java swing组件_Java -- Swing 组件使用

1. 示例1

public class Main {

JFrame f = new JFrame();

Icon okIcon = new ImageIcon("/home/test/start.png"); //图标文件

JButton ok = new JButton("OK", okIcon);

JRadioButton male = new JRadioButton("man", true); //单选按键 group

JRadioButton female = new JRadioButton("woman", false);

ButtonGroup bg = new ButtonGroup();

JCheckBox married = new JCheckBox("married ?", false);

String [] colors = new String[]{"red", "green", "blue"};

JComboBox colorChooser = new JComboBox(colors); //下拉选单，直接添加string[]

JList colorList = new JList(colors);

JTextArea ta = new JTextArea(8, 20);

JTextField name = new JTextField(40);

JMenuBar mb = new JMenuBar(); //菜单栏

JMenu file = new JMenu("file"); //file菜单

JMenu edit = new JMenu("edit");

Icon newIcon = new ImageIcon("/home/test/start.png");

JMenuItem newItem = new JMenuItem("New", newIcon);

Icon saveIcon = new ImageIcon("/home/test/start.png");

JMenuItem saveItem = new JMenuItem("Save", saveIcon);

JMenuItem exitItem = new JMenuItem("Exit", newIcon);

JCheckBoxMenuItem autoWrap = new JCheckBoxMenuItem("AutoWrap");

JPopupMenu pop = new JPopupMenu();

ButtonGroup flavorGroup = new ButtonGroup();

JRadioButtonMenuItem metalItem = new JRadioButtonMenuItem("Metal style", true);

JRadioButtonMenuItem windowsItem = new JRadioButtonMenuItem("Windows style");

public void init()

{

JPanel bottom = new JPanel();

bottom.add(name);

bottom.add(ok);

f.add(bottom, BorderLayout.SOUTH);

JPanel checkPanel = new JPanel();

checkPanel.add(colorChooser);

bg.add(male);

bg.add(female);

checkPanel.add(male);

checkPanel.add(female);

checkPanel.add(married);

Box topLeft = Box.createVerticalBox();

JScrollPane taJsp = new JScrollPane(ta);

topLeft.add(taJsp);

topLeft.add(checkPanel);

Box top = Box.createHorizontalBox();

top.add(topLeft);

top.add(colorList);

f.add(top);

newItem.setAccelerator(KeyStroke.getKeyStroke('N', InputEvent.CTRL_MASK)); //添加快捷键

newItem.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

ta.append("clicked newItem");

}

});

file.add(newItem);

file.add(saveItem);

file.add(exitItem);

edit.add(autoWrap);

edit.setToolTipText("autowrap");

edit.addSeparator();

mb.add(file);

mb.add(edit);

f.setJMenuBar(mb); //设置菜单栏

pop.add(metalItem); //可将这两个item添加到flavorGroup 形成单选

pop.add(windowsItem);

ActionListener flavorListener = new ActionListener() { // 右键单击选项事件

@Override

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

ta.append(e.getActionCommand());

}

};

metalItem.addActionListener(flavorListener);

windowsItem.addActionListener(flavorListener);

ta.setComponentPopupMenu(pop); //设置右键菜单

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //设置X窗口退出

f.pack();

f.setVisible(true);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

new Main().init();

}

}

2. 如上， name输入框中输入后 按Ok Button发送到 ta 中去。。。。为这个动作添加快捷键

Action sendMsg = new AbstractAction() {

@Override

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

ta.append(name.getText());

}

};

ok.addActionListener(sendMsg); //按键添加监听

name.getInputMap().put(KeyStroke.getKeyStroke('\n', java.awt.event.InputEvent.CTRL_MASK ),

"send"); //将Ctrl+Enter 键和"send"关联

name.getActionMap().put("send", sendMsg); //将"send"和 sendMsg Action 关联

3. JColorChooser 和 JFileChooser 。

4. 弹出提示框 showMessageDialog  showConfirmDialog  showInputDialog

public class Main {

JFrame f = new JFrame();

JOptionPane option = new JOptionPane();

JButton bt1 = new JButton("bt1");

JButton bt2 = new JButton("bt2");

JButton bt3 = new JButton("bt3");

JButton bt4 = new JButton("bt4");

Icon icon = new ImageIcon("/home/test/start.png");

public void init()

{

bt1.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) { //消息框

// TODO Auto-generated method stub

option.showMessageDialog(f, "show message", "test", JOptionPane.WARNING_MESSAGE, null);

// Message Type: ERROR_MESSAGE, INFORMATION_MESSAGE, WARNING_MESSAGE, QUESTION_MESSAGE, PLAIN_MESSAGE

}

});

bt2.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) { //确认框

// TODO Auto-generated method stub

int chose = JOptionPane.showConfirmDialog(f, "show message", "test", JOptionPane.OK_CANCEL_OPTION, JOptionPane.WARNING_MESSAGE, icon);

//Option Type: DEFAULT_OPTION, YES_NO_OPTION, YES_NO_CANCEL_OPTION, OK_CANCEL_OPTION

System.out.println(chose);

}

});

bt3.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) { //输入框

// TODO Auto-generated method stub

String str = JOptionPane.showInputDialog(f, "message", "title", JOptionPane.WARNING_MESSAGE);

System.out.println(str);

}

});

f.add(bt1, BorderLayout.SOUTH);

f.add(bt2, BorderLayout.NORTH);

f.add(bt3, BorderLayout.EAST);

f.add(bt4, BorderLayout.WEST);

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.pack();

f.setVisible(true);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

new Main().init();

}

}

5. JSplitPane 分割布局

public class Main {

JFrame f = new JFrame();

JLabel bookList = new JLabel("bookList");

JLabel bookCover = new JLabel("bookCover");

JLabel bookDesc = new JLabel("bookDesc");

public void init()

{

bookList.setPreferredSize(new Dimension(150, 300));

bookCover.setPreferredSize(new Dimension(300, 150));

bookDesc.setPreferredSize(new Dimension(300, 150));

JSplitPane left = new JSplitPane(JSplitPane.VERTICAL_SPLIT, true,

bookCover, new JScrollPane(bookDesc)); //垂直分割

left.setOneTouchExpandable(true); //一处即展 功能

left.resetToPreferredSizes(); //

//left.setDividerSize(50); //设置分隔条大小

JSplitPane content = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,

left, bookList);

f.add(content);

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.pack();

f.setVisible(true);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

new Main().init();

}

}

6. JTabbedPane

public class Main {

JFrame f = new JFrame();

JLabel bookList = new JLabel("bookList");

JLabel bookCover = new JLabel("bookCover");

JLabel bookDesc = new JLabel("bookDesc");

Icon icon = new ImageIcon("/home/test/start.png");

JTabbedPane tab = new JTabbedPane(JTabbedPane.LEFT, JTabbedPane.WRAP_TAB_LAYOUT); //定义tab，靠左 及 Tab排列策越

public void init()

{

bookList.setPreferredSize(new Dimension(150, 300));

bookCover.setPreferredSize(new Dimension(300, 150));

bookDesc.setPreferredSize(new Dimension(300, 150));

tab.addTab("title", icon, bookList, "bookList"); //添加Tab

tab.addTab("title", icon, bookCover, "bookCover");

tab.addTab("title", icon, bookDesc, "bookDesc");

tab.addChangeListener(new ChangeListener() { //Tab事件监听

@Override

public void stateChanged(ChangeEvent e) {

// TODO Auto-generated method stub

System.out.println(tab.getSelectedIndex());

}

});

f.add(tab);

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.pack();

f.setVisible(true);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

new Main().init();

}

}

7. LayeredPane

8. JDesktopPane   JInternalFrame

public class Main {

JFrame f = new JFrame();

JDesktopPane desktop = new JDesktopPane();

public void init()

{

JInternalFrame iframe1 = new JInternalFrame("iframe1", true, true, true, true);

iframe1.reshape(20, 20, 300, 400);

iframe1.show();

JInternalFrame iframe2 = new JInternalFrame("iframe2", true, true, true, true);

iframe2.reshape(20, 20, 300, 400);

iframe2.show();

desktop.setPreferredSize(new Dimension(800, 600));

desktop.add(iframe1);

desktop.add(iframe2);

f.add(desktop);

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.pack();

f.setVisible(true);

}

public static void main(String[] args) {

// TODO Auto-generated method stub

new Main().init();

}

}

9. 进度条

public class Main {

JFrame frame = new JFrame("Test ProgressBar");

JProgressBar bar = new JProgressBar(JProgressBar.VERTICAL );

JCheckBox indeterminate = new JCheckBox("indeterminate");

JCheckBox noBorder = new JCheckBox("noBorder");

JCheckBox dialogCheck = new JCheckBox("dialogCheck");

public void init()

{

final ProgressMonitor dialog = new ProgressMonitor(frame, "ProgressMonitor", "complete", 0, 100);

Box box = new Box(BoxLayout.Y_AXIS);

box.add(indeterminate);

box.add(noBorder);

box.add(dialogCheck);

frame.setLayout(new FlowLayout());

frame.add(box);

bar.setIndeterminate(indeterminate.isSelected());

bar.setStringPainted(!indeterminate.isSelected());

}

});

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.pack();

frame.setVisible(true);

for (int i = 0 ; i <= 100 ; i++)

bar.setValue(i);

dialog.setProgress(i);

try

{

Thread.sleep(100);

}

catch (Exception e)

{

e.printStackTrace();

}

}

}

public static void main(String[] args)

{

new Main().init();

}

}
