setImageIcon doesn't set JFrame icon on mac swing window

Question

I've already tried loads of code from Stack. For some reason it's just not setting the ImageIcon for my JFrame, the comments are other attempts that have not worked;I avoided calling super so that I could reference the JFrame -- GUIPhotoAlbum extends JFrame; code:

public GUIPhotoAlbum ()
{
    super("PhotoAlbum");
    ImageIcon img = new ImageIcon("Photos/albumIcon.png");
    this.setIconImage(img.getImage());

    /*
    try{
        setIconImage(ImageIO.read(new File("Photos/albumIcon.png")));
    }catch(Exception e){
        System.out.print("Didn't work.");
    }
    */

    setSize(875, 625);
    this.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
    this.setLayout(new BorderLayout(5, 5));

    initComponents();
    initMenuBar();

    initTopPanel();
    add(topPanel, BorderLayout.CENTER);

    initBottomPanel();
    add(bottomPanel, BorderLayout.SOUTH);

    addListeners();

    setLocationRelativeTo(null);
    setVisible(true);
}

EDIT I'm running the program like this, where I try to set the ImageIcon of JFrame in the GUIPhotoAlbum() constructor; here's the driver:

public class AlbumDriver
{   
    public static void main (String [ ] args)
    {
           SwingUtilities.invokeLater 
           (
                 new Runnable()
                 {
                        @Override
                        public void run()
                        {
                            GUIPhotoAlbum pa = new GUIPhotoAlbum();
                        }   
                 }
           ); 
    }

}

What am I doing wrong here? PS I've tried BufferedImage, ImageIcon, using File.. and I'm using a Mac

Where is `Photos/albumIcon.png` located is it within the application Jar or one the file system? — MadProgrammer, Apr 30 '14 at 01:27
I guess the file system? It's just a subfolder of the project.. `Photos` that is — Chizx, Apr 30 '14 at 01:27
Start by using `ImageIO.read(new File("Photos/albumIcon.png"))`, this will throw an `IOException` if the file can't be loaded for some reason. Make sure that the program is been executed in the same directory as the `Photos` directory — MadProgrammer, Apr 30 '14 at 01:29
The exception is never thrown.. let me make an edit real quick to explain how I'm running this, also I've just been thinking the whole time that perhaps the mac-java window doesn't display it for some reason but I don't think this is the case — Chizx, Apr 30 '14 at 01:31

Mac does not support frame icons, as seen in this answer.

Thank you, I had figured and just turned in my project anyways, I'm sure my code would show up on windows, though I did not test it. – Chizx May 01 '14 at 01:47
I get the same result. – trashgod Aug 10 '21 at 17:13

Use this to change Dock Image in mac:

File imageFile = new File("Your image Path");
Image image =  ImageIO.read(imageFile);
Application.getApplication().setDockIconImage(image);

For windows use this:

YourFrameObject.setIconImage(image);

The problem is, you class appears to be extending from JFrame but you're creating a new instance of a JFrame and setting it's icon instead...

JFrame newFrame = new JFrame("PhotoAlbum");

ImageIcon img = new ImageIcon("Photos/albumIcon.png");
newFrame.setIconImage(img.getImage());

Don't create the second instance of the JFrame, there's no need for newFrame in this instance...

For example...

public GUIPhotoAlbum ()
{
    super("PhotoAlbum");
    ImageIcon img = new ImageIcon("Photos/albumIcon.png");
    setIconImage(img.getImage());

    /*
       //when uncommented, exception is never thrown
    try{
        setIconImage(ImageIO.read(new File("Photos/albumIcon.png")));
    }catch(Exception e){
        System.out.print("Didn't work.");
    }
    */

    // Hint use pack instead, but only after
    // You've finished adding the components to the frame
    setSize(875, 625);
    setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
    setLayout(new BorderLayout(5, 5));

    initComponents();
    initMenuBar();

    initTopPanel();
    add(topPanel, BorderLayout.CENTER);

    initBottomPanel();
    add(bottomPanel, BorderLayout.SOUTH);

    addListeners();

    setLocationRelativeTo(null);
    setVisible(true);
}

Ah.. I see, I also tried setting it to "pa" in the driver, that didn't work either — Chizx, Apr 30 '14 at 01:40
Sorry pa is the name of the new GUIPhotoAlbum in the driver class' main method. I was just setting this up to and it didn't work... I'll update top code.. Yeah this is what I was trying earlier before incorrectly trying to create the new JFrame. This isn't working either, and `pack()` messes up the program because I have an empty JPanel on the bottom that gets populated with Photos — Chizx, Apr 30 '14 at 01:44
I think the problem is that it's mac, I haven't tried running this on Windows but I think it would work on windows. — Chizx, Apr 30 '14 at 01:53
I'm pretty sure that you can set the icon of a mac window...or least it worked last time I bothered to try — MadProgrammer, Apr 30 '14 at 01:54
