Struct zng_app::view_process::raw_events::RawMouseWheelArgs

pub struct RawMouseWheelArgs {
    pub timestamp: DInstant,
    pub window_id: WindowId,
    pub device_id: DeviceId,
    pub delta: MouseScrollDelta,
    pub phase: TouchPhase,
    /* private fields */
}

Arguments for the RAW_MOUSE_WHEEL_EVENT.

Fields

timestamp: DInstant

Instant the event happened.

window_id: WindowId

Window that is hovered by the mouse.

device_id: DeviceId

Device that generated this event.

delta: MouseScrollDelta

Wheel motion delta, value is in pixels if the wheel is a touchpad.

phase: TouchPhase

Touch state if the device that generated the event is a touchpad.

Implementations

impl RawMouseWheelArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, delta: impl Into<MouseScrollDelta>, phase: impl Into<TouchPhase>, ) -> Self

New args from values that convert into the argument types.

pub fn now( window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, delta: impl Into<MouseScrollDelta>, phase: impl Into<TouchPhase>, ) -> Self

Arguments for event that happened now (INSTANT.now).
