这里面包含了一百多个JAVA源文件

// Create a nummber spinner
    JSpinner spinner = new JSpinner();
    
    // Disable keyboard edits in the spinner
    JFormattedTextField tf =
        ((JSpinner.DefaultEditor)spinner.getEditor()).getTextField();
    tf.setEditable(false);
    
    // The previous call sets the background to a disabled
    // color (usually gray). To change this disabled color,
    // reset the background color.
    tf.setBackground(Color.white);
    
    // The value of the spinner can still be programmatically changed
    spinner.setValue(new Integer(100));
