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.

PointerMove

The pointer moved without a button change.

Fields

position: Point

Pointer position in logical pixels.

PointerDown

A pointer button was pressed.

Fields

position: Point

Pointer position in logical pixels.

button: PointerButton

Button that was pressed.

PointerUp

A pointer button was released.

Fields

position: Point

Pointer position in logical pixels.

button: PointerButton

Button that was released.

DoubleClick

A second primary click in quick succession, sent after its PointerUp.

Fields

position: Point

Pointer position in logical pixels.

PointerLeave

The pointer left the window or canvas.

Scroll

Wheel or trackpad scrolling, in logical pixels. Positive delta.y means the user scrolled up (content should move down), as on every platform.

Fields

position: Point

Pointer position in logical pixels.

delta: Point

Scroll distance in logical pixels on each axis.

KeyDown

A key was pressed (including auto-repeat).

Fields

key: Key

Key that was pressed.

modifiers: Modifiers

Modifier keys held at the time of the press.

KeyUp

A key was released.

Fields

key: Key

Key that was released.

modifiers: Modifiers

Modifier keys held at the time of the release.

FocusLost

The window or canvas lost keyboard focus.

Pinch

A pinch on a trackpad or Ctrl with the wheel: a zoom gesture.

Fields

position: Point

Pointer position in logical pixels.

delta: f32

How much larger the user asked for, relative to now: 0.02 is 2% larger, and a negative value is smaller.
