Implementations§

§

impl DragAndDrop

pub fn set_payload<Payload>(ctx: &Context, payload: Payload)
where Payload: Any + Send + Sync,

Set a drag-and-drop payload.

This can be read by Self::payload until the pointer is released.

pub fn clear_payload(ctx: &Context)

Clears the payload, setting it to None.

pub fn payload<Payload>(ctx: &Context) -> Option<Arc<Payload>>
where Payload: Any + Send + Sync,

Retrieve the payload, if any.

Returns None if there is no payload, or if it is not of the requested type.

Returns Some both during a drag and on the frame the pointer is released (if there is a payload).

pub fn take_payload<Payload>(ctx: &Context) -> Option<Arc<Payload>>
where Payload: Any + Send + Sync,

Retrieve and clear the payload, if any.

Returns None if there is no payload, or if it is not of the requested type.

Returns Some both during a drag and on the frame the pointer is released (if there is a payload).

pub fn has_payload_of_type<Payload>(ctx: &Context) -> bool
where Payload: Any + Send + Sync,

Are we carrying a payload of the given type?

Returns true both during a drag and on the frame the pointer is released (if there is a payload).

pub fn has_any_payload(ctx: &Context) -> bool

Are we carrying a payload?

Returns true both during a drag and on the frame the pointer is released (if there is a payload).
