Detailed Description

Mouse 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, delta.y = 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.
