Implementations

impl WlDataDevice

pub fn data_offer(&self, id: &WlDataOffer)

introduce a new wl_data_offer

The data_offer event introduces a new wl_data_offer object, which will subsequently be used in either the data_device.enter event (for drag-and-drop) or the data_device.selection event (for selections). Immediately following the data_device_data_offer event, the new data_offer object will send out data_offer.offer events to describe the mime types it offers.

pub fn enter(
    &self,
    serial: u32,
    surface: &WlSurface,
    x: f64,
    y: f64,
    id: Option<&WlDataOffer>
)

initiate drag-and-drop session

This event is sent when an active drag-and-drop pointer enters a surface owned by the client. The position of the pointer at enter time is provided by the x and y arguments, in surface-local coordinates.

pub fn leave(&self)

end drag-and-drop session

This event is sent when the drag-and-drop pointer leaves the surface and the session ends. The client must destroy the wl_data_offer introduced at enter time at this point.

pub fn motion(&self, time: u32, x: f64, y: f64)

drag-and-drop session motion

This event is sent when the drag-and-drop pointer moves within the currently focused surface. The new position of the pointer is provided by the x and y arguments, in surface-local coordinates.

pub fn drop(&self)

end drag-and-drop session successfully

The event is sent when a drag-and-drop operation is ended because the implicit grab is removed.

The drag-and-drop destination is expected to honor the last action received through wl_data_offer.action, if the resulting action is “copy” or “move”, the destination can still perform wl_data_offer.receive requests, and is expected to end all transfers with a wl_data_offer.finish request.

If the resulting action is “ask”, the action will not be considered final. The drag-and-drop destination is expected to perform one last wl_data_offer.set_actions request, or wl_data_offer.destroy in order to cancel the operation.

pub fn selection(&self, id: Option<&WlDataOffer>)

advertise new selection

The selection event is sent out to notify the client of a new wl_data_offer for the selection for this device. The data_device.data_offer and the data_offer.offer events are sent out immediately before this event to introduce the data offer object. The selection event is sent to a client immediately before receiving keyboard focus and when a new selection is set while the client has keyboard focus. The data_offer is valid until a new data_offer or NULL is received or until the client loses keyboard focus. Switching surface with keyboard focus within the same client doesn’t mean a new selection will be sent. The client must destroy the previous selection data_offer, if any, upon receiving this event.

Trait Implementations

impl AsRef<Resource<WlDataDevice>> for WlDataDevice

fn as_ref(&self) -> &Resource<Self>

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for WlDataDevice

fn clone(&self) -> WlDataDevice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WlDataDevice

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

Formats the value using the given formatter.

impl From<Resource<WlDataDevice>> for WlDataDevice

fn from(value: Resource<Self>) -> Self

Converts to this type from the input type.

impl Interface for WlDataDevice

type Request = Request

Set of requests associated to this interface

type Event = Event

Set of events associated to this interface

const NAME: &'static str = "wl_data_device"

Name of this interface

const VERSION: u32 = 3u32

Maximum supported version of this interface

fn c_interface() -> *const wl_interface

impl PartialEq<WlDataDevice> for WlDataDevice

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

This method tests for self and other values to be equal, and is used by ==.

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

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