Defaults to VerticalTreeCfg. 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.
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.
The DOM element for the tree container.
When multiple nodes are selected, the selected node on which the user clicked most recently.
Array of registered listeners invoked when this widget is destroyed. You should normally not use modify this directly, use addDestroyListener instead.
List of parameter describing the drag & drop operations.
The DOM element for the filter input field that lets the user search the tree.
The set-timeout timer ID of the timer for the filter delay.
DOM element of the node which is currently focused, if any.
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.
A list of row keys for rows that are not valid drag sources.
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).
Target of the context menu, when a context menu is used.
Array of registered listeners invoked when this widget is refreshed. You should normally not use modify this directly, use addRefreshListener instead.
The set-interval time ID of the timer for scrolling.
Form element that holds the current scroll state.
DOM element of the hidden form element that holds the list of selected nodes.
List of nodes which are currently selected. Each item is the row key of a selected node.
For drag&drop, whether the shift is pressed.
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.

A sub class may perform any setup related to registering event handlers in this method, such as listening to mouse clicks or keyboard presses.
Sets up all event listeners for keyboard interactions.
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.
When this tree has got selectable nodes with checkboxes, selects the given checkbox. Does nothing 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.

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="..." />.

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
<p:ajax event="name" actionListener="#{...}" onstart="..." />.
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
}
});

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.
