Enum ViewportEvent 

pub enum ViewportEvent {
    PointerMoved {
        position: Vec2,
    },
    MouseButton {
        button: MouseButton,
        state: ButtonState,
    },
    Wheel {
        delta: Vec2,
        units: ScrollUnits,
    },
    Key {
        key: KeyCode,
        state: ButtonState,
        repeat: bool,
    },
    ModifiersChanged(Modifiers),
    PointerLeft,
    FocusLost,
}

A framework-agnostic 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 the lower-level path).

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.
