Re: [svg-developers] Re: XForms in standalone SVG
That is very helpful thanks Jim, I had not realised that I could do that with ASV and IE...pretty cool. Unfortunately I only saw your email this morning and I have already taken what I learnt from the Text boxes done by Jan Klaas Kollhof and Holger Will and fixed the problems I was having with the Strayley form library. I will certainly be using your example in my next upgarde if the XForms/XBL/SVG option is still not mature. I am in the process of figuring out a way of showing the svg-developers what I have done to piece together my web app, but it may take a few weeks before I have completed all my testing, delivered it to the client and finalised things.

Hi Steve I had seen your simple XSLT based input box but not your others, the ASV6 one is great, I can not wait for ASV6 to be in production release (whenever that happens!?!!??!) i guess we have to wait for 1.2 full to become a recomendation... i would be happy if mozilla gets better text support, so i could get the textbox to run there. so I can implement it in my app, until then I will look into using your ASV3 version I think, I had a look on your site but found no links to those textboxes...is that on purpose? just click on the history 01 link on the main page: http://www.treebuilder.de/default.asp?file=history01.xmltype=html ok i know my site really needs a rebuild, i ve some prototypes for my new pages, but its all not done yet, though everything is better then the current version. I had seen Jan's before, but had not tried to integrate it, perhaps I will make a more concerted effort as it seems to have the functionality I need with respect to hightlighting text and keyboard interaction (similar to your ASV6 text box), the reason I did not persue it last time I saw it is because I could not get my head around the complexities of how he handles his classes, modules prototypes, handles exceptions etc... it all seemed very complicated, but as I said, perhaps I just need to nut it out. well if you are not afraid of some scripting, you could as well just write your own textbox. the key to text selection is: http://www.w3.org/TR/SVG/text.html#InterfaceSVGTextContentElement cheers Holger - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] Re: XForms in standalone SVG
Isn't it just as effective to build JS objects to manage the SVG-DOM nodes (their properties, any animation and any other needed functionally)? This gives us the freedom of not being locked into XHTML and still allows us to provide a dynamic UI - to truely become a one-page web application within the browser. I assume that a JS manager object could also interface with XFORMS; haven't attempted this yet. Using JS allows us to use any browser that supports XML, SVG, XFORMS, XBL, etc If I'm missing something important in my approach, please let me know as I'm already well into the project I'm working on concerning RAD for SVG. Dave --- In svg-developers@yahoogroups.com, Mark Birbeck [EMAIL PROTECTED] wrote: Hi Steve, Although I've said this before, I believe that architecting *first and foremost* in SVG is not sustainable. I know that people will reply by saying that they have successfully created applications that have hundreds of thousands of lines of SVG, but it seems to me that the 'mountain bike demo' discussion a week or so ago made it plain that--despite the incredibly impressive results--for most developers and projects this approach is not an option. I'll describe the architecture I am working towards, and then follow with an example that adds dynamic SVG buttons to an existing application by 'skinning' it, rather than changing the application. The SVG buttons will: * use filters to give a rounded effect; * obtain their captions from the XForms engine, and be updated if the data changes; * use the applications's CSS to obtain colours which will be used for the captions and the background; * use SMIL to 'fly' the button's label in, but use *CSS* properties to determine *when* to fly the text. This last point is I believe a very important development, in that we are not binding to specific events like mouse-over, but to CSS clasees. In other words, the functionality in the SVG button is *truly* independent, encapsulated and re-usable. ARCHITECTURE The archtitecture I would recommend to you is one in which the foundation of an application is an XHTML document. For now that's XHTML 1.1, but soon it will be XHTML 2. This foundation provides us with a simple framework into which we can put metadata about the document, links to stylesheets, and so on. Once we have a basic document, what goes inside it depends on what you are trying to do, but in general I would say that we want it to be as abstract as possible. We want to specify *what* we want to do, not how it will be done. If we want to collect an integer from a user, we just use the XForms input control, and bind it to a node of type xsd:integer. If we want to show an error message we should use the XForms message element. And so on. What we *don't* want to do--at this level at least--is start defining our application in terms of scripts that are non-portable, and don't capture the *intent* of our application. Although we have enabled our Sidewinder Viewer to cope with XForms, SVG, XHTML and MathML, I would suggest that of these, SVG is not an 'abstract' language but a rendering one. MathML is abstract, as is XForms, whilst XHTML has a foot in both camps! SKINNING So where does SVG come in? Well, once we have created our application at an abstract level--step 1 enter a number, step 2 request a customer, step 3 allocate the invoice, and so on--we are then ready to 'skin' it, and present it to our users. Ideal for this is XBL, and inside XBL modules is where we should put our SVG, VoiceXML, X3D or whatever rendering language we care to use. We can keep it hidden, and keep it manageable. We can share objects, replace them with others, or even let the user choose to 'skin' our application in a different way to the one that we intended. AN EXAMPLE If you have looked at our Sidewinder Viewer (available at http://www.formsplayer.com/download/swviewer-install.html) you might have seen that the latest version comes with a full-featured application that interacts with Google Desktop Search (GDS). The application is built using standard XForms techniques, with a few clever bits to make configuration easy. The UI is pretty 'traditional' but on the XForms Wiki we have an example that shows how to add an SVG widget to replace the normal buttons. See: http://www.xforms-wiki.com/bin/view/Main/XformsAndSkinning This topic has all the files needed to add animated buttons to the Google Search application, and takes you step-by-step through what is needed. There is also a small Flash video if you just want to see the results. CONCLUSION Note that the only changes needed to the actual application are a link in the header to indicate what binding rules should be used; the actual code to achieve the 'animated label widget' is kept in the XBL module.
