Re: [svg-developers] getClientX() and getBBox() not in Firefox 1.5?
getBBox() is also supported, although there does seem to be something buggy about it. I haven't troubled to track it down, but I think it only works on visible, rendered objects. Yep, there is a problem in that you have to wait until *after* onload... but not in onload. So you have to settimeout in onload and hope that everything is rendered. So there is not a safe time to really check this per se... it may be right, it may not be for that brief startup moment. I believe that there is a bug filed on this already.

Re: [svg-developers] getClientX() and getBBox() not in Firefox 1.5?
Hi Jeff,
On FF 1.5, you can't also do, for example :
var myObj=document.createElementNS(NameSpace, 'rect')
myObj.setAttribute('x',20)
myObj.setAttribute('y',20)
myObj.setAttribute('width',20)
myObj.setAttribute('height',20)
document.getElementById('WhereIputRects').appendChild(myObj)
var bb=myObj.getBBox()
Is it the same bug?
Cheers
Jérôme

This is a very unfortunate problem. :-(

Rendering is asynchronous so at the point in time the following line is
called the 'rect' probably won't have been rendered. You could try calling
document.documentElement.forceRedraw() here, but I don't think forceRedraw
works properly either. :-(
var bb=myObj.getBBox()

Hi Jeff, svg-developers@yahoogroups.com wrote on 10/17/2005 02:06:04 PM: Hmmm, forceRedraw *should* work in an ideal world-- but I haven't tested it. Essentially this is a problem with many implementations-- the DOM is lazy with respect to rendering hints. In SharpVectorGraphics I think that the bbox is a cached item-- if it is not found in the cache then we generate it on request (of course this implies a forced render). No it doesn't it implies that the geometry is calculated, nothing needs to be rendered. That is typically the act of putting bits on a device, and is generally much more expensive than just calculating the bbox of content. In general, I think that most implementations (other than Batik) do not rerender within a function block-- but do a complete rerender of changed portions at the end of the block when control is passed from the script. Batik maintains geometry as the DOM is manipulated, we do not 'rerender' on every change. Which is to say that this type of problem isn't unexpected-- but you have to be able to obtain those rendering properties on the fly. Even if you can do that though, the resulting page will likely be sub-optimal. In what sense 'sub-optimal'? You almost certainly need to calculate the BBox in order to render the content, so why does doing it before the rendering make it worse than during the render? Yahoo! Groups Sponsor ~-- Get Bzzzy!

getClientX() is not a standard method of the DOM, you should just use
evt.clientX instead. I'm pretty sure that'll work in Firefox.

Re: [svg-developers] getClientX() and getBBox() not in Firefox 1.5?
Thanks Antoine, but no luck.
I tried this:
function putit(evt){
alert(happy)
alert(evt.clientX())
}
The first alert() fires just fine -- the second is ignored (as is everything
after it).
Having not had experience with beta software for about 20 years, I went
ahead and reported it to the Mozilla folks -- hopefully I was not too hasty.

RE: [svg-developers] getClientX() and getBBox() not in Firefox 1.5?
Hi, David-
It's not:
evt.clientX();
it's:
evt.clientX;
getBBox() is also supported, although there does seem to be something
buggy about it. I haven't troubled to track it down, but I think it only
works on visible, rendered objects. This behavior may or may not be correct,
but certainly is inconvenient when you are trying to predetermine, say, the
size of a text block in order to wrap a rectangle around it... which means
it will end up getting rendered twice, possibly with a flicker... so,
another performance hit.
Regards-
Doug
