Am trying to set a background image for my frame but it does not work. I tried this link:
Setting background images in JFrame
The code:
setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("/Images/about.png")))));
I tried adding the above code to my Contentpane but it does not work.
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MainMenu frame = new MainMenu();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public MainMenu() {
setIconImage(Toolkit.getDefaultToolkit().getImage(MainMenu.class.getResource("/Images/bug-red.png")));
setTitle("Automated Bug Fixing");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 712, 458);
contentPane = new JPanel();
//contentPane.setBackground(new Color(220, 220, 220));
contentPane.setForeground(new Color(32, 178, 170));
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
*setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("/Images/about.png")))));*
The basic concept looks fine.
The only possible reason you might be getting problems is if the image doesn't exist.
It looks look you are trying to reference an image that should exist within the context of the Jar
Instead of
ImageIO.read(new File("/Images/about.png"))
Try
ImageIO.read(getClass().getResource("/Images/about.png"))
Instead.
Also, don't swallow exceptions, make sure all exceptions are been logged at the very least
