Re: How to get the element form SVG file.

[comlong zhao <co...@gmail.com>]

Hello:
   Thanks a lot for your help. But so pity, i have not achieved it. I just
use your demo code now, and when i run my java3D code, your code is running
and i could get a lot of bufferedimage. Now, when i click one key or mouse
button, i could call one method which is in your file. So i think i create
one method like that:
  AWTEventDispatcher ad = new AWTEventDispatcher();

  public void interactive(){
     ctx.addDOMListeners();
    ad.setRootNode(gvtRoot);
   ad.mouseClicked((MouseEvent) *evt*);
    manager.getUpdateRunnableQueue();
}
 is that right?
 and I do not know how to use the evt, for the java 3d, i just could call
the method, but i do now know how to transform the parameter now. For the
basic way, I just want that when i press one button or click the mouse, i
could call the method and then i could get the new Bufferedimage.

  Sorry to trouble you again.
  Thank you very much.
  zhao long
