Cancel

Description

This event is sent when pointer interaction is cancelled.

A PointerCancelEvent can trickle down or bubble up, but cannot be cancelled. Disabled elements won't receive this event by default.

See PointerEventBase<T0> to see how PointerCancelEvent relates to other pointer events.

Constructors

PointerCancelEvent Constructor. Avoid creating new event instances. Instead, use GetPooled() to get an instance from a pool of reusable event instances.

Protected Methods

Init Resets the event members to their initial values.

Inherited Members

Properties

bubbles Returns whether this event type bubbles up in the event propagation path.
dispatch Indicates whether the event is being dispatched to a visual element. An event cannot be redispatched while it being dispatched. If you need to recursively dispatch an event, it is recommended that you use a copy of the event.
imguiEvent The IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI.
isImmediatePropagationStopped Indicates whether StopImmediatePropagation() was called for this event.
isPropagationStopped Whether StopPropagation() was called for this event.
originalMousePosition The original mouse position of the IMGUI event, before it is transformed to the current target local coordinates.
pooled Whether the event is allocated from a pool of events.
propagationPhase The current propagation phase for this event.
target The target visual element that received this event. Unlike currentTarget, this target does not change when the event is sent to other elements along the propagation path.
timestamp The time when the event was created, in milliseconds.
tricklesDown Returns whether this event is sent down the event propagation path during the TrickleDown phase.
eventTypeId Retrieves the type ID for this event instance.
actionKey Gets a boolean value that indicates whether the platform-specific action key is pressed. True means the action key is pressed. False means it isn't.
altitudeAngle Gets the angle of the stylus relative to the surface, in radians
altKey Gets a boolean value that indicates whether the Alt key is pressed. True means the Alt key is pressed. False means it isn't.
azimuthAngle Gets the angle of the stylus relative to the x-axis, in radians.
button Gets a value that indicates which mouse button was pressed or released (if any) to cause this event: 0 is the left button, 1 is the right button, 2 is the middle button. A negative value indicates that no mouse button changed state during this event.
clickCount Gets the number of times the button was pressed.
commandKey Gets a boolean value that indicates whether the Windows/Cmd key is pressed. True means the Windows/Cmd key is pressed. False means it isn't.
ctrlKey Gets a boolean value that indicates whether the Ctrl key is pressed. True means the Ctrl key is pressed. False means it isn't.
currentTarget Gets the current target of the event.
deltaPosition Gets the difference between the pointer's position during the previous mouse event and its position during the current mouse event.
deltaTime Gets the amount of time that has elapsed since the last recorded change in pointer values, in seconds.
isPrimary Gets a boolean value that indicates whether the pointer is a primary pointer. True means the pointer is a primary pointer. False means it isn't.
localPosition Gets the pointer position in the current target's coordinate system.
modifiers Gets flags that indicate whether modifier keys (Alt, Ctrl, Shift, Windows/Cmd) are pressed.
penStatus Specifies the state of the pen. For example, whether the pen is in contact with the screen or tablet, whether the pen is inverted, and whether buttons are pressed. On macOS, penStatus will not reflect changes to button mappings.
pointerId Gets the identifier of the pointer that sent the event.
pointerType Gets the type of pointer that created the event.
position Gets the pointer position in the Screen or World coordinate system.
pressedButtons Gets a bitmask that describes the buttons that are currently pressed.
pressure Gets the amount of pressure currently applied by a touch.
radius Gets an estimate of the radius of a touch.
radiusVariance Gets the accuracy of the touch radius.
shiftKey Gets a boolean value that indicates whether the Shift key is pressed. True means the Shift key is pressed. False means it isn't.
tangentialPressure Gets the pressure applied to an additional pressure-sensitive control on the stylus.
tilt Specifies the angle of the pen relative to the X and Y axis respectively, in radians.
twist Gets the rotation of the stylus around its axis, in radians.

Public Methods

StopImmediatePropagation Immediately stops the propagation of the event. The event isn't sent to other elements along the propagation path. This method prevents other event handlers from executing on the current target.
StopPropagation Stops propagating this event. The event is not sent to other elements along the propagation path. This method does not prevent other event handlers from executing on the current target. If this method is called during the TrickleDown propagation phase, it will prevent default actions to be processed, such as an element getting focused as a result of a PointerDownEvent.
Dispose Implementation of IDispose.

PreDispatch

Static Methods

RegisterEventType Registers an event class to the event type system.
GetPooled Gets an event from the event pool. Use this function instead of creating new events. Events obtained using this method need to be released back to the pool. You can use Dispose() to release them.
TypeId Retrieves the type ID for this event instance.
GetPooled Gets an event from the event pool and initializes it with the given values. Use this function instead of creating new events. Events obtained using this method need to be released back to the pool. You can use Dispose() to release them.
