public class Main {
  static Color colors[] = { Color.RED, Color.ORANGE, Color.YELLOW, Color.GREEN, Color.BLUE,
      Color.MAGENTA };

  static void add(JTabbedPane tabbedPane, String label) {
    int count = tabbedPane.getTabCount();
    JButton button = new JButton(label);
    button.setBackground(colors[count]);
    tabbedPane.addTab(label, new ImageIcon("yourFile.gif"), button, label);
  }

  public static void main(String args[]) {
    JFrame frame = new JFrame("Tabbed Pane Sample");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JTabbedPane tabbedPane = new JTabbedPane();
    tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
    String titles[] = { "A", "B", "C", "D", "E", "F" };
    for (int i = 0, n = titles.length; i < n; i++) {
      add(tabbedPane, titles[i]);
    }

    frame.add(tabbedPane, BorderLayout.CENTER);
    frame.setSize(400, 150);
    frame.setVisible(true);
  }
}

指定標(biāo)簽的位置:TOP，BOTTOM，LEFT或RIGHT

public class TabLocation {
  static void add(JTabbedPane tabbedPane, String label, int mnemonic) {
    int count = tabbedPane.getTabCount();
    JButton button = new JButton(label);
    tabbedPane.addTab(label, new ImageIcon("yourFile.gif"), button, label);
    tabbedPane.setMnemonicAt(count, mnemonic);
  }

  public static void main(String args[]) {

    JFrame frame = new JFrame("Tabbed Pane Sample");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JTabbedPane tabbedPane = new JTabbedPane();

    String titles[] = { "General", "Security", "Content", "Connection", "Programs", "Advanced" };
    int mnemonic[] = { KeyEvent.VK_G, KeyEvent.VK_S, KeyEvent.VK_C, KeyEvent.VK_O, KeyEvent.VK_P,
        KeyEvent.VK_A };
    for (int i = 0, n = titles.length; i < n; i++) {
      add(tabbedPane, titles[i], mnemonic[i]);
    }

    tabbedPane.setTabPlacement(JTabbedPane.BOTTOM);
    frame.add(tabbedPane, BorderLayout.CENTER);
    frame.setSize(400, 150);
    frame.setVisible(true);
  }
}

改變背景，前景和圖標(biāo)

我們可以使用以下方法更改背景顏色，啟用禁用選項卡。

public void setBackgroundAt(int index, Color background)
public void setForegroundAt(int index, Color foreground)
public void setEnabledAt(int index, boolean enabled)
public void setDisabledIconAt(int index, Icon disabledIcon)

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.event.KeyEvent;
/*ww  w. j  a va 2  s.com*/
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTabbedPane;

public class Main {
  static Color colors[] = { Color.RED, Color.ORANGE, Color.YELLOW, Color.GREEN, Color.BLUE,
      Color.MAGENTA };

  static void add(JTabbedPane tabbedPane, String label, int mnemonic) {
    int count = tabbedPane.getTabCount();
    JButton button = new JButton(label);
    tabbedPane.addTab(label, new ImageIcon("yourFile.gif"), button, label);
    tabbedPane.setMnemonicAt(count, mnemonic);
  }

  public static void main(String args[]) {
    JFrame frame = new JFrame("Tabbed Pane Sample");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JTabbedPane tabbedPane = new JTabbedPane();
    String titles[] = { "General", "Security", "Content", "Connection", "Programs", "Advanced" };
    int mnemonic[] = { KeyEvent.VK_G, KeyEvent.VK_S, KeyEvent.VK_C, KeyEvent.VK_O, KeyEvent.VK_P,
        KeyEvent.VK_A };
    for (int i = 0, n = titles.length; i < n; i++) {
      add(tabbedPane, titles[i], mnemonic[i]);
      tabbedPane.setBackgroundAt(i,colors[i]);
    }
    frame.add(tabbedPane, BorderLayout.CENTER);
    frame.setSize(400, 150);
    frame.setVisible(true);
  }
}

刪除標(biāo)簽

要刪除選項卡，您可以使用刪除特定選項卡removeTabAt(int index)，remove(int index)或remove(Component component)

使用removeAll()刪除所有選項卡

import java.awt.BorderLayout;
import java.awt.event.KeyEvent;
//w  w  w.  j  av a 2s .c o  m
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTabbedPane;

public class Main {

  static void add(JTabbedPane tabbedPane, String label, int mnemonic) {
    int count = tabbedPane.getTabCount();
    JButton button = new JButton(label);
    tabbedPane.addTab(label, new ImageIcon("yourFile.gif"), button, label);
    tabbedPane.setMnemonicAt(count, mnemonic);
  }

  public static void main(String args[]) {
    JFrame frame = new JFrame("Tabbed Pane Sample");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JTabbedPane tabbedPane = new JTabbedPane();
    tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT);
    String titles[] = { "General", "Security", "Content", "Connection", "Programs", "Advanced" };
    int mnemonic[] = { KeyEvent.VK_G, KeyEvent.VK_S, KeyEvent.VK_C, KeyEvent.VK_O, KeyEvent.VK_P,
        KeyEvent.VK_A };
    for (int i = 0, n = titles.length; i < n; i++) {
      add(tabbedPane, titles[i], mnemonic[i]);
    }

    tabbedPane.removeAll();
    frame.add(tabbedPane, BorderLayout.CENTER);
    frame.setSize(400, 150);
    frame.setVisible(true);
  }
}

        int index = sourceTabbedPane.getSelectedIndex();
        System.out.println("Tab changed to: " + sourceTabbedPane.getTitleAt(index));
      }
    };
    tabbedPane.addChangeListener(changeListener);
    frame.add(tabbedPane, BorderLayout.CENTER);
    frame.setSize(400, 150);
    frame.setVisible(true);
