JButton background in SWING

[Adriano Bellavita]

Hi all,

I have to customize JButton in my application.

Default gray button is not what I want...

I have downloaded an image from internet and I want to put this image as background for my component.

I have try in paint method, by using ImageIcon, but I have 2 problems:

Image is not a background, but it is placed to the left of the button

Image is not resizable.

I simply want that the image become the background of the button, and that the text of the button is placed over the image. (As a simple "EXIT" button)

How can I do that?

Adriano, you are partly on the right track, by using an ImageIcon object made from your image. But you don't need to do anything in your Paint method. Read the JButton methods documentation. You will find one that lets you assign your ImageIcon to the JButton, doing most of what you want. Your JButton's text will not (at least not easily) appear over the image, but a simple workaround would be to put the text into the image itself.

If you can't get that to work, try posting enough of your code so people here can help you with it.

No need for that. Just setHorizontal/VerticalTextPosition appropriately.

There's tutorial linked from the API for JButton wehre you can find the answers to all this and more.

edit Except tha part about a resizable image. For that you may need to write your own Icon implementation, and ensure that the layout takes care of determining the size of the button.

Ah, right you are:

        jButton1.setIcon(new javax.swing.ImageIcon(getClass().getResource("/buttonimage/BulbLogo.png")));
        jButton1.setText("Lights!");
        jButton1.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);

Thanks!
