The Xul Chronicles: Origins
However, if you need to work with large or dynamic datasets, currently you have to code the data-to-widget management yourself - because it's not practical e.
Ability to mix-in any AWT Components with Thinlet widgets would be a fantastic feature - but I understand that it is technically quite difficult, perhaps impossible. Ability to nest arbitrary components would be very useful, too - e. This is probably not as complicated as it seems, but the event handling code would have to be reworked Some time ago I had a mostly working implementation of that feature, but I finally admitted a defeat after puzzling over the event handling methods While in a dreaming mode Andrzej Bialecki: Plugins.
With the latest release I added a plugin framework, which allows others to write external components for working with Lucene indexes. This could be e. This is a sort of "escape hatch" for me as well - now not only I can add functionality to Luke, others are welcome too, and they have some sort of framework to build upon and to ease the pain of directly diving into the main code By the way, I think that's one of the major challenges for every Open Source project - to provide a sufficiently open and understandable framework both in a programmatic sense, and in the way people collaborate in the project , so that others may join you in the development.
I've seen lone riders, who burnt out after a year or so, and their pet projects have been abandoned, I even experienced such burnout myself - so, providing a good framework, good documentation, and a helpful hand means for me less burden in the future and more chances for the project to succeed - and to surpass my vision.
Andrzej Bialecki: If time permits I am somewhat discouraged now from working on the core Thinlet, because of its complexity - I implemented two widgets sidebar, and "link" button , and I know I simply have too little time nowadays to sit whole nights tracking some obscure code paths But I would like to stay involved, at the least helping to manage the CVS and the release process, and hopefully working on some well-defined extensions. I'm convinced that the future of the project depends not only on how many users it gains, but also how many active developers and contributors it can attract - that's why I keep advocating for the openness in the development process, and for simplifying the core logic.
All of us know how it is to be a newbie, and I wouldn't want to see Thinlet fall into neglect because it's perceived as too complicated to understand or extend. We use Java and XML and that's pretty much it. We chose to use an XML syntax for styles for reasons of consistency.
Q: Do you have a favourite scripting language for the Java runtime? Any plans for adding support for scripting to XUI?

Luan O'Carroll: From the small exposure I have had to Jazzy I would say it is very impressive and has lots of nice features so that will probably be the choice. There are no immediate plans for adding scripting to XUI and we don't see any great need for one. Having said that, we realize many people like to use scripting so even if I'm not a fan we will probably provide the option of using scripting at some stage, it's just not at the top of the to-do list yet. Of course if somebody would like to help we'd welcome contributions.
Q: Do you have any plans of adding web-style form submission tags to XUI? What's your recommended approach for data-binding for XUI? Luan O'Carroll: Definitely, we are actively working on ways of making it even easier to do 'simple' business processing. We want to end up with a situation where the non-programmer can grab something like a schema and visually build and deploy working forms. I expect that the toolkit needed to enable such an approach will include standard web style actions like form submission.
XUI includes extensive data binding features and there are commercial extensions to the data binding for specific application areas e.

Forms, Surveys, Catalogues. Data bindings can be declared along with the UI or they can be configured dynamically. How the bindings are used is really quite application specific. Carousel, a commercial add-on from Xoetrope extends the data bindings to allow transfer of data from client to server in such a way that the application developer can pretty much ignore the location of the data. Once some routing information has been specified the toolkit will take care of everything else. Can you tell us if and how the mark-up differs when you either choose AWT or Swing?
Luan O'Carroll: There is a core set of components where the mark-up is identical. Switching toolkits is simply a matter of changing the start-up class, and normally no changes are needed to accommodate a switch to Swing. There are a few attributes that will be ignored when switching from Swing to AWT but generally they have little or no impact.
Luan O'Carroll: I think there are some nice features but overall its too complicated and doesn't go far enough in separating programming concerns. XUI doesn't have to deal with the legacy that XForms addresses so we have perhaps had more flexibility in terms of design. The objective is to make it possible to build applications with the minimum of coding. Today let's welcome Jazilla prodigy Mathew McBride. I live in Australia, and I'm currently doing year 8 in high school. I've learnt almost all my skills in the IT area by myself. When Netscape 6 came out I was interested in seeing how its interface was themed and how the whole thing worked.
Mathew McBride: Back in , I was involved in the flight simulation scene quite a bit. I decided to write a GPL'ed application and server backend in order to automate processing of data in Virtual Airlines. Some googling turned up Jazilla, which was a long defunct project at the time. I spent a few days looking at the codebase and took over the project soon after.
Mathew McBride: Back in , Netscape was rewriting the entire communicator suite in Java, in an effort called "Javagator" and "Xena" by some people.
The effort, sadly ended up dying in the corporate warfare that was Netscape at the time. The project continued on for the next two years, producing two Milestones, but dying off in See the Wired story for some history. I had a look at Jazilla in August and decided this would be a perfect project to work on. I soon took over leadership of the project and rescued it from the dead. Based on the elements on the DOM tree, a Java class set up to handle a particular element. These construct the equivalent Swing widgets which are displayed.

Do you have a separate distribution? What are the dependencies for jzXUL? A seperate distribution with all external libraries in the box, but without Mozilla chrome will come about sometime in the future. Do you use reflection? Do you use hand-coded glue code? In the future construction of element classes will be done in a simular way to the HTML engine, by reflection. Thanks Mathew McBride. I've posted many of them or hints about them over the last year or so. Remote XUL, improved templates, a canvas tag, and so forth. In some cases, I started an implementation only to be blocked by some non-implementation related issue.
