Enum winit::event::MouseScrollDelta[−][src]

pub enum MouseScrollDelta {
    LineDelta(f32, f32),
    PixelDelta(PhysicalPosition<f64>),
}

Expand description

Describes a difference in the mouse scroll wheel state.

Variants

`LineDelta(f32, f32)`

Tuple Fields

0: f32

1: f32

Amount in lines or rows to scroll in the horizontal and vertical directions.

Positive values indicate movement forward (away from the user) or rightwards.

`PixelDelta(PhysicalPosition<f64>)`

Tuple Fields

0: PhysicalPosition<f64>

Amount in pixels to scroll in the horizontal and vertical direction.

Scroll events are expressed as a PixelDelta if supported by the device (eg. a touchpad) and platform.
