Struct DragEventArgs 

pub struct DragEventArgs { /* private fields */ }

Provides data for the drag-and-drop events.

Implementations

impl DragEventArgs

pub fn new( routed_event: Option<&RoutedEvent<DragEventArgs>>, data_transfer: Rc<dyn IDataTransfer>, target: Ref<Interactive>, target_location: Point, key_modifiers: KeyModifiers, ) -> Self

Creates drag event args. target_location is the location of the pointer in the coordinates of target.

pub fn drag_effects(&self) -> DragDropEffects

The effects of the operation. A handler sets them to what the target accepts.

pub fn set_drag_effects(&self, value: DragDropEffects)

Sets the effects of the operation.

pub fn data_transfer(&self) -> &Rc<dyn IDataTransfer>

The data being dragged.

pub fn key_modifiers(&self) -> KeyModifiers

The key modifiers held down during the event.

pub fn get_position(&self, relative_to: &Visual) -> Point

Gets the position of the pointer relative to a visual.

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 DragEventArgs

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 DragEventArgs

type Target = RoutedEventArgs

The resulting type after dereferencing.

fn deref(&self) -> &RoutedEventArgs

Dereferences the value.

impl IKeyModifiersEventArgs for DragEventArgs

fn key_modifiers(&self) -> KeyModifiers

The key modifiers associated with this event.

impl IRoutedEventArgs for DragEventArgs

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 DragEventArgs

const MARKUP: &'static MarkupType

The markup metadata of the type.
