Identifying each circle
Hi Thomas,
With the zooming problem if I set 'r' from '0.001' to '1' then the
'circle-rings' appear on the canvas!
Anyway, I would like to be able to identify each 'circle' when I click it,
i.e, attach a number (1,2,3...), so the user can have a visual reference
for each circle. How can I attach a number, I tried:
String num = Integer.parseInt(num) // Keeps record of num of Clickd Circles
elt.setAttributeNS(null,"text",num);
Thx

Hi Javid,
Yes, after studying ur code I understand what its meant to do - but for
some strange reason I'm getting the followin error:
org.w3c.dom.DOMException: The current document is unable to create an
element of the requested type (namespace: http://www.w3.org/2000/svg,
name: textID).
...any thoughts?
thx

Hi Yasmin,
Sorry I wasn't very clear, I was using that piece of code for my 'g'
elements, so I suggest you create a text element when a user clicks on your
circle and translate it to the circle's position. If you look at Thomas's
code (look couple of emails before) that uses SVGLocatable to get the
position of circle and use that position to set the co-ordinate positions of
your new text element.
Thanks,
Javid

Hi Javid,
How did you declare the variable 'rg' and also the 'CircleElement' does
not have 'appendChild() method???

Hi Yasmin,
I guess when you need to add text, you have to create a text element and
append it to the circle element. That's how I display the text. Something
like this.
Element textID = svgDocument.createElementNS(SVG_NS, "text");
Element textSpan = svgDocument.createElementNS(SVG_NS, "tspan");
textSpan.setAttributeNS(null, "x", "15");
textSpan.setAttributeNS(null, "y", "25");
textSpan.setAttributeNS(null, "fill", "#17238C");
textSpan.setAttributeNS(null, "font-family", "'Arial-BoldMT'");
textSpan.setAttributeNS(null, "text-anchor", "middle");
textSpan.setAttributeNS(null, "font-size", "18");
rg.w3c.dom.Text tempText = (org.w3c.dom.Text)
svgDocument.createTextNode("Your text goes here");
textSpan.appendChild(tempText);
textID.appendChild(textSpan);
circleElement.appendChild(textID);
Hope it helps.
Javid
