Question

java 卡片布局问题

在 Windows桌面上 单击鼠标右键 再选择属性 这个窗口的上面有
"主题" "桌面" "屏幕保护程序" 等 之类的卡片布局窗口 请问怎么用JAVA实现这种卡片布局呢? 请高手指点.

Answer 1

先添加一个面板，把布局设置成CardLayout然后再向这个面板中添加新的面板。。就可以了。。。然后面板的转换用按钮做，给按钮添加单击事件。

这是用面板布局做的一个简单示例，你可以看一下，在JBUilder里面写的，可能不能运行。但你可以借鉴一下。

楼主说的应该是JTabbedPane吧，给你个小程序研究下

import java.awt.BorderLayout;
import java.awt.Container;

import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTabbedPane;
import javax.swing.JTextField;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;

public class TabbedPane1 extends JApplet {
private String[] flavors = { "Chocolate", "Strawberry",
"Vanilla Fudge Swirl", "Mint Chip", "Mocha Almond Fudge",
"Rum Raisin", "Praline Cream", "Mud Pie" };

private JTabbedPane tabs = new JTabbedPane();

private JTextField txt = new JTextField(20);

public void init() {
for (int i = 0; i < flavors.length; i++)
tabs.addTab(flavors[i], new JButton("Tabbed pane " + i));
tabs.addChangeListener(new ChangeListener() {
public void stateChanged(ChangeEvent e) {
txt.setText("Tab selected: " + tabs.getSelectedIndex());
}
});
Container cp = getContentPane();
cp.add(BorderLayout.SOUTH, txt);
cp.add(tabs);
}

public static void main(String[] args) {
run(new TabbedPane1(), 350, 200);
}

public static void run(JApplet applet, int width, int height) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(applet);
frame.setSize(width, height);
applet.init();
applet.start();
frame.setVisible(true);
}
}
