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
ObjectAn object with attribute name/configuration pairs.
-
values
ObjectAn 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
BooleanWhether 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.

()
private
Destructor logic for UI event infrastructure, invoked during Widget destruction.
_drawAxis
()

Draws an axis.
_filterAdHocAttrs
-
allAttrs
-
userVals
Parameters:
-
allAttrs
ObjectThe set of all attribute configurations for this instance. Attributes will be removed from this set, if they belong to the filtered class, so that by the time all classes are processed, allCfgs will be empty.
-
userVals
ObjectThe config object passed in by the user, from which adhoc attrs are to be filtered.
Returns:
_filterAttrCfgs

-
allCfgs
A helper method used when processing ATTRS across the class hierarchy during initialization. Returns a disposable object with the attributes defined for the provided class, extracted from the set of all attributes passed in.
Parameters:
Returns:
_filterUIEvent
-
evt
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.
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.

addAttr
-
name
-
config
-
lazy
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
StringThe name of the attribute.
-
config
ObjectAn 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:
addAttrs
-
cfgs
-
values
-
lazy
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
ObjectAn object with attribute name/configuration pairs.
-
values
ObjectAn 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
BooleanWhether 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:
addKey
-
value
Adds an array to the key hash.
Parameters:
-
value
ObjectIndicates what key to use in retrieving the array.
addTarget
-
o

fire
-
type
-
arguments
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.
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.
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.
Parameters:
-
type
String | ObjectThe 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:

[arg*]
Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.
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, or pass an array of event names as the first argument to subscribe to all listed events with the same callback.
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:
Returns:
once
-
type
-
fn
-
[context]
