Hi, Burkhard-
I don't understand your questions. Perhaps you misunderstood the intent of
my sample. It's a very basic example of how to do drag-and-drop with groups.
I made a point of commenting the code, so that anyone who wants to figure
out how to adapt it to their own purposes can very easily do so. Obviously,
you will have to tear it apart and fit it into your own codebase.
To speak on your specific concerns:
1) Yes, it will drag any group (although this example might not work as-is
for grouped 'use' elements)... Keep in mind that it assumes that the element
grabbed is a top-level child of the group to be moved; if your SVG hierachy
markup is more complex than that, there are ways to find the "proper" group,
including testing against id and such;
2) Well, SVGDocument is just what I call it... Nothing magic about that,
just change the variable name. You could do something like this, too:
function Grab(evt)
{
//get the document element, if it doesn't exist
if ( !SVGDocument )
{
Init(evt);
}
// find out which element we moused down on
var targetElement = evt.target;
...
};
Again, nothing magic about the onload event... You just need to initialize
the variables once.
