jbutton background image

[Cathy Song]

Hi All,

This code adds an image on top of jbutton:
Icon icon = new ImageIcon ("oval.png");
JButton back = new JButton(icon);

How can I change the size of the button so that it fits the image size.
Basically I am trying to create an oval button.

Thanks,
Cathy.

Usually a JButton should show up at the correct size to show all the image when you instantiate it with the ImageIcon. If you change the icon later you may have to call 'revalidate' on the button or its parent container. If the button is in a Container whose layout manager respects the preferred size of its components, eg, FlowLayout, GridBagLayout, this should work

    back.setPreferredSize(new Dimension(newWidth, newHeight));

You can use 'setBounds' if you need to get heavy-handed.

use setPreferredSize(new Dimension(width, height))

Thanks Craig and Mahesh - that solution worked
