Defaults to SelectListboxCfg. Type of the configuration object for this widget.
Creates a new instance of this widget. Please note that you should NOT override this constructor. Instead, override the init method, which is called at the end of the constructor once the instance is created.
The widget configuration to be used for this widget
instance. This widget configuration is usually created on the server by the javax.faces.render.Renderer for
this component.
All available items, including disabled options. These are not form elements, but the DOM elements presented to the user.
The configuration of this widget instance. Please note that
no property is guaranteed to be present, you should always check for undefined before accessing a property.
This is partly because the value of a property is not transmitted from the server to the client when it equals
the default.
Array of registered listeners invoked when this widget is destroyed. You should normally not use modify this directly, use addDestroyListener instead.
true if this many select element is disabled, false if enabled, undefined
if the state is not known.
DOM element of the input element used for entering a filter text, if filtering is enabled.
The filter that was selected and is currently used.
Map between the available filter types and the filter implementation.
The client-side ID of this widget, with all parent naming containers, such as
myForm:myWidget. This is also the ID of the container HTML element for this widget. In case the widget needs
multiple container elements (such as Paginator), this may also be an array if IDs.
The hidden INPUT or SELECT element.
All available items, excluding disabled options. These are not form elements, but the DOM elements presented to the user.
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.
A CSS selector for the container element (or elements, in case id is an array) of
this widget, This is usually an ID selector (that is properly escaped). You can select the container element or
elements like this: $(widget.jqId).
Container of the list element.
The element that contains the available items.
A list of the available OPTION elements of the hidden SELECT element.
Array of registered listeners invoked when this widget is refreshed. You should normally not use modify this directly, use addRefreshListener instead.
The name of the widget variables of this widget. The widget variable can be used to
access a widget instance by calling PF('myWidgetVar').
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.
A refresh listener to be registered.
Sets up all event listeners for this widget instance.
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="..." />.
The name of an event to call.
Additional configuration that is passed to the AJAX request for the server-side callback.
Implementation of a PrimeFaces.widget.SelectListbox.FilterFunction that matches the given option when it
contains the given search text.
Text of an option.
Value of the filter.
true when the text of the contains the filter value, or false otherwise.
Will be called after an AJAX request if the widget container will be detached.
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 this method gets called.
Please note that instead of overriding this method, you should consider adding a destroy listener instead via addDestroyListener. 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 just calls all destroy listeners.
Disables this input so that the user cannot enter a value anymore.
Enables this input so that the user can enter a value.
Implementation of a PrimeFaces.widget.SelectListbox.FilterFunction that matches the given option when it ends
with the given search text.
Text of an option.
Value of the filter.
true when the text of the options ends with the filter value, or false otherwise.
Filters the options of this select list box by the given search value.
Current value of the filter.
Each widget may have one or several behaviors attached to it. This method returns the callback function for the given event.
Note: Do not call the method directly, the recommended way to invoke a behavior is via callBehavior.
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.

<p:ajax event="name" actionListener="#{...}" onstart="..." />.
The name of an event for which to retrieve the behavior.
The behavior with the given name, or null if no such behavior
exists.
Each widget has got a container element, this method returns that container. This container element is usually also the element whose ID is the client-side ID of the JSF component.
The jQuery instance representing the main HTML container element of this widget.
Gets the closest parent form for this widget.
A JQuery instance that either contains the form when found, or an empty JQuery instance when the form could not be found.
Gets the closest parent form ID for this widget lazily so it can be used in AJAX requests.
Either the form ID or undefined if no form can be found.
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.

The name of an event to check.
true if this widget has the given behavior, false otherwise.
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
}
});
The widget configuration to be used for this widget instance.
This widget configuration is usually created on the server by the javax.faces.render.Renderer for this
component.
Checks if this widget is detached, ie whether the HTML element of this widget is currently contained within the DOM (the HTML body element). A widget may become detached during an AJAX update, and it may remain detached in case the update removed this component from the component tree.
true if this widget is currently detached, or false otherwise.
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.
The new widget configuration from the server.
The value as returned by the init method, which is often undefined.
Removes the widget's script block from the DOM. Currently, the ID of this script block consists of the
client-side ID of this widget with the prefix _s, but this is subject to change.
The client-side ID of the widget.

Finds and stores the filter function which is to be used for filtering the options of this select list box.
Implementation of a PrimeFaces.widget.SelectListbox.FilterFunction that matches the given option when it starts
with the given search text.
Text of an option.
Value of the filter.
true when the text of the options starts with the filter value, or false otherwise.
Unselects all items that are currently selected.
Unselect the given items. Does not change other selected items.
