EventListener

# GdomeSmartDOM::EventListener

The EventListener interface is the primary method for handling events. Users implement the EventListener interface and register their listener on an EventTarget using the AddEventListener method. The users should also remove their EventListener from its EventTarget after they have completed using the listener. When a Node is copied using the cloneNode method the EventListeners attached to the source Node are not attached to the copied Node. If the user wishes the same EventListeners to be added to the newly created copy the user must add them manually.

Default Constructor
EventListener(GdomeEventListener* = 0)
Creates a smart pointer for the Gdome element whose pointer is passed as an argument. The user should never pass a non-null pointer to this constructor.

Copy and Cast Constructors
EventListener(const EventListener&)
These constructors can be used to copy a smart pointer or to downcast it. If the downcasting is not possible, the resulting smart pointer will be null.

Copy Operator
EventListener& operator=(const EventListener&)

Equality
bool operator==(const EventListener&) const bool operator!=(const EventListener&) const
Two smart pointers are equal if they point to the same Gdome object.

Methods
void handleEvent(const Event& evt) const
Parameters: evt The Event contains contextual information about the event. It also contains the stopPropagation and preventDefault methods which are used in determining the event's flow and default action. Description: This method is called whenever an event occurs of the type for which the EventListener interface was registered.
