DeviceOrientationEvent class

A DeviceOrientationEvent object describes an event that provides information about the current orientation of the device as compared to the Earth coordinate frame. See Orientation and motion data explained for details.
@DomName('DeviceOrientationEvent')

class DeviceOrientationEvent extends Event native "DeviceOrientationEvent" {
 factory DeviceOrientationEvent(String type,
     {bool canBubble: true, bool cancelable: true, num alpha: 0, num beta: 0,
     num gamma: 0, bool absolute: false}) {
   var e = document.$dom_createEvent("DeviceOrientationEvent");
   e.$dom_initDeviceOrientationEvent(type, canBubble, cancelable, alpha, beta,
       gamma, absolute);
   return e;
 }

Constructors

factory DeviceOrientationEvent(String type, {bool canBubble: true, bool cancelable: true, num alpha: 0, num beta: 0, num gamma: 0, bool absolute: false}) #

factory DeviceOrientationEvent(String type,
   {bool canBubble: true, bool cancelable: true, num alpha: 0, num beta: 0,
   num gamma: 0, bool absolute: false}) {
 var e = document.$dom_createEvent("DeviceOrientationEvent");

Properties

final bool absolute #

This attribute's value is true if the orientation is provided as a difference between the device coordinate frame and the Earth coordinate frame; if the device can't detect the Earth coordinate frame, this value is false. Read only.
final bool absolute

final num alpha #

The current orientation of the device around the Z axis; that is, how far the device is rotated around a line perpendicular to the device. Read only.
final num alpha

final num beta #

The current orientation of the device around the X axis; that is, how far the device is tipped forward or backward. Read only.
final num beta

final bool bubbles #

inherited from Event
A boolean indicating whether the event bubbles up through the DOM or not.
final bool bubbles

final bool cancelable #

inherited from Event
A boolean indicating whether the event is cancelable.
final bool cancelable

bool cancelBubble #

inherited from Event
A boolean indicating whether the bubbling of the event has been canceled or not.
bool cancelBubble

final DataTransfer clipboardData #

inherited from Event
final DataTransfer clipboardData

final EventTarget currentTarget #

inherited from Event
EventTarget get currentTarget => _convertNativeToDart_EventTarget(this._get_currentTarget);

final bool defaultPrevented #

inherited from Event
Indicates whether or not event.preventDefault() has been called on the event.
final bool defaultPrevented

final int eventPhase #

inherited from Event
Indicates which phase of the event flow is being processed.
final int eventPhase

final num gamma #

The current orientation of the device around the Y axis; that is, how far the device is turned left or right. Read only.
Note: If the browser is not able to provide notification information, all values are 0.
final num gamma

final int hashCode #

inherited from Interceptor

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.

docs inherited from Object
int get hashCode => Primitives.objectHashCode(this);

final Type runtimeType #

inherited from Interceptor

A representation of the runtime type of the object.

docs inherited from Object
Type get runtimeType => getRuntimeType(this);

final EventTarget target #

inherited from Event
EventTarget get target => _convertNativeToDart_EventTarget(this._get_target);

final int timeStamp #

inherited from Event
The time that the event was created.
final int timeStamp

final String type #

inherited from Event
The name of the event (case-insensitive).
final String type

Operators

bool operator ==(other) #

inherited from Interceptor

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.

docs inherited from Object
bool operator ==(other) => identical(this, other);

Methods

dynamic noSuchMethod(Invocation invocation) #

inherited from Interceptor

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.

docs inherited from Object
dynamic noSuchMethod(Invocation invocation) {
 throw new NoSuchMethodError(
     this,
     _symbolToString(invocation.memberName),
     invocation.positionalArguments,
     _symbolMapToStringMap(invocation.namedArguments));
}

void preventDefault() #

inherited from Event
Cancels the event (if it is cancelable).
@DomName('Event.preventDefault')
@DocsEditable
void preventDefault() native;

void stopImmediatePropagation() #

inherited from Event
For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)
@DomName('Event.stopImmediatePropagation')
@DocsEditable
void stopImmediatePropagation() native;

void stopPropagation() #

inherited from Event
Stops the propagation of events further along in the DOM.
@DomName('Event.stopPropagation')
@DocsEditable
void stopPropagation() native;

String toString() #

inherited from Interceptor

Returns a string representation of this object.

docs inherited from Object
String toString() => Primitives.objectToString(this);

@DocsEditable
void $dom_initDeviceOrientationEvent(String type, bool bubbles, bool cancelable, num alpha, num beta, num gamma, bool absolute) native;

void $dom_initEvent(String eventTypeArg, bool canBubbleArg, bool cancelableArg) #

inherited from Event
Initializes the value of an Event created through the DocumentEvent interface.
@JSName('initEvent')
@DomName('Event.initEvent')
@DocsEditable
void $dom_initEvent(String eventTypeArg, bool canBubbleArg, bool cancelableArg) native;
