        position: Vec2,
    },
    MouseButton {
        button: MouseButton,
        state: ButtonState,

    ModifiersChanged(Modifiers),
    PointerLeft,
    FocusLost,
    Character(char),
    TrackpadRotate(f32),
}

An event delivered to the viewport input pipeline.

Host applications translate their native windowing events into ViewportEvent values and push them to super::controller::OrbitCameraController (or super::viewport_input::ViewportInput for direct input handling).

Variants

PointerMoved

The pointer moved to the given viewport-local position.

Fields

position: Vec2

Viewport-local position in logical pixels, origin at top-left.

MouseButton

A mouse button was pressed or released.

Fields

button: MouseButton

Which button changed state.

state: ButtonState

New button state.

Wheel

The scroll wheel moved.

Fields

delta: Vec2

Scroll delta. Positive Y = scroll up / zoom in (conventional).

units: ScrollUnits

Whether the delta is in lines or pixels.

Key

A keyboard key changed state.

Fields

key: KeyCode

Which key changed state.

state: ButtonState

New key state.

repeat: bool

True if the event is a key-repeat (key held down).

ModifiersChanged(Modifiers)

Modifier key state changed.

PointerLeft

The pointer left the viewport area.

FocusLost

The viewport lost keyboard focus.

Character(char)

A character was typed (Unicode).

Only push this event when the manipulation controller is active (ManipulationController::is_active()) to avoid swallowing other keypresses. The library filters the character stream to digits, ., and - before passing it to the numeric input buffer.

TrackpadRotate(f32)

Two-finger trackpad rotation gesture.

delta is the change in angle this event, in radians. Positive = counter-clockwise (matches winit’s RotationGesture convention, converted from degrees to radians by the host).

Platform-specific

Only emitted on macOS (and iOS). Silently unused on Windows and Linux.

Trait Implementations
