}

An input event generated by the integration.

This only covers events that egui cares about.

Variants

Copy

The integration detected a “copy” event (e.g. Cmd+C).

Cut

The integration detected a “cut” event (e.g. Cmd+X).

Text(String)

Text input, e.g. via keyboard or paste action.

When the user presses enter/return, do not send a Text (just Key::Enter).

Key

Fields of Key

key: Keypressed: boolmodifiers: Modifiers

PointerMoved(Pos2)

PointerButton

Fields of PointerButton

pos: Pos2button: PointerButtonpressed: boolmodifiers: Modifiers

The state of the modifier keys at the time of the event

PointerGone

The mouse left the screen, or the last/primary touch input disappeared.

This means there is no longer a cursor on the screen for hovering etc.

On touch-up first send PointerButton{pressed: false, …} followed by PointerLeft.

CompositionStart

IME composition start.

CompositionUpdate(String)

A new IME candidate is being suggested.

CompositionEnd(String)

IME composition ended with this final result.

Touch

Fields of Touch

device_id: TouchDeviceId

Hashed device identifier (if available; may be zero). Can be used to separate touches from different devices.

id: TouchId

Unique identifier of a finger/pen. Value is stable from touch down to lift-up

phase: TouchPhasepos: Pos2

Position of the touch (or where the touch was last detected)

force: f32

Describes how hard the touch device was pressed. May always be 0 if the platform does not support pressure sensitivity. The value is in the range from 0.0 (no pressure) to 1.0 (maximum pressure).

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl PartialEq<Event> for Event

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

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

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

This method tests for !=.
