Read up on event life cycle, specifically about capture, target and bubble phases. dispatchEvent(new Event(eventType)); will dispatch the event. But since it's a renderer (let's say a datagrid renderer for example sake), the only way for you to listen for the event is on the datagrid itself, i.e. datagrid.addEventListener(eventType, handlerFunction);
Adding the event listener like this is listening for events from the given type, *dispatched from the datagrid*, but it's your renderer that is dispatching the event, not the datagrid... The way to make this work, is dispatch it from the renderer with bubbling - which will make it bubble up the display list heirarchy renderer->datagrid ->etc... and will make your handler catch the event. So, a long story short, dispatch the event from the renderer like this: dispatchEvent(new Event(eventType, true)); But you should really read up on event phases 2009/7/5 j2me_soul <[email protected]> > > > How can let the parent of itemrenderer know something is happened ? > I use dispatchevent function, but it doesn't work. > > > > ------------------------------ > 200万种商品,最低价格,疯狂诱惑你<http://count.mail.163.com/redirect/footer.htm?f=http://gouwu.youdao.com> > >
