示例代码:

import javax.swing.UIManager;

public class NotificationPopup extends JDialog {
  private final LinearGradientPaint lpg;

  public NotificationPopup() {
    setUndecorated(true);
    setSize(300, 100);

    // size of the screen
    final Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

    // height of the task bar
    final Insets scnMax = Toolkit.getDefaultToolkit().getScreenInsets(
        getGraphicsConfiguration());
    final int taskBarSize = scnMax.bottom;

    setLocation(screenSize.width - getWidth(), screenSize.height - taskBarSize
        - getHeight());

    // background paint
    lpg = new LinearGradientPaint(0, 0, 0, getHeight() / 2, new float[] { 0f,
        0.3f, 1f }, new Color[] { new Color(0.8f, 0.8f, 1f),
        new Color(0.7f, 0.7f, 1f), new Color(0.6f, 0.6f, 1f) });

    // blue background panel
    setContentPane(new BackgroundPanel());
  }

  private class BackgroundPanel extends JPanel {
    public BackgroundPanel() {
      setOpaque(true);
    }

    @Override

      // background
      g2d.setPaint(lpg);
      g2d.fillRect(1, 1, getWidth() - 2, getHeight() - 2);

      // border
      g2d.drawRect(0, 0, getWidth() - 1, getHeight() - 1);
    }
  }

        }

        final NotificationPopup f = new NotificationPopup();

        final Container c = f.getContentPane();
        c.setLayout(new GridBagLayout());

        final GridBagConstraints constraints = new GridBagConstraints();
        constraints.gridx = 0;
        constraints.gridy = 0;
        constraints.weightx = 1.0f;
        constraints.weighty = 1.0f;
        constraints.insets = new Insets(5, 5, 5, 5);
        constraints.fill = GridBagConstraints.BOTH;

        final JLabel l = new JLabel("You have got 2 new Messages.");
        l.setOpaque(false);

        c.add(l, constraints);

        constraints.fill = GridBagConstraints.NONE;
        constraints.anchor = GridBagConstraints.NORTH;

        final JButton b = new JButton(new AbstractAction("x") {

          @Override
          public void actionPerformed(final ActionEvent e) {
            f.dispose();
          }
        });

        b.setOpaque(false);
        b.setMargin(new Insets(1, 4, 1, 4));
        b.setFocusable(false);

        c.add(b, constraints);

        f.setVisible(true);
      }
    });
  }
