free hand

yes, if you track all the coordinates
(evt.clientX/evt.clientY), then 
translate them into the local coordinate system (using
.getScreenCTM()) 
and then creating and updating the "d" attribute
of a path element.

there are two methods: either you use the methods of the DOM

SVGPathElement - see http://phr
ogz.net/ObjJob/object.asp?id=101 or you 
create a new textstring everytime a coordinate is added. It
might be 
enough just to concatenate the new coordinates to the
existing "d" 
attribute.

i try to add a path creating a textstring but there is a
problem...i don't
know what values to use (M C Q T etc..)...for example: if i
use C value,
what value can i add in C parameters? because C is C x1,y1
x2,y2 x,y but i
have only the x,y values...
pathValue = "M "+
startPt.getX()+","+startPt.getY()+" C ";
pathValue = pathValue + pt.getX()+ ","+ pt.getY()+
" " + .......(what??!!);
path.setAttributeNS(null, "d", pathValue);
