Struct pugl_sys::Scroll

pub struct Scroll {
    pub dx: f64,
    pub dy: f64,
    pub modifiers: Modifiers,
}

A mouse wheel scroll event

The scroll distance is expressed in "lines", an arbitrary unit that corresponds to a single tick of a detented mouse wheel. For example, dy = 1.0 scrolls 1 line up. Some systems and devices support finer resolution and/or higher values for fast scrolls, so programs should handle any value gracefully.

Fields

dx: f64

horizontal scroll distance

dy: f64

vertical scroll distance

modifiers: Modifiers
