Move JLabel in GridLayout java swing - java

I'm trying to move a Robot represented by a JLabel into a GridLayout.
The move is made but the display of the JLabel is only done for the final finishing square.
I would like to see the move from box to box. How can I do ?

setIcon(imageRobot);

public void seDeplacer (JPanel panel, Vector<Case> listeDeCases) {
for (int i=0; i<5; i++) {
LayoutManager layout = panel.getLayout();
try { Thread.sleep(1000);
panel.remove(panel.getComponent(i));
panel.add(this, i);

public void detruire () {

try { Thread.sleep(1000);
Don't do this on the AWT Event Dispatch Thread (EDT). Your GUI can't be repainted because this code is blocking it.
Use javax.swing.Timer (not to be confused with any other Timer) to set an event for the next time robot needs to be moved. You will need to keep track of state outside of local variables.

Here's a working solution which you can tailor to your use. The cause seemed to be the way you had tried to display the Components rather than the code in your action listener.
Your approach was just replacing myText with myPic when you initially set up the JFrame. Instead you need to use a layout manager. The example I've given is with overlaying using JLayeredPane. You may wish to use a layout manager instead if this is not the desired outcome, see the Oracle Tutorial on using layout managers.
Widget class
package widget;
import java.awt.Shape;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.geom.Ellipse2D;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JLayeredPane;
import javax.swing.SwingUtilities;
import javax.swing.Timer;
public class Widget extends JFrame {
private static final int UPDATE_TICK = 5_000;
private static final int WIDGET_WIDTH = 150;
private static final int WIDGET_HEIGHT = 150;
private JLabel myText = new JLabel();
private JLabel myPic = new JLabel();
private Weather weather = new Weather();
private Timer simpleTimer;
public void createAndShow() {
setUndecorated(true);
setSize(WIDGET_WIDTH, WIDGET_HEIGHT);
Shape shape = new Ellipse2D.Float(0, 0, WIDGET_WIDTH, WIDGET_HEIGHT);
// AWTUtilities.setWindowShape(this, shape);
setShape(shape); // do this instead
myText.setHorizontalAlignment(JLabel.CENTER);
myPic.setHorizontalAlignment(JLabel.CENTER);
JLayeredPane layered = new JLayeredPane();
myText.setBounds(0, 0, WIDGET_WIDTH, WIDGET_HEIGHT);
myPic.setBounds(0, 0, WIDGET_WIDTH, WIDGET_HEIGHT);
layered.add(myPic, 1, 0);
layered.add(myText, 2, 0);
add(layered);
simpleTimer = new Timer(UPDATE_TICK, new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
update();
}
});
update();
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
simpleTimer.start();
}
private void update() {
myText.setText(weather.getTemp());
myPic.setIcon(new ImageIcon(weather.getImage(WIDGET_WIDTH, WIDGET_HEIGHT)));
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
Widget w = new Widget();
w.createAndShow();;
}
});
}
}
Weather class for demonstration purposes
package widget;
import java.awt.Color;
import java.awt.image.BufferedImage;
import java.util.Random;
public class Weather {
private static final Random rand = new Random();
private static final Color[] randColors = {Color.YELLOW,
Color.GREEN,
Color.WHITE};
public String getTemp() {
return Integer.toString(rand.nextInt(100));
}
public BufferedImage getImage(int width, int height) {
int colorIndex = rand.nextInt(randColors.length);
BufferedImage img = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
for (int x = 0; x < img.getWidth(); x++) {
for (int y = 0; y < img.getHeight(); y++) {
img.setRGB(x, y, randColors[colorIndex].getRGB());
}
}
return img;
}
}

Reminder using JOptionPane

I am designing one reminder type application using java swing.
In this I am giving two options to user, using JOptionPane YES_NO_OPTION. But what i want is if user not given any input within 10 minutes it should choose YES as default option.
what i have to do for that?
Please check below code...
public void snooze()
{
int action = JOptionPane.showConfirmDialog(null, "Yes = close citrix and Aventail \n No = snooze after 30min", "Close", JOptionPane.YES_NO_OPTION);
if(action == 0){
killcitrix();
endaventail();
}
else{
JOptionPane.showMessageDialog(null, "Will snooze after 30min");
try {
TimeUnit.SECONDS.sleep(30);
} catch (InterruptedException e2) {
// TODO Auto-generated catch block
e2.printStackTrace();
}
snooze();
}
}

As user1803551 already mentioned, use a Timer. Here is an example:
after 10 seconds of inactivity (if the user didn't press any button), the dialog will automatically dispose and the selected option will be JOptionPane.YES_OPTION
If the user pressed 'No', a new JOptionPane with the same functionalities will appear after 5 seconds.

Message box without any buttons at all

I want to create auto-disposing message dialog. Everything works beside that there is still an ok button to click.
I want to get read the button.
Please check out this code -> works perfectly:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.SwingUtilities;
import javax.swing.Timer;
public class CloseOptionPane {
#SuppressWarnings("serial")
private static void createAndShowGui() {
final JLabel label = new JLabel();
int timerDelay = 1000;
new Timer(timerDelay, new ActionListener() {
int timeLeft = 3;
#Override
public void actionPerformed(ActionEvent e) {
if(timeLeft > 0) {
label.setText("Human player. It is your move!");
timeLeft--;
} else {
((Timer) e.getSource()).stop();
Window win = SwingUtilities.getWindowAncestor(label);
win.setVisible(false);
}
}
}) {
{
setInitialDelay(0);
}
}.start();
JOptionPane.showMessageDialog(null, label);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
