axis source types

Describes the source types for axis events. This indicates to the client how an axis event was physically generated; a client may adjust the user interface accordingly. For example, scroll events from a “finger” source may be in a smooth coordinate space with kinetic scrolling whereas a “wheel” source may be in discrete steps of a number of lines.

The “continuous” axis source is a device generating events in a continuous coordinate space, but using something other than a finger. One example for this source is button-based scrolling where the vertical motion of a device is converted to scroll events while a button is held down.

The “wheel tilt” axis source indicates that the actual device is a wheel but the scroll event is not caused by a rotation but a (usually sideways) tilt of the wheel.

Variants

Wheel = 0

a physical wheel rotation

Finger = 1

finger on a touch surface

Continuous = 2

continuous coordinate space

WheelTilt = 3

a physical wheel tilt

Trait Implementations

impl Clone for AxisSource

fn clone(&self) -> AxisSource

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AxisSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<AxisSource> for u32

fn from(enum_value: AxisSource) -> Self

Converts to this type from the input type.

impl PartialEq for AxisSource

fn eq(&self, other: &AxisSource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u32> for AxisSource

type Error = TryFromPrimitiveError<AxisSource>

The type returned in the event of a conversion error.

fn try_from(number: u32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for AxisSource

const NAME: &'static str = "AxisSource"

type Primitive = u32

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for AxisSource

impl Eq for AxisSource

impl StructuralPartialEq for AxisSource
