Subject RE: removing elements
Date Thu, 13 Apr 2006 19:55:43 GMT
Yasmin,
It will work, but the question is how you would like to do. In my
application, I remove all the elements from the circleGroup and add the new
set of circles. You could use the method below to remove all the child
elements

void removeAllChild(Element elt)
{
	while (elt.getFirstChild() != null)
	{
		elt.removeChild(elt.getFirstchild());
	}
}

Say, if you call your circle group to be circleSet, the you would call the
above method passing the circleSet as an argument.

Hope, it helps,

Javid

Avid,

...would it be better if I removed all the 'circle Group' and then add it
again with only the circles I want to display...?
