jtable imageicon

> nothing appears and there is no exception caught.

hint: check ImageIcon size.

> is no exception caught.

ImageIcon constructor does not throw exceptions. if you want better control, you have to download the image data yourself

I checked the size, still there is no image viewable.

The URL is http://www.triviaplanet.com/study%20guide/maths_tips/quick-maths-pic.jpg

I tried another URL http://www.bbc.co.uk/education/asguru/generalstudies/maths/images/maths.gif

Still it didnt work. I did all the necessary steps, I did the getColumnClass method and everything else. It worked when I use a picture stored in my pc. If I tried to load a picture from the internet It wont work.

After that I tried to check the image height and width, it shows -1 and -1 respectively on the console.

if the size of the imageicon is too large, how do I make it viewable to the user? e.g. providing scrolling within a cell? Is it possible to resize the image?

> I checked the size, still there is no image viewable.

so was the size greater than 1 x 1 ?

the size was -1, -1
see the comment above

> the size was -1, -1

that means that you are using WRONG URL

> data[][] = .....new ImageIcon(new URL("http://......"))....

check the URL

use System.out.println() to print it in the console and try it inside your browser

yes, I checked the URL.
I actually copied and pasted the URL from the browser to the codes.
Something must be wrong, but I dont know what.
Please help

is the applet loaded from the same host ?

its an application not an applet

post the full code (small compilable example that reproduces the problem)

its an application not an applet

//this Object[][] is created in another class
final Object data[][] = {{new String("http://www.bbc.co.uk/education/asguru/generalstudies/maths/images/maths.gif")}};

//im going to pass the object created above into this contructor
contructor(final Object[][] data){
this.data = data;
convertToImage(this.data);
TableModel tm = ......
JTable table = new JTable(tm);
.
.
.
.
}

public void convertToImage(Object[][] data){
  String temp = data[0][0] ;
  ImageIcon ic = new ImageIcon(new URL(temp));
  data[0][0] = new ImageIcon(ic.getImage());
}



//the end

What I am trying to do is to get an Object[][] from another class. This Object[][] will contain the values needed in the table except for one column. One of the objects in the Object[][] is a string that contains the web addy of the picture. I need to convert this string to an ImageIcon and initiate the JTable with this using a TableModel

I said

> small compilable example that reproduces the problem

ok try this...
import java.net.*;
import javax.swing.*;

public class testing{
  public testing(){
    //compilable, but will take awhile to load and the size is -1,-1;
    ImageIcon ic = new ImageIcon(new URL("http://www.bbc.co.uk/education/asguru/generalstudies/maths/images/maths.gif");
    System.out.println("?"+ic.getIconHeight()+"?"+ic.getIconWidth());
  }
}

code posted below produces the following output

height: 168, width: 175

so there is nothing wrong with it.


what's next ?

********** code ************

import java.net.*;
import javax.swing.*;

public class testing
{
 public static void main(String args[])
 {
   try
   {
     //compilable, but will take awhile to load and the size is -1,-1;
     ImageIcon ic = new ImageIcon(new URL("http://www.bbc.co.uk/education/asguru/generalstudies/maths/images/maths.gif"));
     System.out.println("?"+ic.getIconHeight()+"?"+ic.getIconWidth());
   } catch (Throwable x)
   {
     x.printStackTrace();
   }
 }
}

i tried the same, but mine shows -1,-1

so whats wrong with it?

the only possible explanation is that you are begind a proxy. does you browser use proxy ?

if yes - you have to configure your application to use that proxy. add the following code inside your main method

System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyHost", "127.0.0.1");
System.getProperties().put("proxyPort", "81");

my browser uses a proxy, but I still cant get it working even though I tried your code...

>System.getProperties().put("proxySet", "true");
>System.getProperties().put("proxyHost", "127.0.0.1");
>System.getProperties().put("proxyPort", "81");

so whats wrong with it?

did you change the IP and port for your proxy ?

nono, i didnt do anything. btw, how do i get the ip dynamically during runtime?

how does this thing work?
lets say I do not know whether the client is using proxy, then how should I write my code?
