Question

Answer 1

Here is your notification Popup:

Code with an example:

import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.LinearGradientPaint;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;

import javax.swing.AbstractAction;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
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
    protected void paintComponent(final Graphics g) {
      final Graphics2D g2d = (Graphics2D) g;
      // background
      g2d.setPaint(lpg);
      g2d.fillRect(1, 1, getWidth() - 2, getHeight() - 2);
      g2d.setColor(Color.BLACK);

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

  public static void main(final String[] args) {

    SwingUtilities.invokeLater(new Runnable() {
      @Override
      public void run() {
        try {
          UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        } catch (final Exception e1) {
          e1.printStackTrace();
        }

        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.gridx++;
        constraints.weightx = 0f;
        constraints.weighty = 0f;
        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);
      }
    });
  }
}

Answer 2

You will need to take a look at the System Tray API . The displayIcon method should do what you need:

Displays a pop-up message next to the tray icon. The message will disappear after a time or the user clicks on it. Clicking on a message can trigger an ActionEvent.

Answer 3

unecorated JFrame (frame.setUndecorated(true)) Toolkit.getDefaultToolkit(). getScreenSize().

Answer 4

You can use JTelegraph to get a bright popup. All you have to do is get its jar file (you also need to get two more jar files with it) and include it in your build path and start coding.
