Enum gdk4::CrossingMode

#[non_exhaustive]
pub enum CrossingMode {
    Normal,
    Grab,
    Ungrab,
    GtkGrab,
    GtkUngrab,
    StateChanged,
    TouchBegin,
    TouchEnd,
    DeviceSwitch,
    // some variants omitted
}

Specifies the crossing mode for enter and leave events.

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.

Normal

crossing because of pointer motion.

Grab

crossing because a grab is activated.

Ungrab

crossing because a grab is deactivated.

GtkGrab

crossing because a GTK grab is activated.

GtkUngrab

crossing because a GTK grab is deactivated.

StateChanged

crossing because a GTK widget changed state (e.g. sensitivity).

TouchBegin

crossing because a touch sequence has begun, this event is synthetic as the pointer might have not left the surface.

TouchEnd

crossing because a touch sequence has ended, this event is synthetic as the pointer might have not left the surface.

DeviceSwitch

crossing because of a device switch (i.e. a mouse taking control of the pointer after a touch device), this event is synthetic as the pointer didn’t leave the surface.

Trait Implementations

impl Clone for CrossingMode

fn clone(&self) -> CrossingMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CrossingMode

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

Formats the value using the given formatter.

impl Display for CrossingMode

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

Formats the value using the given formatter.

impl<'a> FromValue<'a> for CrossingMode

type Checker = GenericValueTypeChecker<CrossingMode>

Value type checker.

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

Get the contained value from a Value.

impl Hash for CrossingMode

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 CrossingMode

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<CrossingMode> for CrossingMode

fn eq(&self, other: &CrossingMode) -> 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<CrossingMode> for CrossingMode

fn partial_cmp(&self, other: &CrossingMode) -> 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 ToValue for CrossingMode

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for CrossingMode

type Type = CrossingMode

Type to get the Type from.

impl Copy for CrossingMode
