Java: using an image as a button

问题

I would like to use an image as a button in Java, and I tried to do this:

BufferedImage buttonIcon = ImageIO.read(new File(\"buttonIconPath\"));
button = new JButton(new ImageIcon(buttonIcon));

But this still shows the actual button behind the image, I would only like the image to function as the button, how can I do this?

回答1:

Remove the border like so:

button.setBorder(BorderFactory.createEmptyBorder());

and then also the contents¹:

button.setContentAreaFilled(false);

_{¹: Taken from the solution added to the question by @3sdmx}

回答2:

A suggestion would be to set the Image as a label and add a mouse listener to the label to detect clicks.

Example:

ImageIcon icon = ...;

JLabel button = new JLabel(icon);

button.addMouseListener(new MouseAdapter() {
  @Override
  public void mouseClicked(MouseEvent e) {
     ... handle the click ...
  }
});

回答3:

buttonIcon.setBorder(new EmptyBorder(0,0,0,0));

回答4:

button.setBorderPainted( false );

回答5:

This can be done easily in netbeans by setting the contentAreaFilled Property to False

回答6:

    BufferedImage buttonIcon = ImageIO.read(new File("myImage.png"));
    button = new JButton(new ImageIcon(buttonIcon));
    button.setBorderPainted(false);
    button.setFocusPainted(false);
    button.setContentAreaFilled(false);

回答7:

just write this

button.setContentAreaFilled(false);

As far i know, there is no easy way of doing it, you will need to override the "paintComponent" method of the JButton class to aint your image, if you only want to display an image and behave like a button, you can add a JPanel wich draws the image (clicky) and add a MouseListener/MouseAdapter to handle the "mousePressed" event

I followed below steps and i could create an 'ImageButton' successfully.

Create a JButton
Added an action listener
Set an image icon (note i have placed the info.png icon in the src\main\resources folder and loaded using class loader). The project structure is as here.
Set an empty Border
Disabled the content area filling
Disabled the focusability
Added to the contentPane

PFB the code that worked for me

JButton btnNewButton = new JButton("");
btnNewButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("Info clicked");
    }
});

String iconfilePath = this.getClass().getClassLoader().getResource("info.png").getFile();
btnNewButton.setIcon(new ImageIcon(iconfilePath));
btnNewButton.setBounds(10, 438, 39, 31);
btnNewButton.setBorder(BorderFactory.createEmptyBorder());
btnNewButton.setContentAreaFilled(false);
btnNewButton.setFocusable(false);
contentPane.add(btnNewButton);

The output button resulted from above code is as below
