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.

Delete

the window manager has requested that the toplevel surface be hidden or destroyed, usually when the user clicks on a special icon in the title bar.

MotionNotify

the pointer (usually a mouse) has moved.

ButtonPress

a mouse button has been pressed.

ButtonRelease

a mouse button has been released.

KeyPress

a key has been pressed.

KeyRelease

a key has been released.

EnterNotify

the pointer has entered the surface.

LeaveNotify

the pointer has left the surface.

FocusChange

the keyboard focus has entered or left the surface.

ProximityIn

an input device has moved into contact with a sensing surface (e.g. a touchscreen or graphics tablet).

ProximityOut

an input device has moved out of contact with a sensing surface.

DragEnter

the mouse has entered the surface while a drag is in progress.

DragLeave

the mouse has left the surface while a drag is in progress.

DragMotion

the mouse has moved in the surface while a drag is in progress.

DropStart

a drop operation onto the surface has started.

Scroll

the scroll wheel was turned

GrabBroken

a pointer or keyboard grab was broken.

TouchBegin

A new touch event sequence has just started.

TouchUpdate

A touch event sequence has been updated.

TouchEnd

A touch event sequence has finished.

TouchCancel

A touch event sequence has been canceled.

TouchpadSwipe

A touchpad swipe gesture event, the current state is determined by its phase field.

TouchpadPinch

A touchpad pinch gesture event, the current state is determined by its phase field.

PadButtonPress

A tablet pad button press event.

PadButtonRelease

A tablet pad button release event.

PadRing

A tablet pad axis event from a “ring”.

PadStrip

A tablet pad axis event from a “strip”.

PadGroupMode

A tablet pad group mode change.

TouchpadHold

Available on crate feature v4_8 only.

A touchpad hold gesture event, the current state is determined by its phase field. Since: 4.6

Trait Implementations

impl Clone for EventType

fn clone(&self) -> EventType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EventType

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

Formats the value using the given formatter.

impl Display for EventType

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

Formats the value using the given formatter.

impl From<EventType> for Value

fn from(v: EventType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for EventType

type Checker = GenericValueTypeChecker<EventType>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for EventType

type ParamSpec = ParamSpecEnum

type SetValue = EventType

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for EventType

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 EventType

fn cmp(&self, other: &EventType) -> 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<EventType> for EventType

fn eq(&self, other: &EventType) -> 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 EventType

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 EventType

type Type = EventType

Type to get the Type from.

impl Copy for EventType
