Interactors

[Jamie]

Forgive me for yet again asking this question: Interactors - what and how?   Specifically, I am constructing a UI with JSVGCanvas as my main component. I have a button on the toolbar which I want to use as a 'Zoom In'. When the user fires the event ...   private void zoomInButtonActionPerformed(ActionEvent evt) {     // telll Interactor to Zoom In ?? }   Am I wrong in assuming that interactors can be called like this. Or do I 'manually' set the viewbox/currentTransform. I vaguely understand that Interactors are there and work just from the fact I can use the mouse and CTRL keys to perform actions.   I noted that the Batik guys were giving a presentation at SVG Open 2003 where they explained the use of Interactors. I can view the abstarct but the presentation does not seem to be available. Is it available? This would be most useful to me ;-). The documentation (website/API) is relatively sketchy for an 'absolute beginner'.
