images in JList

[Nesrin aboud]

Hi there,

I made an applet and added a JList object into it and I have a folder containing images (0.jpg, 1.jpg, 2.jpg)

I want to add these images in the JList object in the form of loop when I tries this

  

BufferedImage[] images;

	private void loadImages() {
		String picFolder = System.getProperty("user.home")
				+ System.getProperty("file.separator")  + "/";
		File file = new File(picFolder);
		String[] fileNames = new String[getFilesCount(file)];
				images = new BufferedImage[fileNames.length];
		for (int i = 0; i < images.length; i++) {
			try {
				String path = picFolder + i + ".jpg";
				System.out.println(path);
				images[i] = ImageIO.read(new File(path));
			} catch (MalformedURLException mue) {
				System.out.println("url: " + mue.getMessage());
			} catch (IOException ioe) {
				System.out.println("read: " + ioe.getMessage());
			}
		}
		ImagesList.setListData(images);
	}


  

 

/**
	 * get the scanned and saved image count
	 */
	public int getFilesCount(File file) {
		File[] files = file.listFiles();
		if (!file.isDirectory()) {
			return 1;
		}
		int count = 0;
		if (files != null) {
			for (File f : files) {
				count += getFilesCount(f);
			}
		}
		System.out.println("----> " + count);
		return count;
	}

   

the list resulted in list of object reference not image itself
so is there any solution for this issue

and thank you very much

Add ImageIcon's to the ListModel, not Image's.

[Nesrin aboud]

so how can I select from the ListModel certain icon to get the image and save it to folder or database

"nesrin ab", please check your private messages for an important administrative matter.

[Rob Camick]

Read the ImageIcon API.

I tried another solution but also failed
please if any one can help me

   

	private JList imagesList=new JList();


private void loadImagesList() {
		String picFolder1 = System.getProperty("user.home")
				+ System.getProperty("file.separator") + "apis" + "/";
		File file = new File(picFolder1);
		int scannedImagesNum = getFilesCount(file);
		icons= new ImageIcons[scannedImagesNum];
		System.out.println("scannedImagesNum = "+scannedImagesNum);
		System.out.println(picFolder1);
		for (int i = 0; i < scannedImagesNum; i++) {
			String path = picFolder1 + i + ".jpg";
			System.out.println("path= "+path);
			icons[i] = new ImageIcons("",path);
		}
		 ImagesList.setListData(icons);
 ImagesList.setCellRenderer(new IconsRenderer());
	}

public class ImageIcons {
	  private  String title;

	  private  String imagePath;

	  private ImageIcon image;
	  public ImageIcons() {
		  }

	  public ImageIcons(String title, String imagePath) {
	    this.title = title;
	    this.imagePath = imagePath;
	  }

	  public String getTitle() {
	    return title;
	  }

	  public ImageIcon getImage() {
	    if (image == null) {
	      image = new ImageIcon(imagePath);
	    }
	    return image;
	  }

	  // Override standard toString method to give a useful result
	  public String toString() {
	    return title;
	  }
}


public class IconsRenderer extends JLabel implements ListCellRenderer {
	private static final Color HIGHLIGHT_COLOR = new Color(0, 0, 128);

	  public IconsRenderer() {
	    setOpaque(true);
	    setIconTextGap(12);
	  }

	public Component getListCellRendererComponent(JList list, Object value,
		      int index, boolean isSelected, boolean cellHasFocus) {
		ImageIcons icon = (ImageIcons) value;
	    setText(icon.getTitle());
	    setIcon(icon.getImage());
	    if (isSelected) {
	      setBackground(HIGHLIGHT_COLOR);
	      setForeground(Color.white);
	    } else {
	      setBackground(Color.white);
	      setForeground(Color.black);
	    }
	    return this;
	  }
}

in the last one there is no exception thrown but the images do not appear in the list

[Rob Camick]

I tried another solution but also failed

Why? I already gave you the solution.

[Nesrin aboud]

can you give a sample code,
I tried your solution, but I have no experience with applets and failed to do it
so if you can write the sequence that is should follow to use the ListModel and ImagIcon

[Michael Dunn]

> I made an applet
> images[i] = ImageIO.read(new File(path));

won't work in applets

google
getCodeBase()

[Nesrin aboud]

why Michael
and where to add the getCodeBase()

[Rob Camick]

but I have no experience with applets

Well, thats an important piece of information to leave out (that this is for an applet).

Read the section from the Swing tutorial on How to Make Applets for an example of using images in an applet.

Thank you all very much.
