JFrame that pops-up from the taskbar like notifications.

programming

Here i have given the JAVA code to make a popup that happens exactly like the gmail desktop application does.It uses a JFrame to make the window.

package com.oksbwn.popUp;
import java.awt.*;
import java.awt.event.*;

import javax.swing.*;

import com.oksbwn.ErrorHandling.handleExceptions;

import resources.RscLoader;

public class popMe extends JFrame {
    private static final long serialVersionUID = 1 L;
    public static void main(String[] args) throws Exception {
        new popMe("hi", "from Bikash", "ok", 15, 125);
    }
    public popMe(String message, String header, String image, final int time, int height) {

        Runnable r = new newThreadPop(message, header, image, time, height);
        new Thread(r).start();
    }
}

class newThreadPop implements Runnable {
    private String message;
    private String header;
    private String image;
    private int time;
    private int height;

    public newThreadPop(String message1, String header1, String image1, final int time1, int height1) {
        // store parameter for later user
        this.message = message1;
        this.header = header1;
        this.image = image1;
        this.time = time1;
        this.height = height1;
    }

    public void run() {
        final Runnable runnable = (Runnable) Toolkit.getDefaultToolkit().getDesktopProperty("win.sound.exclamation");
        //default
        if (runnable != null)
            runnable.run();
        final JFrame frame = new JFrame();
        frame.setUndecorated(true);
        frame.setType(javax.swing.JFrame.Type.UTILITY);
        frame.setUndecorated(true);
        frame.setBackground(new Color(Color.black.getRed(), Color.black.getGreen(), Color.black.getBlue(), 0));
        ((JComponent) frame.getContentPane()).setBorder(
            BorderFactory.createMatteBorder(2, 2, 2, 2, Color.black));
        frame.setSize(300, height);
        frame.setLayout(new GridBagLayout());
        GridBagConstraints constraints = new GridBagConstraints();
        constraints.gridx = 0;
        constraints.gridy = 0;
        constraints.weightx = 1.0 f;
        constraints.weighty = 1.0 f;
        constraints.insets = new Insets(5, 5, 5, 5);
        constraints.fill = GridBagConstraints.BOTH;
        JLabel headingLabel = new JLabel(header);
        headingLabel.setForeground(Color.red);
        ImageIcon headingIcon = new ImageIcon(RscLoader.getImage(image));
        headingLabel.setIcon(headingIcon); // --- use image icon you want to be as heading image.
        headingLabel.setOpaque(false);
        frame.add(headingLabel, constraints);
        constraints.gridx++;
        constraints.weightx = 0 f;
        constraints.weighty = 0 f;
        constraints.fill = GridBagConstraints.NONE;
        constraints.anchor = GridBagConstraints.NORTH;

        final JLabel lblX = new JLabel("X");
        lblX.setToolTipText("Closern");
        lblX.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent arg0) {
                frame.dispose();
            }
            @Override
            public void mouseEntered(MouseEvent e) {
                lblX.setForeground(new Color(255, 0, 0));
            }
            public void mouseExited(MouseEvent e) {
                lblX.setForeground(new Color(0, 0, 0));
            }
        });
        lblX.setSize(10, 10);
        lblX.setFocusable(false);
        frame.add(lblX, constraints);
        constraints.gridx = 0;
        constraints.gridy++;
        constraints.weightx = 1.0 f;
        constraints.weighty = 1.0 f;
        constraints.insets = new Insets(5, 5, 5, 5);
        constraints.fill = GridBagConstraints.BOTH;
        JLabel messageLabel = new JLabel("" + message);
        messageLabel.setForeground(Color.blue);
        frame.add(messageLabel, constraints);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setVisible(true);
        frame.setAlwaysOnTop(true);
        Dimension scrSize = Toolkit.getDefaultToolkit().getScreenSize(); // size of the screen
        Insets toolHeight = Toolkit.getDefaultToolkit().getScreenInsets(frame.getGraphicsConfiguration()); // height of the task bar
        frame.setLocation(scrSize.width - frame.getWidth(), scrSize.height - toolHeight.bottom - frame.getHeight());
        new Thread() {
            @Override
            public void run() {
                try {
                    Thread.sleep(time * 1000); // time after which pop up will be disappeared.
                    frame.dispose();
                } catch (Exception e) {
                    new handleExceptions(e);
                }
            };
        }.start();

    }
}
