Struct RawMouseWheelEventArgs 

pub struct RawMouseWheelEventArgs { /* private fields */ }

A raw mouse wheel event.

Implementations

impl RawMouseWheelEventArgs

pub fn new( device: Rc<dyn IInputDevice>, timestamp: u64, root: Rc<dyn IInputRoot>, position: Point, delta: Vector, input_modifiers: RawInputModifiers, ) -> Self

Creates raw mouse wheel event args.

pub fn delta(&self) -> Vector

The amount the wheel was scrolled by.

Methods from Deref<Target = RawPointerEventArgs>

pub fn raw_pointer_id(&self) -> i64

The raw pointer identifier.

pub fn set_raw_pointer_id(&self, value: i64)

pub fn point(&self) -> RawPointerPoint

The pointer properties and position, in client DIPs.

pub fn set_point(&self, value: RawPointerPoint)

pub fn position(&self) -> Point

The mouse position, in client DIPs.

pub fn set_position(&self, value: Point)

pub fn type_(&self) -> RawPointerEventType

The type of the event.

pub fn set_type(&self, value: RawPointerEventType)

pub fn input_modifiers(&self) -> RawInputModifiers

The input modifiers.

pub fn set_input_modifiers(&self, value: RawInputModifiers)

pub fn intermediate_points(&self) -> Option<IntermediatePoints>

Points that were traversed by a pointer since the previous relevant event, only valid for Move and TouchUpdate.

pub fn set_intermediate_points(&self, value: Option<IntermediatePoints>)

pub fn platform_input_event_cookie(&self) -> Option<Rc<dyn Any>>

The platform’s opaque cookie for the input event.

pub fn set_platform_input_event_cookie(&self, value: Option<Rc<dyn Any>>)

pub fn input_hit_test_result( &self, ) -> (Option<Ref<InputElement>>, Option<Ref<InputElement>>)

The result of input hit testing the event: the element under the pointer and its first enabled ancestor. Set by the presentation source before the event is processed.

pub fn set_input_hit_test_result( &self, element: Option<Ref<InputElement>>, first_enabled_ancestor: Option<Ref<InputElement>>, )

Methods from Deref<Target = RawInputEventArgs>

pub fn device(&self) -> &Rc<dyn IInputDevice>

The associated device.

pub fn root(&self) -> &Rc<dyn IInputRoot>

The root from which the event originates.

pub fn handled(&self) -> bool

Whether the event was handled.

If an event is not marked handled after processing, this event will be returned to the windowing subsystem for further processing.

pub fn set_handled(&self, value: bool)

Marks the event as handled or unhandled.

pub fn timestamp(&self) -> u64

The timestamp associated with the event.

pub fn set_timestamp(&self, value: u64)

Sets the timestamp associated with the event.
