Method Detail

altitudeAngle

@JsProperty(name="altitudeAngle")
public float altitudeAngle()

azimuthAngle

@JsProperty(name="azimuthAngle")
public float azimuthAngle()

clientX

@JsProperty(name="clientX")
public double clientX()

The Touch.clientX read-only property returns the X coordinate of the touch point relative to the viewport, not including any scroll offset.

Touch.clientX - MDN, Touch Events – Level 2, Touch Events

clientY

@JsProperty(name="clientY")
public double clientY()

The Touch.clientY read-only property returns the Y coordinate of the touch point relative to the browser's viewport, not including any scroll offset.

Touch.clientY - MDN, Touch Events – Level 2, Touch Events

force

@JsProperty(name="force")
public float force()

The Touch.force read-only property returns the amount of pressure the user is applying to the touch surface for a Touch point.

See Also:

Touch.force - MDN, Touch Events – Level 2

identifier

@JsProperty(name="identifier")
public int identifier()

The Touch.identifier returns a value uniquely identifying this point of contact with the touch surface. This value remains consistent for every event involving this finger's (or stylus's) movement on the surface until it is lifted off the surface.

Touch.identifier - MDN, Touch Events – Level 2, Touch Events

pageX

@JsProperty(name="pageX")
public double pageX()

The Touch.pageX read-only property returns the X coordinate of the touch point relative to the viewport, including any scroll offset.

See Also:

Touch.pageX - MDN, Touch Events – Level 2, Touch Events

pageY

@JsProperty(name="pageY")
public double pageY()

The Touch.pageY read-only property returns the Y coordinate of the touch point relative to the viewport, including any scroll offset.

See Also:

Touch.pageY - MDN, Touch Events – Level 2, Touch Events

radiusX

@JsProperty(name="radiusX")
public float radiusX()

Returns the X radius of the ellipse that most closely circumscribes the area of contact with the touch surface. The value is in CSS pixels of the same scale as Touch.screenX.

See Also:

Touch.radiusX - MDN, Touch Events – Level 2

radiusY

@JsProperty(name="radiusY")
public float radiusY()

Returns the Y radius of the ellipse that most closely circumscribes the area of contact with the touch surface. The value is in CSS pixels of the same scale as Touch.screenX.

See Also:

Touch.radiusY - MDN, Touch Events – Level 2

rotationAngle

@JsProperty(name="rotationAngle")
public float rotationAngle()

Returns the rotation angle, in degrees, of the contact area ellipse defined by Touch.radiusX and Touch.radiusY. The value may be between 0 and 90. Together, these three values describe an ellipse that approximates the size and shape of the area of contact between the user and the screen. This may be a relatively large ellipse representing the contact between a fingertip and the screen or a small area representing the tip of a stylus, for example.

Touch.rotationAngle - MDN, Touch Events – Level 2

screenX

@JsProperty(name="screenX")
public double screenX()

Returns the X coordinate of the touch point relative to the screen, not including any scroll offset.

See Also:

Touch.screenX - MDN, Touch Events – Level 2, Touch Events

screenY

@JsProperty(name="screenY")
public double screenY()

Returns the Y coordinate of the touch point relative to the screen, not including any scroll offset.

See Also:

Touch.screenY - MDN, Touch Events – Level 2, Touch Events

target

@JsProperty(name="target")
 @Nonnull
public EventTarget target()

Returns the Element (EventTarget) on which the touch contact started when it was first placed on the surface, even if the touch point has since moved outside the interactive area of that element or even been removed from the document. Note that if the target element is removed from the document, events will still be targeted at it, and hence won't necessarily bubble up to the window or document anymore. If there is any risk of an element being removed while it is being touched, the best practice is to attach the touch listeners directly to the target.
