Android like Toast in Swing

Question

I am trying to develop a Toast (Android) like feature in my Swing application. As a standalone, its working perfectly. But when integrated into the application, its posing problems.

LOOKS GOOD // If the window is resized, the shape is recalculated here. @Override public void componentResized(ComponentEvent e) { setShape(new RoundRectangle2D.Double(0,0,getWidth(),getHeight(),50,50)); } }); setUndecorated(true); setSize(300,100); setLocati…

Try this code for toast:

```
public class Test extends JFrame {

private JPanel contentPane;

public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    Test frame = new Test();
                    frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

public Test() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        contentPane.setLayout(new BorderLayout(0, 0));
        setContentPane(contentPane);

JButton btnTestToast = new JButton("Test Toast");
        btnTestToast.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                ToastMessage toastMessage = new ToastMessage("Sample text to toast ",3000);
                toastMessage.setVisible(true);
            }
        });
        contentPane.add(btnTestToast, BorderLayout.SOUTH);
    }

}

public class ToastMessage extends JDialog {
    int miliseconds;
    public ToastMessage(String toastString, int time) {
        this.miliseconds = time;
        setUndecorated(true);
        getContentPane().setLayout(new BorderLayout(0, 0));

JPanel panel = new JPanel();
        panel.setBackground(Color.GRAY);
        panel.setBorder(new LineBorder(Color.LIGHT_GRAY, 2));
        getContentPane().add(panel, BorderLayout.CENTER);

JLabel toastLabel = new JLabel("");
        toastLabel.setText(toastString);
        toastLabel.setFont(new Font("Dialog", Font.BOLD, 12));
        toastLabel.setForeground(Color.WHITE);

setBounds(100, 100, toastLabel.getPreferredSize().width+20, 31);

setAlwaysOnTop(true);
        Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
        int y = dim.height/2-getSize().height/2;
        int half = y/2;
        setLocation(dim.width/2-getSize().width/2, y+half);
        panel.add(toastLabel);
        setVisible(false);

new Thread(){
            public void run() {
                try {
                    Thread.sleep(miliseconds);
                    dispose();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }.start();
    }
}
```
