Properties

Readonly animationProgress

animationProgress: number

A value between [-1, 0] indicates an animation progress from the current page to the previous page. A value between [0, 1] indicating an animation progress from the current page to the next page.

The animationProgress may be different from the pointer movement. This is because the animation may use an easing curve to look more natural.

A value of zero means no swiping progress, i.e. showing current page/spread. A value of -1 means showing the previous page/spread. A value of 1 means showing the next page/spread.

Readonly cancelable

cancelable: boolean

If this event's default action is cancelable. See respective engine event for its definition of default action.

Readonly defaultPrevented

defaultPrevented: boolean

If this event's default action has been canceled/prevented by a call to preventDefault()

Readonly deltaX

deltaX: number

The total X movement from the pointer start position in pixels.

A positive number means that the pointer is moving to the right. A negative number means that the pointer is moving to the left.

Readonly deltaY

deltaY: number

The total Y movement from the pointer start position in pixels.

A positive number means that the pointer is moving downwards. A negative number means that the pointer is moving upwards.

Readonly immediatePropagationStopped

immediatePropagationStopped: boolean

True if stopImmediatePropagation() was called on this event.

A positive number means that the pointer is moving to the right. A negative number means that the pointer is moving to the left.

Readonly relativeDeltaClientY

relativeDeltaClientY: number

The total Y movement relative to the window height. Typically a number between 0 and 1.
