Defaults to SplitButtonCfg
. 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.
Number of concurrent active Ajax requests.
The DOM element for the main button.
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.
The DOM element for the filter input field
The current filter function.
A map of all flter functions. The key is the name of the filter function.
Unbind callback for the hide overlay handler.
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 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)
.
The DOM element for the additional buttons actions.
The DOM element for the button that triggers the overlay panel with the additional buttons actions.
The prefix shared ny the different IDs of the components of this widget.
The DOM element for the container of the additional buttons actions.
The DOM elements for the individual additional button actions.
Array of registered listeners invoked when this widget is refreshed. You should normally not use modify this directly, use addRefreshListener instead.
Unbind callback for the resize handler.
Unbind callback for the scroll handler.
Handler for CSS transitions used by this widget.
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.
Align the overlay panel with the additional buttons actions.
Sets up all event listeners required by this widget.
Sets up the event listeners for filtering the available buttons actions via a search field.
Sets up all panel event listeners
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.
A filter function that takes a value and a search and returns true if the value contains the search term.
Value to be filtered
Filter or search term to apply.
true
if the given value contains the search term, 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 button so that the user cannot press the button anymore.
Enables this button so that the user can press the button.
A filter function that takes a value and a search and returns true if the value ends with the search term.
Value to be filtered
Filter or search term to apply.
true
if the given value ends with the search term, or false
otherwise.
Filters the overlay panel with the additional buttons actions, leaving only the buttons that match the given search term.
Search term for filtering.
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.
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 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.
Callback that is invoked when the enter key is pressed. When overlay panel with the additional buttons actions is shown, activates the selected buttons action. Otherwise, opens the overlay panel.
Keyboard event of the enter press.
Callback that is invoked when the escape key is pressed while the overlay panel with the additional buttons actions is shown. Hides that overlay panel.
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.

Highlights the previous button action, usually when the user navigates via the keyboard arrows.
Keyboard arrow event that caused the previous item to be highlighted.
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.
