Struct piston::TouchArgs [−][src]
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.
