Enum gdk::NotifyType

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

Specifies the kind of crossing for EventCrossing.

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 window is entered from an ancestor or left towards an ancestor.

Virtual

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

Inferior

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

Nonlinear

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

NonlinearVirtual

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

Unknown

an unknown type of enter/leave event occurred.

const 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 Display for NotifyType

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

Formats the value using the given formatter.

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 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,

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.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<NotifyType> for NotifyType

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

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

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

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

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

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

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

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

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