Touch arguments

The id might be reused for different touches that do not overlap in time.

• Coordinates are normalized to support both touch screens and trackpads
• Supports both 2D and 3D touch
• The pressure direction vector should have maximum length 1

For 2D touch the pressure is pointed the z direction. Use .pressure() to get the pressure magnitude.

Fields

device: i64

A unique identifier for touch device.

id: i64

A unique identifier for touch event.

x: f64

The x coordinate of the touch position, normalized 0..1.

y: f64

The y coordinate of the touch position, normalized 0..1.

z: f64

The z coordinate of the touch position, normalized 0..1.

px: f64

The x coordinate of the touch pressure direction.

py: f64

The y coordinate of the touch pressure direction.

pz: f64

The z coordinate of the touch pressure direction.

is_3d: bool

Whether the touch is in 3D.

touch: Touch

The touch state.

Methods

impl TouchArgs

fn new(
    device: i64,
    id: i64,
    pos: [f64; 2],
    pressure: f64,
    touch: Touch
) -> TouchArgs

Creates arguments for 2D touch.

fn new_3d(
    device: i64,
    id: i64,
    pos: [f64; 3],
    pressure: [f64; 3],
    touch: Touch
) -> TouchArgs

Creates arguments for 3D touch.

The pressure direction vector should have maximum length 1.

fn position(&self) -> [f64; 2]

The position of the touch in 2D.

fn position_3d(&self) -> [f64; 3]

The position of the touch in 3D.

fn pressure(&self) -> f64

The pressure magnitude, normalized 0..1.

fn pressure_3d(&self) -> [f64; 3]

The pressure vector in 3D.
