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

        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);
