How to create system notification popup like outlook using Swing in java
It would be very easy to make system notification pop up like Microsoft outlook in swing.
I have created following two java classes to make system notification works. First class handled the basic and core level implementation like creating a form and making AWT api to work. Second class is used for testing purpose.1. NotificationPopup.java
package com.vsquaresolution.system.nofitifcation;
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 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, 50);
// 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(1f, 1f, 1f), new Color(1f, 1f, 1f),
new Color(1f, 1f, 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.ORANGE); //border color
// 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);
}
});
}
}
2. TestNotificationPopUp.java

public class TestNotificationPopUp extends javax.swing.JFrame {
public TestNotificationPopUp() {
initComponents();
}
// //GEN-BEGIN:initComponents

jPanel2 = new javax.swing.JPanel();
jButton5 = new javax.swing.JButton();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Antenna");
jPanel2.setBorder(javax.swing.BorderFactory.createTitledBorder(" System "));
jButton5.setText("Open Notification");
jButton5.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jButton5ActionPerformed(evt);
}
});
org.jdesktop.layout.GroupLayout jPanel2Layout = new org.jdesktop.layout.GroupLayout(jPanel2);
jPanel2.setLayout(jPanel2Layout);
jPanel2Layout.setHorizontalGroup(
jPanel2Layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)
.add(org.jdesktop.layout.GroupLayout.TRAILING, jPanel2Layout.createSequentialGroup()
.add(182, 182, 182)
.add(jButton5)
.add(256, 256, 256))
);
jPanel2Layout.setVerticalGroup(
jPanel2Layout.createParallelGroup(org.jdesktop.layout.GroupLayout.LEADING)

getContentPane().setLayout(layout);

pack();
