Struct DragEndArgs

pub struct DragEndArgs {
    pub timestamp: DInstant,
    pub target: InteractionPath,
    pub applied: DragDropEffect,
    /* private fields */
}

Arguments for DRAG_END_EVENT.

Fields

timestamp: DInstant

Instant the event happened.

target: InteractionPath

Draggable widget that was dragging.

applied: DragDropEffect

Effect applied by the drop target on the data.

Is empty or a single flag.

Implementations

impl DragEndArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, target: impl Into<InteractionPath>, applied: impl Into<DragDropEffect>, ) -> DragEndArgs

New args from values that convert into the argument types.

Panics

Panics if the arguments are invalid.

pub fn try_new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, target: impl Into<InteractionPath>, applied: impl Into<DragDropEffect>, ) -> Result<DragEndArgs, Txt>

New args from values that convert into the argument types.

Returns an error if the constructed arguments are invalid.

pub fn now( target: impl Into<InteractionPath>, applied: impl Into<DragDropEffect>, ) -> DragEndArgs

Arguments for event that happened now (INSTANT.now).

Panics

Panics if the arguments are invalid.

pub fn try_now( target: impl Into<InteractionPath>, applied: impl Into<DragDropEffect>, ) -> Result<DragEndArgs, Txt>

Arguments for event that happened now (INSTANT.now).

Returns an error if the constructed arguments are invalid.

pub fn validate(&self) -> Result<(), Txt>

The applied field can only be empty or only have a single flag set.

pub fn assert_valid(&self)

Panics if the arguments are invalid.

impl DragEndArgs

pub fn was_dropped(&self) -> bool

Data was dropped on a valid target.

pub fn was_canceled(&self) -> bool

Stopped dragging without dropping on a valid drop target.

Trait Implementations

impl AnyEventArgs for DragEndArgs

fn clone_any(&self) -> Box<dyn AnyEventArgs>

Clone the event into a type erased box.

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

Access to dyn Any methods.

fn timestamp(&self) -> DInstant

Gets the instant this event happened.

fn delivery_list(&self, list: &mut UpdateDeliveryList)

Insert all targets of this event on the UpdateDeliveryList.

fn propagation(&self) -> &EventPropagationHandle

Propagation handle associated with this event instance.

impl Clone for DragEndArgs

fn clone(&self) -> DragEndArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DragEndArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl EventArgs for DragEndArgs

fn handle<F, R>(&self, handler: F) -> Option<R>

where F: FnOnce(&Self) -> R,

Calls handler and stops propagation if propagation is still allowed.
