Enum wry::application::event::MouseScrollDelta [−][src]
#[non_exhaustive]
pub enum MouseScrollDelta {
LineDelta(f32, f32),
PixelDelta(PhysicalPosition<f64>),
}
Expand description
Describes a difference in the mouse scroll wheel state.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
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>)
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.
