Uses

Extends Widget

Defined in: panel/js/panel.js:14

Module: panel

Available since 3.4.0

A basic Panel Widget, which can be positioned based on Page XY co-ordinates and is stackable (z-index support). It also provides alignment and centering support and uses a standard module format for it's content, with header, body and footer section support. It can be made modal, and has functionality to hide and focus on different events. The header and footer sections can be modified to allow for button support.

Methods

`_addAttrs`

(

cfgs
values
lazy

)

private

Inherited from AttributeCore: attribute/js/AttributeCore.js:854

Implementation behind the public addAttrs method.

This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

`_addLazyAttr`

(

name
[lazyCfg]

)

private

Inherited from AttributeCore: attribute/js/AttributeCore.js:360

Finishes initializing an attribute which has been lazily added.

Parameters:

name Object

The name of the attribute
[lazyCfg] Object optional

Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

`_addOutOfOrder`

(

name
cfg

)

private

Inherited from AttributeCore: attribute/js/AttributeCore.js:527

Utility method used by get/set to add attributes encountered out of order when calling addAttrs().

For example, if:

this.addAttrs({
     foo: {
         setter: function() {
            // make sure this bar is available when foo is added
            this.get("bar");
         }
     },
     bar: {
         value: ...
     }
});

Parameters:

name String

attribute name
cfg Object

attribute configuration

`_addShimResizeHandlers`

() private

Inherited from WidgetStack: widget-stack/js/Widget-Stack.js:329

Parameters:

node Node

The section Node to be updated.
children Node | NodeList | String

The new content Node, NodeList or String to be added to section Node provided.
where String

Optional. Either WidgetStdMod.AFTER, WidgetStdMod.BEFORE or WidgetStdMod.REPLACE. If not provided, the content will replace existing content in the Node.

`addAttr`

(

name
config
lazy

)

Object chainable

Inherited from AttributeCore: attribute/js/AttributeCore.js:157

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>

The initial value to set on the attribute

valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>

Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.

writeOnce <boolean> or <string>

Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>

Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

name String

The name of the attribute.
config Object

An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.
lazy Boolean

(optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object:

A reference to the host object.

`addAttrs`

(

cfgs
values
lazy

)

Object chainable

Inherited from AttributeCore: attribute/js/AttributeCore.js:823

Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

cfgs Object

An object with attribute name/configuration pairs.
values Object

An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy Boolean

Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

Returns:

Object:

A reference to the host object.

`addButton`

(

button
[section="footer"]
[index]

)

chainable

Inherited from WidgetButtons: widget-buttons/js/widget-buttons.js:284

Available since 3.4.0

Adds a button to this widget.

The new button node will have the Y.Plugin.Button plugin applied, be added to this widget's buttons, and rendered in the specified section at the specified index (or end of the section when no index is provided). If the section does not exist, it will be created.

This fires the buttonsChange event and adds the following properties to the event facade:

button: The button node or config object to add.
section: The WidgetStdMod section (header/body/footer) where the button will be added.
index: The index at which the button will be in the section.
src: "add"

Note: The index argument will be passed to the Array splice() method, therefore a negative value will insert the button that many items from the end. The index property on the buttonsChange event facade is the index at which the button was added.

Parameters:

button Node | Object | String

The button to add. This can be a Y.Node instance, config Object, or String name for a predefined button on the BUTTONS prototype property. When a config Object is provided, it will be merged with any defaults provided by any srcNode and/or a button with the same name defined on the BUTTONS property. The following are the possible configuration properties beyond what Node plugins accept by default:
- [action] Function | String optional
  
  The default handler that should be called when the button is clicked. A String name of a Function that exists on the context object can also be provided. Note: Specifying a set of events will override this setting.
- [classNames] String | String[] optional
  
  Additional CSS classes to add to the button node.
- [context=this] Object optional
  
  Context which any events or action should be called with. Defaults to this, the widget. Note: e.target will access the button node in the event handlers.
- [disabled=false] Boolean optional
  
  Whether the button should be disabled.
- [events="click"] String | Object optional
  
  Event name, or set of events and handlers to bind to the button node. See: Y.Node.on(), this value is passed as the first argument to on().
- [isDefault=false] Boolean optional
  
  Whether the button is the default button.
- [label] String optional
  
  The visible text/value displayed in the button.
- [name] String optional
  
  A name which can later be used to reference this button. If a button is defined on the BUTTONS property with this same name, its configuration properties will be merged in as defaults.
- [section] String optional
  
  The WidgetStdMod section (header, body, footer) where the button should be added.
- [srcNode] Node optional
  
  An existing Node to use for the button, default values will be seeded from this node, but are overriden by any values specified in the config object. By default a new <button> node will be created.
- [template] String optional
  
  A specific template to use when creating a new button node (e.g. "<a />"). Note: Specifying a srcNode will overide this.
[section="footer"] String optional

The WidgetStdMod section (header/body/footer) where the button should be added. This takes precedence over the button.section configuration property.
[index] Number optional

The index at which the button should be inserted. If not specified, the button will be added to the end of the section. This value is passed to the Array splice() method, therefore a negative value will insert the button that many items from the end.

It determines the height of the widgets bounding box, based on it's configured height value, and sets the height of the provided section to fill out any space remaining after the other standard module section heights have been accounted for.

NOTE: This method is not designed to work if an explicit height has not been set on the Widget, since for an "auto" height Widget, the heights of the header/body/footer will drive the height of the Widget.

Parameters:

node Node

The node which should be resized to fill out the height of the Widget bounding box. Should be a standard module section node which belongs to the widget.

`fire`

(

type
arguments

)

Boolean

Inherited from EventTarget: event-custom/js/event-target.js:673

Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters.

The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object.

If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

type String | Object

The type of the event, or an object that contains a 'type' property.
arguments Object*

an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

Returns:

Boolean:

True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

`focus`

() chainable

Inherited from Widget: widget/js/Widget.js:659

Causes the Widget to receive the focus by setting the "focused" attribute to "true".

EventHandle

Inherited from EventTarget: event-custom/js/event-target.js:188

Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.

 this.on("change", this._onChange, this);

Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name.

To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback.

 this.on({
     "attrChange" : this._onAttrChange,
     "change"     : this._onChange
 });

You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback.

 this.on([ "change", "attrChange" ], this._onChange);

Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

type String

The name of the event
fn Function

The callback to execute in response to the event
[context] Object optional

Override this object in callback

The collection is an Object which contains an Array of Y.Nodes for every WidgetStdMod section (header, body, footer) which has one or more buttons. All button nodes have the Y.Plugin.Button plugin applied.

This attribute is very flexible in the values it will accept. buttons can be specified as a single Array, or an Object of Arrays keyed to a particular section.

All specified values will be normalized to this type of structure:

{
    header: [...],
    footer: [...]
}

A button can be specified as a Y.Node, config Object, or String name for a predefined button on the BUTTONS prototype property. When a config Object is provided, it will be merged with any defaults provided by a button with the same name defined on the BUTTONS property.

See addButton() for the detailed list of configuration properties.

For convenience, a widget's buttons will always persist and remain rendered after header/body/footer content updates. Buttons should be removed by updating this attribute or using the removeButton() method.

Default: {}

Fires event `buttonsChange`

Fires when the value for the configuration attribute buttons is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

  If setting a property within the attribute's value, the name of the sub-attribute property being set.

`zIndex`

Number

Inherited from WidgetStack: widget-stack/js/Widget-Stack.js:78

The z-index to apply to the Widgets boundingBox. Non-numerical values for zIndex will be converted to 0

Default: 0

Fires event `zIndexChange`

Fires when the value for the configuration attribute zIndex is changed. You can listen for the event using the on method if you wish to be notified before the attribute's value has changed, or using the after method if you wish to be notified after the attribute's value has changed.

Parameters:

e EventFacade
An Event Facade object with the following attribute-specific properties added:
- prevVal Any
  The value of the attribute, prior to it being set.
- newVal Any
  The value the attribute is to be set to.
- attrName String
  The name of the attribute being set.
- subAttrName String
  If setting a property within the attribute's value, the name of the sub-attribute property being set.

Events

`destroy`

Inherited from BaseObservable: base/js/BaseObservable.js:163

Lifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.

Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).

Event Payload:

e EventFacade

Event object

`init`

Inherited from BaseObservable: base/js/BaseObservable.js:62

Lifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.

Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).

Event Payload:

e EventFacade

Event object, with a cfg property which refers to the configuration object passed to the constructor.

`render`

Inherited from Widget: widget/js/Widget.js:539

Lifecycle event for the render phase, fired prior to rendering the UI for the widget (prior to invoking the widget's renderer method).

Subscribers to the "on" moment of this event, will be notified before the widget is rendered.

Subscribers to the "after" moment of this event, will be notified after rendering is complete.

Event Payload:

e EventFacade

The Event Facade

`widget:contentUpdate`

Inherited from Widget: widget/js/Widget.js:397

Notification event, which widget implementations can fire, when they change the content of the widget. This event has no default behavior and cannot be prevented, so the "on" or "after" moments are effectively equivalent (with on listeners being invoked before after listeners).

Event Payload:

e EventFacade

The Event Facade
