Hi Simon, SVGSVGElement.getIntersectionList( rect, referenceElement ) or .getEnclosureList(rect, referenceElement) would theoretically do the job.
Unfortuanetly it is only implemented in Batik ;-( It takes a rectangle as input, but you can specify a very small rectangle. You can also ping the viewer developers to implement this very useful method. Here is a very simple example: <?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg"; xmlns:xlink="http:// www.w3.org/1999/xlink" width="100%" height="100%" viewBox="0 0 1024 768" onload="testGetIntersectionList()"> <script type="text/ecmascript"> <![CDATA[ function testGetIntersectionList() { var svgroot = document.documentElement; var myRect = svgroot.createSVGRect(); myRect.x = 460; myRect.y = 460; myRect.width = 1; myRect.height = 1; var intersectList = svgroot.getIntersectionList(myRect,null); for (var i=0;i<intersectList.length;i++) { alert("id of intersected element="+intersectList.item(i).getAttributeNS(null,"id")); } } ]]> </script> <title>Demonstration of the method SVGSVGElement.getIntersectionList()</title> <rect id="redRectangle" x="400" y="400" width="200" height="200" fill="red" /> <rect id="blueRectangle" x="450" y="450" width="200" height="200" fill="blue" /> <rect id="yellowRectangle" x="50" y="50" width="100" height="100" fill="yellow" /> <rect pointer-events="none" x="458" y="458" width="4" height="4" fill="green" /> </svg> --- In [email protected], "simonshutter" <[EMAIL PROTECTED]> wrote: > > Hi folks, > > Is there a way that I can use the event model to identify all elements > that overlap a specific point on a mouse down/move event?
