opdatere JLabel

hov det er lblImg der skal ændres.
Den der setBrick bruger jeg ikke endnu... lige nu skal billede bare skifte når man trykker med musen (så kommer resten senere ;))

Kan du poste et eksempel med problemet som man kan koere?

Hvis ikke er mit bedste bud at du skal proeve at kalde repaint efter at have opdateret icon.

Den her kan godt køre :


package connectfour;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.*;
import java.awt.*;
import javax.swing.border.*;

public class ConnectFourGUI extends JFrame {
 
  static JLabel[][] board;
  ImageIcon redPieceSat = new ImageIcon("Images/redPieceSat.png");
  ImageIcon bluePiece = new ImageIcon("Images/bluePieceSat.png");
  ImageIcon noBricks = new ImageIcon("Images/noBricks.png");
  ImageIcon player1Img = new ImageIcon("Images/red.png");
  ImageIcon player2Img  = new ImageIcon("Images/blue.png");
  ImageIcon playerImg;
  JLabel lblImg = new JLabel();
  static int CurrentPlayer=2;
 
 
 
 
  public ConnectFourGUI(){
 
  JPanel BoardPanel = new JPanel(new GridLayout(6,7));
  BoardPanel.setBorder(new LineBorder(Color.BLACK));
             
  JLabel[][] board = new JLabel[6][7];
   
    for (int r=0;r<6;r++){
        for (int c=0;c<7;c++){
        board[r][c] = new JLabel(noBricks);
        board[r][c].setBorder(new LineBorder(Color.BLACK));
        board[r][c].setBackground(Color.YELLOW);
        BoardPanel.add(board[r][c]);
        board[r][c].addMouseListener(new listener());
    }
    }
   
  JPanel TurnPanel = new JPanel();
  JLabel lblTurn;
  Font font = new Font("Verdana", Font.BOLD, 25);
  JLabel lblTurnTxt = new JLabel("Your turn player: ");
  lblTurnTxt.setFont(font);
  showPlayer();
  // lblImg = new JLabel(showPlayer());
  TurnPanel.add(lblTurnTxt);
  TurnPanel.add(lblImg);
 
  setLayout(new BorderLayout());
  add(TurnPanel, BorderLayout.NORTH);
  add(BoardPanel, BorderLayout.CENTER);
  }
 
  public int getCurrentPlayer(){
    return CurrentPlayer;   
    }
 
  public static void main(String[] args) {
  // GameLogic game = new GameLogic();
  ConnectFourGUI frame = new ConnectFourGUI();
  frame.setTitle("Connect 4");
  frame.pack();
  frame.setLocationRelativeTo(null);
  frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
  frame.setVisible(true);
  frame.setResizable(false);
    }
 
 
  private void showPlayer(){
    int player = getCurrentPlayer();
      System.out.println("show fanger" +player);
      System.out.println(lblImg.toString());
   
    if (player==1){
        lblImg.setIcon(new ImageIcon("Images/red.png")); 
    }
    else{
        lblImg.setIcon(new ImageIcon("Images/blue.png"));
    }   
  repaint();
  }

    public void exitGame(){
  }
   
    public void nextPlayer(){
    CurrentPlayer = (getCurrentPlayer()%2)+1;
        System.out.println("Næste spiller er:" + CurrentPlayer);
        showPlayer();
    }

 
    public void setBrick(int column, int row) {
       
    if (CurrentPlayer==1){
        System.out.println("her");
        System.out.println(row);
        System.out.println(column);
        //board[column][row]= (new JLabel("ok"));
                //.setIcon(new ImageIcon("Images/bluePieceSat.png"));
       
    }
    else {
        System.out.println("eller her");
        //board[column][row].setIcon(redBrick);
    }
    //currentPlayer = (currentPlayer%2)+1;
  }   
}


class listener implements MouseListener{
     
  ConnectFourGUI gui;
  ConnectFour game;
 
  public void mouseClicked(MouseEvent e) {
            ConnectFourGUI gui = new ConnectFourGUI();
            gui.nextPlayer();
            gui.setBrick(4,2);
           
        }

        public void mousePressed(MouseEvent e) {
        }

        public void mouseReleased(MouseEvent e) {
        }

        public void mouseEntered(MouseEvent e) {
        }

        public void mouseExited(MouseEvent e) {
        }     
}

   
Den opretter bare en spille plade og sætter det billede, der svarer til spiller 1 på... men den opdaterer ikke når man trykker med musen

Er der slet ingen der har nogen ideer??

repaint();

er ikke engang noedvendig - du skal bare kalde nextPlayer paa det rigtige GUI objekt.

board[r][c].addMouseListener(new listener(this));

og:

class listener implements MouseListener{
   
  ConnectFourGUI gui;
  ConnectFour game;

  listener(ConnectFourGUI gui) {
      this.gui = gui;
  }
  public void mouseClicked(MouseEvent e) {
            //ConnectFourGUI gui = new ConnectFourGUI();
            gui.nextPlayer();
            gui.setBrick(4,2);
         
        }

ok?
