Enum gdk4::AxisUse

#[non_exhaustive]
pub enum AxisUse {
    Ignore,
    X,
    Y,
    DeltaX,
    DeltaY,
    Pressure,
    Xtilt,
    Ytilt,
    Wheel,
    Distance,
    Rotation,
    Slider,
}

Defines how device axes are interpreted by GTK.

Note that the X and Y axes are not really needed; pointer devices report their location via the x/y members of events regardless. Whether X and Y are present as axes depends on the GDK backend.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ignore

the axis is ignored.

X

the axis is used as the x axis.

Y

the axis is used as the y axis.

DeltaX

the axis is used as the scroll x delta

DeltaY

the axis is used as the scroll y delta

Pressure

the axis is used for pressure information.

Xtilt

the axis is used for x tilt information.

Ytilt

the axis is used for y tilt information.

Wheel

the axis is used for wheel information.

Distance

the axis is used for pen/tablet distance information

Rotation

the axis is used for pen rotation information

Slider

the axis is used for pen slider information

Trait Implementations

impl Clone for AxisUse

fn clone(&self) -> AxisUse

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AxisUse

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

Formats the value using the given formatter.

impl From<AxisUse> for Value

fn from(v: AxisUse) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for AxisUse

type Checker = GenericValueTypeChecker<AxisUse>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for AxisUse

type ParamSpec = ParamSpecEnum

type SetValue = AxisUse

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: AxisUse) -> ParamSpecEnumBuilder<'_, AxisUse>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for AxisUse

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for AxisUse

fn cmp(&self, other: &AxisUse) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for AxisUse

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for AxisUse

fn partial_cmp(&self, other: &AxisUse) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for AxisUse

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for AxisUse

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for AxisUse

type Type = AxisUse

Type to get the Type from.

impl Copy for AxisUse

impl Eq for AxisUse

impl StructuralPartialEq for AxisUse
