Struct input::TouchArgs

pub struct TouchArgs {
    pub device: i64,
    pub id: i64,
    pub position_3d: [f64; 3],
    pub pressure_3d: [f64; 3],
    pub is_3d: bool,
    pub touch: Touch,
}

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 in 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.

position_3d: [f64; 3]

The touch position, normalized 0..1.

pressure_3d: [f64; 3]

The touch pressure vector, normalized 0..1.

is_3d: bool

Whether the touch is in 3D.

touch: Touch

The touch state.

Implementations

impl TouchArgs

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

Creates arguments for 2D touch.

pub fn new_3d(
