Struct DragCancelEvent

Source

pub struct DragCancelEvent {
    pub start_state: PointerState,
    pub current_state: PointerState,
    pub button: Option<PointerButton>,
    pub pointer: PointerInfo,
    pub custom_data: Option<Rc<dyn Any>>,
}

Expand description

Event data for when a drag operation is cancelled.

Only sent to the element being dragged via DragSourceEvent::Cancel. Occurs when the drag is aborted (e.g., Escape key pressed, pointer left window, or pointer released without a valid drop target accepting the drop).

Fields§

§start_state: PointerState

The pointer state from when the drag started

§current_state: PointerState

Final pointer state

§button: Option<PointerButton>

Which button initiated the drag

§pointer: PointerInfo

Pointer identity

§custom_data: Option<Rc<dyn Any>>

Custom data passed from the drag source

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
