Expand description

A trait for any object that has the data for a pointer event

Required Methods§

Source

fn pointer_id(&self) -> i32

Gets the unique identifier of the pointer causing the event.

Source

fn width(&self) -> i32

Gets the width (magnitude on the X axis), in CSS pixels, of the contact geometry of the pointer.

Source

fn height(&self) -> i32

Gets the height (magnitude on the Y axis), in CSS pixels, of the contact geometry of the pointer.

Source

fn pressure(&self) -> f32

Gets the normalized pressure of the pointer input in the range of 0 to 1,

Source

fn tangential_pressure(&self) -> f32

Gets the normalized tangential pressure of the pointer input (also known as barrel pressure or cylinder stress) in the range -1 to 1,

Source

fn tilt_x(&self) -> i32

Gets the plane angle (in degrees, in the range of -90 to 90) between the Y-Z plane and the plane containing both the transducer (e.g. pen stylus) axis and the Y axis.

Source

fn tilt_y(&self) -> i32

Gets the plane angle (in degrees, in the range of -90 to 90) between the X-Z plane and the plane containing both the transducer (e.g. pen stylus) axis and the X axis.

Source

fn twist(&self) -> i32

Gets the clockwise rotation of the pointer (e.g. pen stylus) around its major axis in degrees, with a value in the range 0 to 359.The clockwise rotation of the pointer (e.g. pen stylus) around its major axis in degrees, with a value in the range 0 to 359.
