## Methods

### addEventListener

- addEventListener(type: string, listener: function, useCapture?: boolean, priority?: number, useWeakReference?: boolean): void

- Inherited from EventDispatcher.addEventListener

  - Defined in lib/openfl/events/EventDispatcher.d.ts:168

  Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event. You can register event listeners on all nodes in the display list for a specific type of event, phase, and priority.

  After you successfully register an event listener, you cannot change its priority through additional calls to `addEventListener()`. To change a listener's priority, you must first call `removeListener()`. Then you can register the listener again with the new priority level.

  Keep in mind that after the listener is registered, subsequent calls to `addEventListener()` with a different `type` or `useCapture` value result in the creation of a separate listener registration. For example, if you first register a listener with `useCapture` set to `true`, it listens only during the capture phase. If you call `addEventListener()` again using the same listener object, but with `useCapture` set to `false`, you have two separate listeners: one that listens during the capture phase and another that listens during the target and bubbling phases.

  You cannot register an event listener for only the target phase or the bubbling phase. Those phases are coupled during registration because bubbling applies only to the ancestors of the target node.

  If you no longer need an event listener, remove it by calling `removeEventListener()`, or memory problems could result. Event listeners are not automatically removed from memory because the garbage collector does not remove the listener as long as the dispatching object exists(unless the `useWeakReference` parameter is set to `true`).

  Copying an EventDispatcher instance does not copy the event listeners attached to it.(If your newly created node needs an event listener, you must attach the listener after creating the node.) However, if you move an EventDispatcher instance, the event listeners attached to it move along with it.

  If the event listener is being registered on a node while an event is being processed on this node, the event listener is not triggered during the current phase but can be triggered during a later phase in the event flow, such as the bubbling phase.

  If an event listener is removed from a node while an event is being processed on the node, it is still triggered by the current actions. After it is removed, the event listener is never invoked again(unless registered again for future processing).

  throws

    ArgumentError The `listener` specified is not a function.

  #### Parameters

  - ##### type: string

    The type of event.

  - ##### listener: function

    - - (event: object): void

      - #### Parameters

        - ##### event: object

        #### Returns void

  - ##### Optional useCapture: boolean

    Determines whether the listener works in the capture phase or the target and bubbling phases. If `useCapture` is set to `true`, the listener processes the event only during the capture phase and not in the target or bubbling phase. If `useCapture` is `false`, the listener processes the event only during the target or bubbling phase. To listen for the event in all three phases, call `addEventListener` twice, once with `useCapture` set to `true`, then again with `useCapture` set to `false`.

  - ##### Optional priority: number

    The priority level of the event listener. The priority is designated by a signed 32-bit integer. The higher the number, the higher the priority. All listeners with priority _n_ are processed before listeners of priority _n_-1. If two or more listeners share the same priority, they are processed in the order in which they were added. The default priority is 0.

  - ##### Optional useWeakReference: boolean

    Determines whether the reference to the listener is strong or weak. A strong reference(the default) prevents your listener from being garbage-collected. A weak reference does not.

                            Class-level member functions are not subject to
                            garbage collection, so you can set
                            `useWeakReference` to `true`
                            for class-level member functions without
                            subjecting them to garbage collection. If you set
                            `useWeakReference` to `true`
                            for a listener that is a nested inner function,
                            the function will be garbage-collected and no
                            longer persistent. If you create references to the
                            inner function(save it in another variable) then
                            it is not garbage-collected and stays
                            persistent.

  #### Returns void

### dispatchEvent

- dispatchEvent(event: Event): boolean

- Inherited from EventDispatcher.dispatchEvent

  - Defined in lib/openfl/events/EventDispatcher.d.ts:186

  Dispatches an event into the event flow. The event target is the EventDispatcher object upon which the `dispatchEvent()` method is called.

  throws

    Error The event dispatch recursion limit has been reached.

  #### Parameters

  - ##### event: Event

    The Event object that is dispatched into the event flow. If the event is being redispatched, a clone of the event is created automatically. After an event is dispatched, its `target` property cannot be changed, so you must create a new copy of the event for redispatching to work.

  #### Returns boolean

  A value of `true` if the event was successfully dispatched. A value of `false` indicates failure or that `preventDefault()` was called on the event.

### hasEventListener

- hasEventListener(type: string): boolean

- Inherited from EventDispatcher.hasEventListener

  - Defined in lib/openfl/events/EventDispatcher.d.ts:209

  Checks whether the EventDispatcher object has any listeners registered for a specific type of event. This allows you to determine where an EventDispatcher object has altered handling of an event type in the event flow hierarchy. To determine whether a specific event type actually triggers an event listener, use `willTrigger()`.

  The difference between `hasEventListener()` and `willTrigger()` is that `hasEventListener()` examines only the object to which it belongs, whereas `willTrigger()` examines the entire event flow for the event specified by the `type` parameter.

  When `hasEventListener()` is called from a LoaderInfo object, only the listeners that the caller can access are considered.

  #### Parameters

  - ##### type: string

    The type of event.

  #### Returns boolean

  A value of `true` if a listener of the specified type is registered; `false` otherwise.

### removeEventListener

- removeEventListener(type: string, listener: function, useCapture?: boolean): void

- Inherited from EventDispatcher.removeEventListener

  - Defined in lib/openfl/events/EventDispatcher.d.ts:227

  Removes a listener from the EventDispatcher object. If there is no matching listener registered with the EventDispatcher object, a call to this method has no effect.

  #### Parameters

  - ##### type: string

    The type of event.

  - ##### listener: function

    - - (event: object): void

      - #### Parameters

        - ##### event: object

        #### Returns void

  - ##### Optional useCapture: boolean

    Specifies whether the listener was registered for the capture phase or the target and bubbling phases. If the listener was registered for both the capture phase and the target and bubbling phases, two calls to `removeEventListener()` are required to remove both, one call with `useCapture()` set to `true`, and another call with `useCapture()` set to `false`.

  #### Returns void

### toString

- toString(): string

- Inherited from EventDispatcher.toString

  - Defined in lib/openfl/events/EventDispatcher.d.ts:230

  #### Returns string

### willTrigger

- willTrigger(type: string): boolean

- Inherited from EventDispatcher.willTrigger

  - Defined in lib/openfl/events/EventDispatcher.d.ts:253

  Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type. This method returns `true` if an event listener is triggered during any phase of the event flow when an event of the specified type is dispatched to this EventDispatcher object or any of its descendants.

  The difference between the `hasEventListener()` and the `willTrigger()` methods is that `hasEventListener()` examines only the object to which it belongs, whereas the `willTrigger()` method examines the entire event flow for the event specified by the `type` parameter.

  When `willTrigger()` is called from a LoaderInfo object, only the listeners that the caller can access are considered.

  #### Parameters

  - ##### type: string

    The type of event.

  #### Returns boolean

  A value of `true` if a listener of the specified type will be triggered; `false` otherwise.

### Static getDeviceAt

- getDeviceAt(index: number): GameInputDevice

- - Defined in lib/openfl/ui/GameInput.d.ts:18

  #### Parameters

  - ##### index: number

  #### Returns GameInputDevice
