I just want to change the system tray Icon image for my application. I did 2 things -
Just changed the URL in the default program -
final TrayIcon trayIcon = new TrayIcon(createImage("images/Graph.png", "tray icon"));
Second try -
Image img = Toolkit.getDefaultToolkit().getImage("images/Graph.png");
final TrayIcon trayIcon = new TrayIcon(img, "Application Name", popup);
The application launches in both cases but no image is shown. Its a blank placeholder. What am i doing wrong ?
images/Graph.png
is not a valid URL for an image located in your jar. Hence, I guess that img
is null on your second try.
I suggest you this way :
//Get the URL with method class.getResource("/path/to/image.png")
URL url = System.class.getResource("/images/Graph.png");
//Use it to get the image
Image img = Toolkit.getDefaultToolkit().getImage(url);
final TrayIcon trayIcon = new TrayIcon(img, "Application Name", popup);
You shall also ensure that images/
is in your classpath.
