The simplicity and ease of expression of XUL makes it a great technology for GUI prototyping.

XUL has a sister language, XBL, which allows you to perform much of this binding using declarations, reducing the amount of required script.

XUL takes the very-thin-client model of HTML and thickens it up a bit.

The toolbar code is interesting -- Mozilla XUL allows for modern toolbar styles that include both direct activation and child pull-downs.

XUL, JavaScript, and CSS code are all interpreted languages, and each lacks the formality of fully object-oriented languages.

You can use data in other formats and create RDF data from it, which will be bound to XUL elements.

The client side of this solution is a Firefox XUL extension, which adds AtomClip context menu options for copying to and from the Atom feed.

The web content is loaded in an offscreen XUL browser element and is then painted into an HTML Canvas element that is visible to the user.

What is a little more common is some kind of IO operation, like accessing a Web service, or reading from the local file system.

XUL is the main technology behind Firefox and its extensions.

The menus, toolbars, scrollbars, and dialog boxes of many Mozilla-based browsers are built using XUL documents.

The Workers API just removed any excuse to not use multithreading to improve your XUL applications .

The first step is to build an extension with the XUL and support files as developed in the previous article.

Some of the attributes used in XUL tags are shared with HTML, such as id, class, value, accesskey, readonly, and selectedIndex.

Listing 1 is the . zip file directory for an extension I prepared using the XUL, JavaScript, and CSS from the previous article.

You've seen how naturally XUL mixes with the basic building blocks of Web development.

Familiarity with XUL development is certainly beneficial, but not strictly required.

The features of XUL illustrated in this article are just the tip of the iceberg.

Attribute values in XUL must be placed inside quotes, even if they are numbers.

Listing 2 (overlay. xul) is an overlay to add a menu item for launching the stats viewer window.

Since XUL is a flavor of XML, the many W3C standard DOM interfaces are available.

For example, you ll be able to use similar techniques to write stylesheets that produce XUL or XAML to bind directly into the browser.

Start with the XUL code for the user interface (see Listing 1).
