Is there a way to Change the JOptionPane layout, like the color at the top and the image at the top left?

Question

I am curious, I am wondering if there exist a way to make the top of the JOptionPane into a different color, say red or orange. Also i was wondering how to change the image

Answer 1

There are three options here:

1. Use one of the predefined icons using the respective message type:
   JOptionPane.showMessageDialog(frame, "Eggs are not supposed to be green.", "Inane error", JOptionPane.ERROR_MESSAGE);

2. Use a custom icon:
   JOptionPane.showMessageDialog(frame, "Eggs are not supposed to be green.", "Inane custom dialog", JOptionPane.INFORMATION_MESSAGE, icon);

3. Use a look & feel to have consistent icons all over your application: How to Set the Look and Feel

Have a look at this page of the Java Tutorial for more information on dialogs.
