Examples of IAjaxCallListener

org.apache.wicket.ajax.attributes.IAjaxCallListener
Interface used to listen at the most important points when Wicket performs an Ajax callback.
Ajax call listeners are potential contributors to the page header by implementing {@link org.apache.wicket.markup.html.IComponentAwareHeaderContributor}. E.g. the JavaScript used by the listener may depend on some JavaScript library, by implementing {@link org.apache.wicket.markup.html.IComponentAwareHeaderContributor} interfacethey can assure it will be loaded. @since 6.0
