Enum MouseScrollDelta

Source

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

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(f32, f32)

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.
