Enum winit::MouseScrollDelta

pub enum MouseScrollDelta {
    LineDelta(f32, f32),
    PixelDelta(LogicalPosition),
}

Describes a difference in the mouse scroll wheel state.

Variants

LineDelta(f32, 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(LogicalPosition)

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.
