multiple container elements (such as Paginator), this may also be an array if IDs.
The jQuery instance of the container element of this widget. In case id is an array, it will contain multiple elements. Please note that some widgets have got not DOM elements at all, in this case this will be an empty jQuery instance.

this widget, This is usually an ID selector (that is properly escaped). You can select the container element or
elements like this: $(widget.jqId).

Callback that is invoked when the widget may possibly have become visible.
Should return true when the widget was rendered, or false when the widget still needs to be rendered
later.
Lets you register a listener that is called before the component is destroyed.
When an AJAX call is made and this component is updated, the DOM element is replaced with the newly rendered content. When the element is removed from the DOM by the update, the DOM element is detached from the DOM and all destroy listeners are called. This makes it possible to add listeners from outside the widget code.
If you call this method twice with the same listener, it will be registered twice and later also called twice.
Note that for this to work, you must not override the destroy method; or if you do, call super.
Also, after this widget was detached is done, all destroy listeners will be unregistered.
A destroy listener to be registered.
When an AJAX call is made and this component is updated, the DOM element is replaced with the newly rendered content. However, no new instance of the widget is created. Instead, after the DOM element was replaced, all refresh listeners are called. This makes it possible to add listeners from outside the widget code.
If you call this method twice with the same listener, it will be registered twice and later also called twice.
Note that for this to work, you must not override the refresh method; or if you do, call super.
Also, after the refresh is done, all refresh listeners will be deregistered. If you added the listeners from
within this widget, consider adding the refresh listeners not only in the init method, but also again in
the refresh method after calling super.

Each widget may have one or several behaviors attached to it. This method calls all attached behaviors for the given event name. In case no such behavior exists, this method does nothing and returns immediately.
A behavior is a way for associating client-side scripts with UI components that opens all sorts of possibilities, including client-side validation, DOM and style manipulation, keyboard handling, and more. When the behavior is triggered, the configured JavaScript gets executed.
Behaviors are often, but not necessarily, AJAX behavior. When triggered, it initiates a request the server
and processes the response once it is received. This enables several features such as updating or replacing
elements dynamically. You can add an AJAX behavior via
<p:ajax event="name" actionListener="#{...}" onstart="..." />.

A behavior is a way for associating client-side scripts with UI components that opens all sorts of possibilities, including client-side validation, DOM and style manipulation, keyboard handling, and more. When the behavior is triggered, the configured JavaScript gets executed.
Behaviors are often, but not necessarily, AJAX behavior. When triggered, it initiates a request the server

Each widget may have one or several behaviors attached to it. This method checks whether this widget has got at least one behavior associated with given event name.
A behavior is a way for associating client-side scripts with UI components that opens all sorts of possibilities, including client-side validation, DOM and style manipulation, keyboard handling, and more. When the behavior is triggered, the configured JavaScript gets executed.
Behaviors are often, but not necessarily, AJAX behavior. When triggered, it initiates a request the server
and processes the response once it is received. This enables several features such as updating or replacing
elements dynamically. You can add an AJAX behavior via

A widget class should not declare an explicit constructor, the default constructor provided by this base widget should be used. Instead, override this initialize method which is called after the widget instance was constructed. You can use this method to perform any initialization that is required. For widgets that need to create custom HTML on the client-side this is also the place where you should call your render method.
Please make sure to call the super method first before adding your own custom logic to the init method:
PrimeFaces.widget.MyWidget = PrimeFaces.widget.BaseWidget.extend({
init: function(cfg) {
this._super(cfg);
// custom initialization
}
});

Removes the cloned table header and create a new clone.
Used in ajax updates, reloads the widget configuration.
When an AJAX call is made and this component is updated, the DOM element is replaced with the newly rendered content. However, no new instance of the widget is created. Instead, after the DOM element was replaced, this method is called with the new widget configuration from the server. This makes it possible to persist client-side state during an update, such as the currently selected tab.
Please note that instead of overriding this method, you should consider adding a refresh listener instead via addRefreshListener. This has the advantage of letting you add multiple listeners, and makes it possible to add additional listeners from code outside this widget.
By default, this method calls all refresh listeners, then reinitializes the widget by calling the init
method.
