Change Java application icon?

Question

Does anyone know how to change the default java application app icon? I am using a mac if it makes a difference. Any ideas are good!

Answer 1

You can use JFrame.setIconImage .

Here is an example .

Haven't seen any issues on the mac.

Answer 2

import javax.swing.JFrame;
import javax.swing.ImageIcon;

class JFrameTest
{
    public static void main(String _[])
    {
        JFrame jFrame = new JFrame("Hello World!!");
        jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jFrame.setIconImage(new ImageIcon("c:/home/ravi/creampink.png").getImage());
        jFrame.setSize(400,400);
        jFrame.setVisible(true);
    }
}

Answer 3

The JFrame.setIconImage is where you want to work. It seems to be working on all operating systems.

Answer 4

Place the icon in your resources folder ( src/main/resources for a Maven project with default settings, or alongside the main window class file for an Eclipse project with default settings). (The accepted example uses a hard-coded path in the file system—that is OK in a lab setting, but will break on deployment.)

Assuming theWindow is the main window of your application, do the following:

theWindow.setIconImage(Toolkit.getDefaultToolkit().getImage(
    ClassLoader.getSystemResource("someicon.png")));

If you are subclassing JFrame , you can do this in the constructor (in that case, drop the theWindow. prefix).
