Properties

#events

Type EventDispatcher <AMEvent <this, IBaseObjectEvents>>

An EventDispatcher instance

4 inherited items

#clonedFrom

Type $type.Optional <this>Inherited from BaseObject

Reference to the original object this object was cloned from. We need to keep this so we can disassociate it from source object when this object is disposed.

#config

Type objectInherited from BaseObject

Use this property to set JSON-based config. When set, triggers processing routine, which will go through all properties, and try to apply values, create instances, etc.

Use this with caution, as it is a time-consuming process. It's used for initialchart setup only, not routine operations.

#id

Type $type.Optional <string>Inherited from BaseObject

Sets the user-defined id of the element.

#uid

Type stringInherited from BaseObject

Returns object's internal unique ID.

Methods

#constructor()

Returns BaseObjectEvents

Constructor

#copyFrom(source: this)

Returns void

Copies all parameters from another Sprite.

#dispatch(eventType: Key,
data?: any)

Returns void

Dispatches an event using own event dispatcher. Will automatically populate event data object with event type and target (this element).

It also checks if there are any handlers registered for this sepecific event.

#dispatchImmediately(eventType: Key,
data?: any)

Returns void

Works like dispatch, except event is triggered immediately, without waiting for the next frame cycle.

4 inherited items

Returns thisInherited from BaseObject

Makes a copy of this object and returns the clone. Try to avoid cloning complex objects like chart, create new instances if you need them.

#dispose()

Returns voidInherited from BaseObject

Destroys this object and all related data.

#getCurrentThemes()

Returns ITheme[]Inherited from BaseObject

Returns a list of themes that should be applied to this element. It could either be a list of themes set explicitly on this element, or system-wide.
