I tried to do the following with no success (no visible change to
JSVGcanvas):
rq.invokeLater(new Runnable()
{
public void run()
{
elem1.setAttribute("style","fill:red;display:inline;opacity:2;");
}
});
I also tried invokeAndWait but I got an error:
java.lang.IllegalStateException: cannot be called from RunnableQueue thread
Another related (may be unrelated) question--do we need to mess with GVT to
change DOM?
