Struct SizeChangedEventArgs 

pub struct SizeChangedEventArgs { /* private fields */ }

Provides data specific to a SizeChanged event.

Implementations

impl SizeChangedEventArgs

pub fn with_event<T: ?Sized>(routed_event: &RoutedEvent<T>) -> Self

Creates args for a routed event.

pub fn with_event_and_source<T: ?Sized>( routed_event: &RoutedEvent<T>, source: impl Into<Nullable<FerroObject>>, ) -> Self

Creates args for a routed event with a source.

pub fn new<T: ?Sized>( routed_event: &RoutedEvent<T>, source: impl Into<Nullable<FerroObject>>, previous_size: Size, new_size: Size, ) -> Self

Creates args for a routed event with a source and the previous and new sizes.

pub fn height_changed(&self) -> bool

Whether the height of the new size is considered different to the previous size height.

This will take into account layout epsilon and will not be true if both heights are considered equivalent for layout purposes. Remember there can be small variations in the calculations between layout cycles due to rounding and precision even when the size has not otherwise changed.

pub fn new_size(&self) -> Size

The new size (or bounds) of the object.

pub fn previous_size(&self) -> Size

The previous size (or bounds) of the object.

pub fn width_changed(&self) -> bool

Whether the width of the new size is considered different to the previous size width.

See height_changed.

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>(&self, value: Option<&RoutedEvent<T>>)

where T: ?Sized,

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 SizeChangedEventArgs

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 SizeChangedEventArgs

fn default() -> Self

Returns the “default value” for a type.

impl Deref for SizeChangedEventArgs

type Target = RoutedEventArgs

The resulting type after dereferencing.

fn deref(&self) -> &RoutedEventArgs

Dereferences the value.

impl IRoutedEventArgs for SizeChangedEventArgs

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 SizeChangedEventArgs

const MARKUP: &'static MarkupType

The markup metadata of the type.
