All of the dynamic stuff is fully available in Java as well as in JavaScript (EcmaScript). If you don't have any obvious dynamic elements in your document then you need to inform Batik to treat your document as dynamic, using JSVGComponent.setDocumentState(ALWAYS_DYNAMIC). You will have to add your listeners using the DOM interfaces (addEventListener) instead of using the event attributes (on click etc). > From: Andres Toussaint [mailto:[EMAIL PROTECTED] > Sent: Monday, October 24, 2005 1:19 PM > To: [email protected] > Subject: Re: Efficient way of "selecting" an element? > > SVG has the ability to dispatch events based on mouse actions, and the event > holds the object that triggered the event (which is not necessarily the object > holding the listener, in case it is a group), for example: > > <g onMouseClick="doEvent(evt)" > > <rect id="object 1" ...../> > <rect id="object 2" ...../> > <rect id="object 3" ...../> > <rect id="object 4" ...../> > </g> > > the event will be activated and dispatched only when the click is inside any > of the rect objects, and the evt.target will tell you what is the clicked object. > > You may also see the dragTutorial in the batik wiki to see how to add > listeners in the code: > http://wiki.apache.org/xmlgraphics-batik/DragTutorial > > regards, > Andres. > > p.s. the same is true for all other mouse events. > > On Oct 24, 2005, at 1:04 PM, Bishop, Michael W.
