Introduction

Setting up an application file structure

First set up the application file structure to the following:

 /xulapp
    /chrome
       /content
          main.xul
       chrome.manifest
    /defaults
       /preferences
          prefs.js
    application.ini

For more information about this section please visit the following link: File/Folder Structure

Setting up the application.ini file

The following is a sample application.ini file.

 [App]
 Vendor=Mylau
 Name=Hello World Application
 Version=1.0
 BuildID=20060101
 Copyright=Copyright (c) 2006 
 ID=xulTestApp@mylau.org
 
 [Gecko]
 MinVersion=1.8
 MaxVersion=1.8


To find more information about this file, click on the following link: application.ini File

Setting up the chrome.manifest file

For this example, the chrome.manifest file contains the following information:

 content myapp file:content/

To find more information about this file, click on the following link: chrome.manifest File

Setting up the prefs.js file

The following was used for this simple application.

pref("toolkit.defaultChromeURI", "chrome://myapp/content/main.xul");


The pref function needs to be passed in two arguements. In this scenario, this document provided an explaination on what those two arguements are:

  • toolkit.defaultChromeURI is a preferences which allows a simple XULRunner-based application to open a new window
  • chrome://myapp/content/main.xul is the location of the main XUL file.


To find more information about this file, click on the following link: prefs.js File

Creating some XUL

For the simplicity of this application, we're going to create a simple XUL window that says hello world.


Open the file, "main.xul". This file is located in the following location:

 /myapp
   /content
     main.xul

Write the following code into the xul file. This code will popup a XUL window with the words "hello word"

  <?xml version="1.0"?>
  <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

  <window id="main" title="My App" width="300" height="300"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
    <caption label="Hello World"/>
  </window>
