how to change the ImageIcon of a JLabel?

[Kay Tracid]

Hi,
I have a JLabel with an icon that is shown fine. Only if i try to change the icon, i get no effect. Can you help, please?

  
  private ImageIcon imgIcon = new ImageIcon("icon/newPic.gif");
  private JLabel l1 = new JLabel(imgIcon);
  public void setImage(Image img)
  {
    System.out.println(img.getHeight(null)+ " " + img.getWidth(null));
// first way
    imgIcon.setImage(img);
//second way
    l1.setIcon(new ImageIcon("icon/changePic.gif"));
    revalidate();
    repaint();
  }

hi,
try to change the icon inside SwingUtilities.invokeLater() (see the API for more information.)
All Code that changes the graphic inside a GUI has to be called from the Swing thread. To be sure of that always change the gui inside SwingUtilities.invokeLater().
