CustomEvent class
CustomEvent are events initialized by an application for any purpose. It's represented by the nsIDOMCustomEvent
interface, which extends the nsIDOMEvent
interface.
@DomName('CustomEvent')
class CustomEvent extends Event native "CustomEvent" {
factory CustomEvent(String type,
{bool canBubble: true, bool cancelable: true, Object detail}) {
final CustomEvent e = document.$dom_createEvent("CustomEvent");
e.$dom_initCustomEvent(type, canBubble, cancelable, detail);
return e;
}

bool cancelBubble
final EventTarget currentTarget #
EventTarget get currentTarget => _convertNativeToDart_EventTarget(this._get_currentTarget);
final bool defaultPrevented #
event.preventDefault()
has been called on the event.
final bool defaultPrevented
final int eventPhase #
final int eventPhase
final int hashCode #
Get a hash code for this object.
All objects have hash codes. Hash codes are guaranteed to be the
same for objects that are equal when compared using the equality
operator ==. Other than that there are no guarantees about
the hash codes. They will not be consistent between runs and
there are no distribution guarantees.
If a subclass overrides hashCode it should override the
equality operator as well to maintain consistency.
int get hashCode => Primitives.objectHashCode(this);
final Type runtimeType #
A representation of the runtime type of the object.
Type get runtimeType => getRuntimeType(this);
final EventTarget target #
EventTarget get target => _convertNativeToDart_EventTarget(this._get_target);
Operators
bool operator ==(other) #
The equality operator.
The default behavior for all Objects is to return true if and
only if this and
other are the same object.
If a subclass overrides the equality operator it should override
the hashCode method as well to maintain consistency.
bool operator ==(other) => identical(this, other);
Methods
dynamic noSuchMethod(Invocation invocation) #
noSuchMethod is invoked when users invoke a non-existant method
on an object. The name of the method and the arguments of the
invocation are passed to noSuchMethod in an Invocation.
If noSuchMethod returns a value, that value becomes the result of
the original invocation.
The default behavior of noSuchMethod is to throw a
noSuchMethodError.
dynamic noSuchMethod(Invocation invocation) {
throw new NoSuchMethodError(
this,
_symbolToString(invocation.memberName),
invocation.positionalArguments,
_symbolMapToStringMap(invocation.namedArguments));

String toString() #
Returns a string representation of this object.
String toString() => Primitives.objectToString(this);
void $dom_initCustomEvent(String typeArg, bool canBubbleArg, bool cancelableArg, Object detailArg) #
Initializes the event in a manner analogous to the similarly-named method in the DOM Events interfaces.
Parameters
type- The name of the event.
canBubble- A boolean indicating whether the event bubbles up through the DOM or not.
cancelable- A boolean indicating whether the event is cancelable.
detail- The data passed when initializing the event.
