Using a FileChooser to get and display an image

[Alison Davis]

Hi everyone,

Basically, I'm trying to add this code to an 'open image' button. I'd like it to display the image in a JFrame, and I think I've got most of it sorted, but there's obviously something that I'm missing. If anyone can point it out, it'd be fantastic!

    JFileChooser fc = new JFileChooser();
    fc.setDialogTitle ("Choose Image..");
    
    FileNameExtensionFilter filter = 
            new FileNameExtensionFilter("JPG Images", "jpg");
    fc.setFileFilter(filter);    
    int returnVal = fc.showDialog(MosaicUI.this, "Choose..");
    File file = null;
            
    if (returnVal == JFileChooser.APPROVE_OPTION)
        file = fc.getSelectedFile();
        Image image = null;
        
    try 
    {
        image = ImageIO.read(file);      
    } catch (IOException e) {}
              
    JFrame frame = new JFrame("Preview image");
    JPanel panel = new JPanel();
    ImageIcon image2 = new ImageIcon ("image.jpg");        
    panel.add(new JLabel(image2)); 

    frame.getContentPane().add(panel);
    frame.setSize(500, 500);
    frame.setVisible(true);

What makes you think you are missing something?

I notice that you ask the user to select a file, then you make that file into an image (ignoring any exceptions which might be thrown), then you don't do anything with the image. Was that the something you were missing, or were there some other symptoms you could tell us about?

Welcome to JavaRanch

Please use the CODE button; I shall try to edit your post (since you are new) so you can see how much better it looks.

Thankyou - yes, I was missing the fact that I wasn't actually doing anything with the image! Silly me.

Didn't notice the code option, duly noted, and thanks again : )
