关于SWING的几种布局管理的实例

去年项目组要做关于swing的项目，前期都是学习的阶段。自己就将swing的布局管理以及控件的使用都练习了一遍。

下面是有关swing布局管理的几个实例，希望对初学者有用。

BorderLayout：

import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JFrame;
/**

public class BorderLayoutDemo {

public static void addComponentsToPane(Container pane) {
JButton button = new JButton("[PAGE_START]");
pane.add(button, BorderLayout.PAGE_START);
button = new JButton("[CENTER]");
button.setPreferredSize(new Dimension(200, 100));
pane.add(button, BorderLayout.CENTER);
button = new JButton("[LINE_START]");
pane.add(button, BorderLayout.LINE_START);
button = new JButton("Long Name Button [PAGE_END]");
pane.add(button, BorderLayout.PAGE_END);
button = new JButton("[LINE_END]");
pane.add(button, BorderLayout.LINE_END);
}

private static void createAndShowGUI() {
JFrame frame = new JFrame("BorderLayoutManage");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
addComponentsToPane(frame.getContentPane());
frame.pack();
frame.setVisible(true);
}

public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}

BoxLayout：

import java.awt.BorderLayout;
import java.awt.Component;
import java.awt.Container;
import javax.swing.BoxLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
/**

*/
public class BoxLayoutDemo {
public static void addComponentsToPane(Container pane) {
JPanel xPanel = new JPanel();
xPanel.setLayout(new BoxLayout(xPanel, BoxLayout.X_AXIS));
addButtons(xPanel);
JPanel yPanel = new JPanel();
yPanel.setLayout(new BoxLayout(yPanel, BoxLayout.Y_AXIS));
addButtons(yPanel);

pane.add(yPanel, BorderLayout.PAGE_START);
pane.add(xPanel, BorderLayout.PAGE_END);
}

private static void addAButton(String text, Container container) {
JButton button = new JButton(text);
button.setAlignmentX(Component.CENTER_ALIGNMENT);
container.add(button);
}

private static void addButtons(Container container) {
addAButton("Button 1", container);
addAButton("Button 2", container);
addAButton("Button 3", container);
addAButton("Long Button 4", container);
addAButton("Button 5", container);
}

private static void createAndShowGUI() {
JFrame frame = new JFrame("BoxLayoutManage");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
addComponentsToPane(frame.getContentPane());
frame.pack();
frame.setVisible(true);
}

public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {

});

}
}

import javax.swing.JPanel;
/**

public class CardLayoutDemo {
public void addComponentToPane(Container pane) {
final JPanel contentPanel = new JPanel();
JPanel controlPanel = new JPanel();
final CardLayout cardLayout=new CardLayout();;
pane.setLayout(new BorderLayout());
pane.add(contentPanel, BorderLayout.CENTER);
pane.add(controlPanel, BorderLayout.PAGE_END);
controlPanel.setLayout(new FlowLayout());
JButton[] b = new JButton[10];
for (int i = 0; i < 10; i++) {
b[i] = new JButton("No." + i);
contentPanel.add(b[i]);
}
contentPanel.setLayout(cardLayout);
JButton nextButton = new JButton("Next");
nextButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
cardLayout.next(contentPanel);
}});
controlPanel.add(nextButton);
}

private static void createAndShowGUI() {

demo.addComponentToPane(frame.getContentPane());
frame.pack();
