Enum gdk4::NotifyType

#[non_exhaustive]
pub enum NotifyType {
    Ancestor,
    Virtual,
    Inferior,
    Nonlinear,
    NonlinearVirtual,
    Unknown,
}

Specifies the kind of crossing for enter and leave events.

See the X11 protocol specification of LeaveNotify for full details of crossing event generation.

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.

Ancestor

the surface is entered from an ancestor or left towards an ancestor.

Virtual

the pointer moves between an ancestor and an inferior of the surface.

Inferior

the surface is entered from an inferior or left towards an inferior.

Nonlinear

the surface is entered from or left towards a surface which is neither an ancestor nor an inferior.

NonlinearVirtual

the pointer moves between two surfaces which are not ancestors of each other and the surface is part of the ancestor chain between one of these surfaces and their least common ancestor.

Unknown

an unknown type of enter/leave event occurred.

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NotifyType

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

Formats the value using the given formatter.

impl From<NotifyType> for Value

fn from(v: NotifyType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for NotifyType

type Checker = GenericValueTypeChecker<NotifyType>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for NotifyType

type ParamSpec = ParamSpecEnum

type SetValue = NotifyType

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for NotifyType

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 NotifyType

fn cmp(&self, other: &NotifyType) -> 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 NotifyType

fn eq(&self, other: &NotifyType) -> 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.

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.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for NotifyType

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 NotifyType

type Type = NotifyType

Type to get the Type from.

impl Copy for NotifyType
