Question

i having problem with draw image in applet. i want to display all images one by one in applet but it shows only last image of the folder my code is given below.

public class ImageInSwingTest extends JApplet
{
    String filePath="C:\\Users\\yogi\\Pictures\\pictures"; //all .png files more than 200 files
    String files;
    File folder=new File(filePath);
    File[] listOfFiles;
    Image m;

    @Override
    public void init()
    {
        listOfFiles=folder.listFiles();
        for(int i=0;i<listOfFiles.length;i++)
        {
            if(listOfFiles[i].isFile())
            {
                files=listOfFiles[i].getName();
                if(files.endsWith(".png"))
                {
                    String filepath=listOfFiles[i].getAbsolutePath();
                    System.out.println(filepath);
                    try {
                         m = ImageIO.read(new File(filepath));
                        paint(ImageInSwingTest.this.getGraphics());

                    } catch (IOException ex) {
                        Logger.getLogger(ImageInSwingTest.class.getName()).log(Level.SEVERE, null, ex);
                    }
                }
            }

        }
    }
    public void paint(Graphics g)
    {
        g.drawImage(m, 0, 0, this);

    }

}

so, please can any one tell me how can i display all images one by one.?
Thanks.

• because each of loop inside for(int i=0;i<listOfFiles.length;i++) replacing JApplet‘s contents

• put JPanel to the JApplet

• put Images to the array of Icon[]

• put Icon to the JLabel

• use GridLayout for placing JLabel with Icons to the JPanel

• don’t paint to the JApplet directly, use JPanel or JComponent with override method paintComponent() instead of paint()

EDIT

actually i want all images to replace each other so all images are look like playing movie

• you have to pause this process by Thread.sleep(int);

• you can use Thread.sleep(int); inside SwingWorker or Runnable#Thread,

• don’t use Thread.sleep(int); other ways in the Swing GUI, because to block Event Dispatch Thread, and is possible that nothing will be painted or only the last image too

• Runnable#Thread would be better and easiest, but any output from Runnable#Thread to the Swing GUI you have to wrap JLabel.setIcon(myIcon) to the invokeLater
