Struct PinchEventArgs 

pub struct PinchEventArgs { /* private fields */ }

Provides data for the pinch gesture event.

Implementations

impl PinchEventArgs

pub fn new(scale: f64, scale_origin: Point) -> Self

Creates pinch event args with a scale and its origin.

pub fn with_angle( scale: f64, scale_origin: Point, angle: f64, angle_delta: f64, ) -> Self

Creates pinch event args with a scale, its origin and the angle of the gesture.

pub fn scale(&self) -> f64

The scale of the pinch relative to its start.

pub fn scale_origin(&self) -> Point

The origin of the scale.

pub fn angle(&self) -> f64

The angle of the pinch gesture, in degrees.

A pinch gesture is the movement of two pressed points closer together. This property is the measured angle of the line between those two points. Remember zero degrees is a line pointing up.

pub fn angle_delta(&self) -> f64

The difference from the previous and current pinch angle.

The value includes the sign of rotation: positive for clockwise, negative counterclockwise.

Methods from Deref<Target = RoutedEventArgs>

pub fn handled(&self) -> bool

Whether the routed event has already been handled.

Once handled, the event keeps travelling along its route but is only delivered to handlers registered for handled events too.

pub fn set_handled(&self, value: bool)

Marks the routed event as handled or unhandled.

pub fn routed_event(&self) -> Option<RoutedEvent>

The routed event associated with these args.

pub fn set_routed_event<T: ?Sized>(&self, value: Option<&RoutedEvent<T>>)

Sets the routed event associated with these args.

pub fn route(&self) -> RoutingStrategies

The routing strategy currently being applied to the event.

pub fn set_route(&self, value: RoutingStrategies)

Sets the routing strategy currently being applied to the event.

pub fn source(&self) -> Option<Ref<FerroObject>>

The object that raised the event.

pub fn set_source(&self, value: impl Into<Nullable<FerroObject>>)

Sets the object that raised the event.

pub fn is_source(&self, object: &FerroObject) -> bool

Whether object is the source of the event (C# e.Source == object).

Trait Implementations

impl Clone for PinchEventArgs

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Deref for PinchEventArgs

type Target = RoutedEventArgs

The resulting type after dereferencing.

fn deref(&self) -> &RoutedEventArgs

Dereferences the value.

impl IRoutedEventArgs for PinchEventArgs

fn as_routed_event_args(&self) -> &RoutedEventArgs

The base routed event args: the routing state of the event.

fn query_args(&self, type_id: TypeId) -> Option<&dyn Any>

Returns the args viewed as the args type identified by type_id, if the args are of that type or of a type derived from it.

fn is_args_type(type_id: TypeId) -> bool

Whether this args type is the args type identified by type_id or is derived from it.

fn share(&self) -> Rc<dyn IRoutedEventArgs>

A shared handle to these args: what untyped code (a handler wired up by markup) is given, since a borrow cannot be held in an untyped value. The handle refers to the live args: the state handlers change (handled, the source, a cancel flag, ..) is shared with them.

impl MarkupTyped for PinchEventArgs

const MARKUP: &'static MarkupType

The markup metadata of the type.
