Describes a difference in the mouse scroll wheel position.

Variants

Lines

Fields

x: f64

The horizontal scroll distance. Negative values indicate scrolling left, and positive values indicate scrolling right.

y: f64

The vertical scroll distance. Negative values indicate scrolling down, and positive values indicate scrolling up.

z: f64

The forward/backward scroll distance, supported on some 3D mice.

Number of lines or rows to scroll in each direction. The y field represents the vertical scroll direction on a typical mouse wheel.

Pixels

Fields

x: f64

The horizontal scroll distance. Negative values indicate scrolling left, and positive values indicate scrolling right.

y: f64

The vertical scroll distance. Negative values indicate scrolling down, and positive values indicate scrolling up.

z: f64

The forward/backward scroll distance, supported on some 3D mice.

Number of pixels to scroll in each direction. Scroll events are expressed in pixels if supported by the device (eg. a touchpad) and platform. The y field represents the vertical scroll direction on a typical mouse wheel.

Pages

Fields

x: f64

The horizontal scroll distance. Negative values indicate scrolling left, and positive values indicate scrolling right.
