@Events({"beginRender","afterRender"}) @MixinAfter public class RenderNotification extends java.lang.Object
This mixin triggers component event notifications when the attached component enters itsBeginRenderandAfterRenderrender phases. A common use of this is to handle the "afterRender" event to generate client-side JavaScript for content just rendered via aBlock(this is a common Ajax use case related to partial page rendering). Since AJAX requests don't trigger afterRender or beforeRender render phase events in the containing component or page, this mixin provides a way of accessing those events as component events.An example using the
Anycomponent within a zone:<div t:type="Zone" id="myZone"> <t:any t:mixins="RenderNotification"> <!-- zone content -> </div> </div>TheMarkupWriteris passed as the event context to your event handler method(s), so your corresponding component or page class might look like:void onBeginRenderFromMyZone(MarkupWriter writer) { writer.element("p"); writer.write("before item render"); writer.end(); } void onAfterRenderFromMyZone(MarkupWriter writer) { writer.element("p"); writer.write("after item render"); writer.end(); }As an alternative, see theTriggercomponent, which does something similar but as a component rather than a mixin.- Since:
