Struct DragHandle

pub struct DragHandle(/* private fields */);

Represents dragging data.

Drop all clones of this handle to cancel the drag operation.

Implementations

impl DragHandle

pub fn dummy() -> DragHandle

New handle to nothing.

pub fn perm(self)

Drops the handle but does not cancel the drag operation.

The drag data stays alive until the user completes or cancels the operation.

pub fn is_permanent(&self) -> bool

If another handle has called perm.

If true operation will run to completion.

pub fn cancel(self)

Drops the handle and forces operation the cancel.

pub fn is_canceled(&self) -> bool

If another handle has called cancel.

pub fn downgrade(&self) -> WeakDragHandle

Create a weak handle.

Trait Implementations

impl Clone for DragHandle

fn clone(&self) -> DragHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DragHandle

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

Formats the value using the given formatter.

impl Hash for DragHandle

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DragHandle

fn eq(&self, other: &DragHandle) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
