Struct ContextRequestedEventArgs 

pub struct ContextRequestedEventArgs { /* private fields */ }

Provides event data for the context requested event.

Implementations

impl ContextRequestedEventArgs

pub fn new() -> Self

Creates args for a context request that has no position, e.g. one made with the keyboard.

pub fn from_pointer_event_args(pointer_event_args: &PointerEventArgs) -> Self

Creates args for a context request made with a pointer.

pub fn from_context_requested_event_args( context_requested_event_args: &ContextRequestedEventArgs, ) -> Self

Creates args from other context requested args, keeping the position.

pub fn try_get_position( &self, relative_to: Option<&InputElement>, ) -> Option<Point>

Gets the point on which the context was requested, relative to the specified element (or to the root when None).

Returns None if the context was not requested with a pointer, e.g. when it was requested with the keyboard.

pub fn is_holding(&self) -> bool

Whether the context was requested by holding a pointer down.

Internal in the reference, where the controls assembly sees it.

pub fn pointer_type(&self) -> Option<PointerType>

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 ContextRequestedEventArgs

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for ContextRequestedEventArgs

fn default() -> Self

Returns the “default value” for a type.

impl Deref for ContextRequestedEventArgs

type Target = RoutedEventArgs

The resulting type after dereferencing.

fn deref(&self) -> &RoutedEventArgs

Dereferences the value.

impl IRoutedEventArgs for ContextRequestedEventArgs

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 ContextRequestedEventArgs

const MARKUP: &'static MarkupType

The markup metadata of the type.
