Re: [svg-developers] accessing children nodes inherited from defs
Hi Aashish
Once you've describe an object in defs section, here Gr, it is
considered as one single element.
So, when you use it by use element, you can't access to any child of
this object.
On the other hand, in your example, if you change some attribute of the
rect of Gr, it will impact any reference to gr, ie u1 AND u2,
because you've changed the symbol itself.
You cannot apply modifications only to U1, and not to U2.
But:
if you have something like
defs
rect id=myrect x=10 y=10 width=50 height=60/
/defs
use xlink:href=#myrect id=U1
use xlink:href=#myrect id=U2
, you can define differents color for the two use. To do that , change
the use attributes directly :
doculent.getElementById('U1').setAttribute('fill','blue'), and not the
definition of the referenced object.
That way, you can have different representation of a single referenced
element. But you cannot change its définition.
Hope it helps

SVG gurus,
If I have a SVG like:

defs
g id=Gr
rect
text
/g
/defs
use id=U1 xlink:href=#Gr ... /
use id=U2 xlink:href=#Gr ... /
...
For the object defined by ElementId = U1, is there a way to access
the inherited children from Gr. Meaning, is access to U1's
rectangle child or U1's text child allowed.
svgdoc.getElementById(U1).childNodes doesn't give any elements.
Is there another way to access those children?
If not, and I have to access the children elements for each rendered
element, (non-def), would defining a g element with actual 'rect'
and 'text' elements be the only way to achieve it?
So, for above, I will be doing
..
/defs
g id=U1rect .../text ...BLAH/text/g
g id=U2rect .../text ...BLAH/text/g
...
TIA,
Aashish

Re: [svg-developers] Drag and Drop for groups
hello Burkhard. I don't have too much time now, i'm sorry The main issue for this problem is handling the mouse. You must detect onmousedown event, memorize it and the object on which you've clicked, then react to onmousemove by moving the object, until onmouseup is detected. The onmousemove and onmouseup can be fired on the SVG document itself, but onmousedown must be fired on the group only.

[svg-developers] Re: servlet and getURL()
Hi,
if you want to load and display data every millisec, than SVG is probably not
the right tool.
I don't know how fast it can update and load data, but I guess it is only once
or a handful
times per second. But that depends on your clients processor and network speed.
One millisec update time is anyway much, much more than a human can perceive.
As far
as I know a smooth movement starts with a framerate of 25 frames per second,
wich is an
update every 40 milliseconds.
But I don't believe that current SVG viewer can do getURL() and update every 40
milliseconds.
As to getURL examples: just google for getURL and SVG and you will find plenty
examples.

Re: [svg-developers] SVG Element
It is a DOCTYPE declaration. Paraphrasing from SVG Unleashed, a document type definition defines the permitted structure of an SVG document, and, you may not need the DOCTYPE declaration if, for example, your browser recognizes an svg file by the file extension. It also states that it is wiser to include the DOCTYPE declaration. I know that you don't need it for svg files that are displayed in ASVG3 in IE. If you are using a validating editor (e.g., XMLSpy) you will definitely want to use the DOCTYPE. I'd keep the DOCTYPE. - Do you Yahoo!? Yahoo!

This was discussed here not too long ago, so it should be easy to find the thread. The consensus was that you couldn't expect to be getting data via getURL() more than a few times a second. It doesn't mean it can't be done, just not the way that you suggested. If you want to use getURL(), you could accumulate the sensor data on the server and send it down in chunks. - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

sketchy idea of what I have in mind.
How I can I implement a simple getURL()? Will it be something like
svg ...
script ...![CDATA[
function acquire() {
getURL('/servlet/sensorservlet',fn)
}
function fn(obj) {
setTimeout('acquire()',1)
}
]]/script
/svg
Thanks for your help.
---
private int data;//data holds sensor value
public class Sensor extends HttpServlet
{
public void init(ServletConfig config) throws ServletException
{
super.init(config);
MyMonitor Monitor = new MyMonitor(); //data acquisition class
instantiated
data= Monitor.start(); //method polls sensor for data
} //end of init
protected void doGet(HttpServletRequest req, HttpServletResponse
res)
{
res.setContentType(text/html);
res.setHeader(pragma, no-cache);
ServletOutputStream out = res.getOutputStream();
out.print(HTMLHEADTITLESensor
Data/TITLE/head);
out.print(Sensor DataBR);
out.print(data);
-
-
-
out.print(/HTML);
out.close()
} //end of doGet
} // end of Sensor Class

Re: [svg-developers] svg viewer for .NET
Which is the favorite svg viewer for builing now such a comercial .Net windows application? We are using SharpVectorGraphics. I have currently been enhancing the interactivity portions of the library with the help of a couple of others. The development is being supported by a company in Colorado, US and it looks like a couple more steps will be made this round. With that said there is still quite a lot unimplemented-- and unoptimized. If you decide to try it, use the CVS version.

Re: [svg-developers] accessing children nodes inherited from defs
For the object defined by ElementId = U1, is there a way to access the inherited children from Gr. Meaning, is access to U1's rectangle child or U1's text child allowed. svgdoc.getElementById(U1).childNodes doesn't give any elements. Right, you have to get the use element's InstanceRoot or AnimatedInstanceRoot. This returns an SVGElementInstance. From that you can get the CorrespondingElement (which in 99% of cases will be a g that is wrapping the reffered-to construction). Now, depending on the interpretation you can just go from there with ChildNodes and all the rest-- but some may interpret the spec to mean that you must always navigate via the SVGElementInstance and get the ChildNodes of that which returns an SVGElementInstanceList-- so in that case you would have to get the CorrespondingElement each time. I am not sure who supports this though... my guess is ASV6 does and ASV3 does not. SharpVectorGraphics supports it in CVS.

Re: [svg-developers] Re: Performance problem
I'm curious if you can just avoid calling removeChild. Here are some alternatives: - set the display attribute to none this will make it not visible - call appendChild on another element this will remove from current location and put in the new location. You could make a document fragment, call append child on the fragment, then let the js gc collect it: var group = parseXML( 'g xmlns=http://www.w3.org/2000/svg; display=none /', svgDocument ).firstChild; group.appendChild( childToDelete ); group = null; after that, the javascript garbage collector should collect it when it feels like it. If this solves your problem let me know, I'm curious!

XAML is only available in preliminary versions of the markup format, and then you'd need some type of clientside renderer, which are also in pre-beta. The eventual download size for WinXP may end up being, I dunno, a hundred times larger than the Adobe SVG Viewer, so likely adoption rates seem currently difficult to predict. You can generate SVG-style XML with many types of server software. Once you've got a valid SVG file, then it should be viewable in whatever compliant viewer your audience has installed. We have to build a ms windows application, which should view a svg graphic and dynamically change some svg elements as well as process events at runtime. Have you examined whether any of the available SVG clients which your audience might install are capable of performing the tasks you desire...? jd John Dowdell, Macromedia Developer Support, San Francisco (Best to reply on-list, to avoid my mighty spam filters!)

Hi, ?? .NET usually runs on the server (depending on whether you include the CLR in your definition), and SVG is usually rendered in the web browser, true...? (...) You can generate SVG-style XML with many types of server software. Once you've got a valid SVG file, then it should be viewable in whatever compliant viewer your audience has installed. well, when building a standalone application the concept of server doesn't realy apply :) What SharpVectorGraphics does is to render a SVG image, the same job adobe's svg plugin does (for example) when a browser is used to view a SVG. No browser is involved in this case, i think. /FC - 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] SVG#, examples and interactivity
Where might I find examples and/or documentation on SharpVectorGraphics? I will be using it to show an SVG in my C# app but I will also need some interaction. For example, when clicking a certain element it should become highlighted by changing its color. I've read about this being possible (not sure where though) but couldn't yet figure out how. I'm not sure this is the best place to ask something about SVG#, please also advise if there's a better place to discuss it.

[svg-developers] Re: Change Mouse Pointer in SVG
See: http://www.w3.org/TR/SVG/interact.html#CursorProperty cursor attribute is not supported on ASV 3.x but is supportd in ASV6. Sorry, don't know about other browsers. Someone on this mailing had suggested a basic hack which would work in current implementations. Add a wrapper a /a tag around the element(s) that you want to change the cursor on. It would become a hand. There might be other ways to achieve this. (e.g. a hand-like path element that becomes active with mouseover and then moves with the mouse using mousemove ) Don't have an example.

Re: [svg-developers] SVG#, examples and interactivity
Where might I find examples and/or documentation on
SharpVectorGraphics? I will be using it to show an SVG in my C# app
but I will also need some interaction. For example, when clicking a
certain element it should become highlighted by changing its color.
I've read about this being possible (not sure where though) but
couldn't yet figure out how.
// After loading...
ISvgDocument doc = svgPictureBox.Window.Document;
doc.RootElement.AddEventListener(click, new
EventListener(ClickHandler), false);
doc.RootElement.AddEventListener(mousedown, new
EventListener(MouseDownHandler), false);
doc.RootElement.AddEventListener(mouseup, new
EventListener(MouseUpHandler), false);
doc.RootElement.AddEventListener(mousemove, new
EventListener(MouseMoveHandler), false);
doc.RootElement.AddEventListener(mouseover, new
EventListener(MouseOverHandler), false);
doc.RootElement.AddEventListener(mouseout, new
EventListener(MouseOutHandler), false);
etc
public void MouseOverHandler(IEvent e)
{
SvgElement aGraphic = null;
if (e.Target is SvgElement)
aGraphic = ((SvgElement)e.Target);
else if (e.Target is SvgElementInstance)
aGraphic =
(SvgElement)((SvgElementInstance)e.Target).CorrespondingUseElement;
aGraphic.SetAttribute(stroke, cyan);
svgPictureBox1.Render();
}
And so on... keep in mind, this only works from the CVS version,
re-rendering is not optimized, and if you are planning on using GetCTM,
GetTransformToElement, GetScreenCTM or the like, wait. I will be
finished in a couple more days I think...

[svg-developers] Mozilla getStyle GetStyleData JavaScript etc
The Code below apparently is an Adobe specific way of setting fill
color. I believe GetStyleData would be the Mozilla equivalent. Not
sure though since I can't get it to work. Does anyone know how to do
this in Mozilla? I've had some limited success altering CSS
attributes, but would like to avoind it if possible. Thank you.
svgobj = document.getElementById(id);
svgstyle = svgobj.getStyle();
svgstyle.setProperty('fill', 'yellow');
