InputEvent class Null safety

The InputEvent is a common base class for MouseEvent and TouchEvent.

This makes it more convenient to use the same event listener for mouse and touch events. The fields that are the same in mouse and touch events are defined in the InputEvent class.

Example:

StageXL.stageOptions.inputEventMode = InputEventMode.MouseAndTouch;

var sprite = new Sprite();
sprite.onMouseDown.listen(onSpriteSelected);
sprite.onTouchBegin.listen(onSpriteSelected);

void onSpriteSelected(InputEvent inputEvent) {
  print("{inputEvent.localX}, {inputEvent.localY});
}

InputEvent(String type, bool bubbles, num localX, num localY, num stageX, num stageY, bool? altKey, bool? ctrlKey, bool? shiftKey)
Creates a new InputEvent.

Properties

altKey bool?
Indicates whether the Alt key is active (true) or inactive (false).
final
bubbles bool
Indicates whether an event is a bubbling event. If the event can bubble, this value is true; otherwise it is false. [...]
read-only, inherited
captures bool
Indicates whether an event is a capturing event.
read-only, inherited
ctrlKey bool?
Indicates whether the Ctrl key is active (true) or inactive (false).
final
currentTarget EventDispatcher?
The object that is actively processing the Event object with an event listener. [...]
read-only, inherited
eventPhase EventPhase
The current phase in the event flow. [...]
read-only, inherited
hashCode int
The hash code for this object. [...]

isDefaultPrevented bool

isImmediatePropagationStopped bool
Indicates if the propagation of this event has been stopped. [...]
read-only, inherited
isPropagationStopped bool
Indicates if the propagation of this event has been stopped. [...]
read-only, inherited
localX num
The x-coordinate at which the event occurred relative to the containing display object.
final
localY num
The y-coordinate at which the event occurred relative to the containing display object.
final
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
shiftKey bool?
Indicates whether the Shift key is active (true) or inactive (false).
final
stageX num
The x-coordinate of the input event relative to the stage.
final
stageY num
The y-coordinate of the input event relative to the stage.
final
target EventDispatcher?
The event target. [...]

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
preventDefault() → void
stopImmediatePropagation() → void
Prevents processing of any event listeners in the current node and any subsequent nodes in the event flow. [...]
inherited
stopPropagation() → void
Prevents processing of any event listeners in nodes subsequent to the current node in the event flow. [...]
inherited
toString() String
A string representation of this object. [...]

Static Properties

current InputEvent?
The mouse or touch event that is currently dispatched. The value is only set if the code is running in the context of a mouse or touch event propagation, otherwise the value is null.
