Expand description

How a device changed, with what the framework takes of that change.

Variants§

Add

The device started being tracked, such as the mouse coming into the view.

Remove

The device is no longer tracked.

Hover

It moved without touching, with buttons held, such as a pen’s barrel button.

Fields

§buttons: i64

Down

It touched, or its first button went down, with buttons held.

Fields

§buttons: i64

Move

It moved while touching, or the buttons it holds changed, to buttons.

Fields

§buttons: i64

Up

It stopped touching, or its last button was released, with buttons still held.

Fields

§buttons: i64

Cancel

The system took its press away, with buttons held.

Fields

§buttons: i64

Scroll

A wheel or a trackpad scrolled by delta, in physical pixels, positive towards the content’s end.

Fields

§delta: [f64; 2]

ScrollInertiaCancel

A touch stopped the system’s own scrolling momentum.

Scale

A zoom by scale, such as a browser’s for a wheel turned with Control held.

Fields

§scale: f64

PanZoomStart

A trackpad gesture, panning, zooming and rotating together, started.

PanZoomUpdate

The gesture so far, each the total since it started: pan in physical pixels, scale from 1.0, and rotation in radians, clockwise, from 0.0.

Fields

§pan: [f64; 2]

§scale: f64

§rotation: f64

PanZoomEnd

The gesture ended.
