Probleme d'affichage en java

Salut Bernard!

Jem suis penché sur ton problème et je suis arrivé à la solution ci-dessous.

J'ai créé 3 classes:
- JIconableTextArea qui permet de dessiner des ImageIcon sur un TextArea
- ChatMessage qui est une structure de données permettant de stocker une icône, un nickname et un message
- Tester qui est juste une classe éténdant JFrame qui permet de tester l'application

Tu trouveras le code des ces classes ci-dessous.
A toi de l'adapter afin que cela réponde exactement à ce que tu attends.

package temp;

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;

public class JIconableTextArea extends JTextArea {
private ArrayList chatData;

public JIconableTextArea() {
super();
initialize();
}

public JIconableTextArea(int rows, int cols) {
super(rows, cols);
initialize();
}

public void addMessage(ChatMessage chatMessage) {
chatData.add(chatMessage);
}

public void paint(Graphics g) {
g.clearRect(0, 0, this.getWidth(), this.getHeight());
Iterator it = chatData.iterator();
ImageIcon icon;
String nickname;
String message;
for(int i = 0; i < chatData.size(); i++) {
ChatMessage chatMessage = (ChatMessage)chatData.get(i);
icon = chatMessage.getIcon();
nickname = chatMessage.getNickname();
message = chatMessage.getMessage();
int w = icon.getIconWidth();
int h = icon.getIconHeight();
icon.paintIcon(this, g, 0, h * i);
g.drawString(nickname + " dit: " + message, w + 10, h * i + h / 2 + getFont().getSize() / 2);
}
}

private void initialize() {
chatData = new ArrayList();
chatData.add(new ChatMessage(new ImageIcon("D:/test.jpg"), "Jean", "Salut! Comment vas-tu?"));
chatData.add(new ChatMessage(new ImageIcon("D:/test2.jpg"), "Anne", "Bien merci et toi?"));
chatData.add(new ChatMessage(new ImageIcon("D:/test.jpg"), "Jean", "Un peu fatigué!"));
}
}

textarea.repaint();

});
c.add(jsp);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
}

public static void main(String[] args) {
Tester tester = new Tester();
}
}
