName.getSelectedValuesList();
 lstName.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

• 如果不选择任何项，selectedIndex是-1.
• 默认selectionmode是可选多行
  

JComboBox

 String[] values = new String[]{"java", "c++", "c#"};
 comboCours = new JComboBox<String>(values);
 comboCours.addItemListener(new ItemListener() {
     @Override
     public void <span style="background-color: rgb(255, 255, 102);">itemStateChanged</span>(ItemEvent e) {
         System.out.println(comboCours.getSelectedItem());
     }
 });
 panel1.add(comboCours);

JProgressBar

 progressBar = new JProgressBar();
 progressBar.setMinimum(0);
 progressBar.setMaximum(100);

用swingworker多线程控制JprogressBar：

 panel1.add(progressBar);
         JButton btnPB = new JButton("add");
         btnPB.addMouseListener(new MouseAdapter() {
             @Override
             public void mouseClicked(MouseEvent e) {
                 new SwingWorker<String,Integer>(){

                     @Override
                     protected String doInBackground() throws Exception {
                         for (int i = 0; i <=10; i++ ) {
                             Thread.sleep(1000);//sleep for 1s
                             publish(i*10);
                         }
                         return null;
                     }

                     @Override
                     protected void process(List<Integer> chunks) {
                         for(Integer integer : chunks){
                             progressBar.setValue(integer);
                         }
                     }
                 }.execute();
             }
         });
         panel1.add(btnPB);

JSpinner数字调节控件

model是数字：

 JSpinner spinner1 = new JSpinner();
 spinner1.setModel(new SpinnerNumberModel(60,0,100,1));
                     //int value, int minimum, int maximum, int stepSize
                     //double, double,double,double
 panel1.add(spinner1);

 int num = Integer.parseInt(spinner1.getValue().toString());
 System.out.println(num);

model是日期：

 JSpinner spinner2 = new JSpinner();
 spinner2.setModel(new SpinnerDateModel());
 panel1.add(spinner2);
