How do I add an image to a JButton

Question

I am trying to add an image to a JButton and I'm not sure what I'm missing. When I run the following code the button looks exactly the same as if I had created it without any image attribute. Water.bmp is in the root of my project folder.

ImageIcon water = new ImageIcon("water.bmp");     JButton button = new JButton(water);     frame.add(button); 

Answer 1

I think that your problem is in the location of the image. You shall place it in your source, and then use it like this:

  JButton button = new JButton();   try {     Image img = ImageIO.read(getClass().getResource("resources/water.bmp"));     button.setIcon(new ImageIcon(img));   } catch (Exception ex) {     System.out.println(ex);   } 

In this example, it is assumed that image is in src/resources/ folder.

@Rogach

and you may like to add:

// to remote the spacing between the image and button's borders button.setMargin(new Insets(0, 0, 0, 0)); // to add a different background button.setBackground( ... ); // to remove the border button.setBorder(null);
