JButton ImageIcon不起作用

Question

So im trying to get a specified image as the "look" of the Jbutton but it just isnt working. any ideas?

The code:

JButton btnClose = new JButton("Close");
    try {
        Image img = ImageIO.read(Window.class.getResource("resources/quit_button.bmp"));
        btnClose.setIcon(new ImageIcon(img));
      } catch (IOException ex) {
      }

btnClose.setVisible(true);
btnClose.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent e) {
        frame.dispose();
    }
});

My image path is: C:\\Users\\ *User*\\workspace\\Pede\\pede_Exe\\resources\\quit_button.bmp

Answer 1

"Isn't working" isn't a lot to go on, but my suspicion is that ImageIO is throwing an exception before setting the icon. This is often (but not exclusively) because your path is wrong.

First and foremost, print your stack trace. That should be, for you,

ex.printStackTrace();

in your catch block. That stack trace is an arrow to the problematic code, and often has a plain-English explanation attached to it. Get in the habit, you won't regret it.

Second, see to it that you're looking in the right place for your image. The easiest way to do this can be found here: Find where java class is loaded from

As you can see, there are a lot of possibilities. If the path of your class, compounded with the path of your resource, is not a real thing, then ImageIO will not find your icon.
