_filterUIEvent

(
  • evt
)
Boolean private

This method is used to determine if we should fire the UI Event or not. The default implementation makes sure that for nested delegates (nested unrelated widgets), we don't fire the UI event listener more than once at each level.

<p>For example, without the additional filter, if you have nested widgets, each widget will have a delegate listener. If you click on the inner widget, the inner delegate listener's filter will match once, but the outer will match twice (based on delegate's design) - once for the inner widget, and once for the outer.</p>

Parameters:

Returns:

Boolean:

<p><p><p><p><p><p><p>true if it's OK to fire the custom UI event, false if not.</p></p></p></p></p></p></p>

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

<p> Adds an attribute with the provided configuration to the host object. </p> <p> The config argument object supports the following properties: </p>

<dl> <dt>value <Any></dt> <dd>The initial value to set on the attribute</dd>

<dt>valueFn <Function | String></dt> <dd> <p>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.</p>

<p>valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.</p> </dd>

<dt>readOnly <boolean></dt> <dd>Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.</dd>

<dt>writeOnce <boolean> or <string></dt> <dd> 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. <p>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)</p> </dd>

<dt>setter <Function | String></dt> <dd> <p>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 <a href="#property_Attribute.INVALID_VALUE">Attribute.INVALID_VALUE</a>, from the setter will prevent the value from being stored. </p>

<p>setter can also be set to a string, representing the name of the instance method to be used as the setter function.</p> </dd>

<dt>getter <Function | String></dt> <dd> <p> 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. </p>

<p>getter can also be set to a string, representing the name of the instance method to be used as the getter function.</p> </dd>

<dt>validator <Function | String></dt> <dd> <p> The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored. </p>

<p>validator can also be set to a string, representing the name of the instance method to be used as the validator function.</p> </dd>

<dt>lazyAdd <boolean></dt> <dd>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 <a href="#method_addAttrs">addAttrs</a> method.</dd>

</dl>

<p>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.</p>

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

Parameters:

  • name String

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>The name of the attribute.</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • config Object

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>An object with attribute configuration property/value pairs, specifying the configuration for the attribute.</p> <p><p> <strong>NOTE:</strong> 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. </p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • lazy Boolean

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

Returns:

Object:

<p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>A reference to the host object.</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • lazy Boolean

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>Whether or not to delay the intialization of these attributes until the first call to get/set.

fire

(
  • type
  • arguments
)
Boolean

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

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>The type of the event, or an object that contains a 'type' property.</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

Returns:

Boolean:

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

modifyAttr

(
  • name
  • config
)

Updates the configuration of an attribute which has already been added. <p> The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute: </p> <dl> <dt>readOnly;</dt> <dt>writeOnce;</dt> <dt>broadcast; and</dt> <dt>getter.</dt> </dl> <p> Note: New attributes cannot be added using this interface. New attributes must be added using addAttr, or an appropriate manner for a class which utilises Attributes (e.g. the ATTRS property in Base). </p>

Parameters:

  • name String

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>The name of the attribute whose configuration is to be updated.</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • config Object

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>An object with configuration property/value pairs, specifying the configuration properties to modify.</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

next

(
  • circular
)
Widget

Returns the Widget's next sibling.

Parameters:

  • circular Boolean

    <p><p><p><p><p><p><p>Boolean indicating if the parent's first child should be returned if the child has no next sibling.</p></p></p></p></p></p></p>

Returns:

Widget:

<p><p><p><p><p><p><p>Widget instance.</p></p></p></p></p></p></p>

on

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

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

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>The name of the event</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • fn Function

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>The callback to execute in response to the event</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • [context] Object optional

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>Override <code>this</code> object in callback</p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p></p>

  • [arg*] Any optional

    <p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p><p>0..n additional arguments to supply to the subscriber</p></p></p></p></p></p></p>
