XUL files

A XUL script is an XML file specifying a GUI and containing:

• The declaration of the UI using XUL controls
• The declaration of the XUL scripts used to interact with the controls. As for HTML files, these scripts can refer to external script files, or be embedded in the XUL file

Example

Suppose the following XUL script:

      <?xml version="1.0"?>
      <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
      <window id="Hello" title="Hello" orient="horizontal" width="250" height="100" screenX="500" screenY="500"      
      xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
         <script>
      function clicked(){
      alert('Hello World!');
      }
         </script>    
         <button label="Push Me!" oncommand="clicked()" />
      </window>
