Constructors
- WheelEvent(String type, {Window? view, num deltaX = 0, num deltaY = 0, num deltaZ = 0, int deltaMode = 0, int detail = 0, int screenX = 0, int screenY = 0, int clientX = 0, int clientY = 0, int button = 0, bool canBubble = true, bool cancelable = true, bool ctrlKey = false, bool altKey = false, bool shiftKey = false, bool metaKey = false, EventTarget? relatedTarget}) factory
Properties
- altKey → bool read-onlyinherited
- bubbles → bool? read-onlyinherited
- cancelable → bool? read-onlyinherited
- client → Point<
num> read-onlyinherited - composed → bool? read-onlyinherited
- ctrlKey → bool read-onlyinherited
- currentTarget → EventTarget? read-onlyinherited
- dataTransfer → DataTransfer read-onlyinherited
- defaultPrevented → bool read-onlyinherited
- deltaMode → int read-only
- deltaX → num read-only
- The amount that is expected to scroll horizontally, in units determined by deltaMode.
- deltaY → num read-only
- The amount that is expected to scroll vertically, in units determined by deltaMode.
- deltaZ → num? read-only
- detail → int? read-onlyinherited
- eventPhase → int read-onlyinherited
- fromElement → Node? read-onlyinherited
- The nonstandard way to access the element that the mouse comes from in the case of a
mouseoverevent. - hashCode → int read-onlyinherited
- The hash code for this object.
- isTrusted → bool? read-onlyinherited
- layer → Point<
num> read-onlyinherited - matchingTarget → Element read-onlyinherited
- A pointer to the element whose CSS selector matched within which an event was fired. If this Event was not associated with any Event delegation, accessing this value will throw an UnsupportedError.
- metaKey → bool read-onlyinherited
- movement → Point<
num> read-onlyinherited - offset → Point<
num> read-onlyinherited - The coordinates of the mouse pointer in target node coordinates.
- page → Point<
num> read-onlyinherited - path → List<
EventTarget> read-onlyinherited - region → String? read-onlyinherited
- runtimeType → Type read-onlyinherited
- A representation of the runtime type of the object.
- screen → Point<
num> read-onlyinherited - shiftKey → bool read-onlyinherited
- sourceCapabilities → InputDeviceCapabilities? read-onlyinherited
- target → EventTarget? read-onlyinherited
- timeStamp → num? read-onlyinherited
- toElement → Node? read-onlyinherited
- The nonstandard way to access the element that the mouse goes to in the case of a
mouseoutevent. - type → String read-onlyinherited
- view → WindowBase? read-onlyinherited
