Adobe's SVG Viewer allows me to use a JavaScript object as an event handler.
The object needs a handleEvent method to follow the EventListener interface.
For example, the following code creates a Button object that handles various
mouse events for a specific svg node.
button = new Button();
someSVGNode.addEventListener(mousedown, button, false);
someSVGNode.addEventListener(mousemove, button, false);
someSVGNode.addEventListener(mouseup, button, false);
function Button() {
...
}
Button.prototype.handleEvent = function(e) {
var type = e.type;
if ( this[type] != null ) this[type](e);
};
Button.prototype.mousedown = function(e) { ... }
Button.prototype.mousemove = function(e) { ... }
Button.prototype.mouseup = function(e) { ... }
When I try this in Batik, I get the following error: Cannot convert [object
Object] to org.w3c.dom.events.EventListener. So, I'm wondering if it is or
will be possible to use JavaScript objects as event listeners.
Thanks,
Kevin
