Struct WlDataDeviceManager

pub struct WlDataDeviceManager { /* private fields */ }

Available on crate feature wayland and Linux only.

data transfer interface

The wl_data_device_manager is a singleton global object that provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop. These mechanisms are tied to a wl_seat and this interface lets a client get a wl_data_device corresponding to a wl_seat.

Depending on the version bound, the objects created from the bound wl_data_device_manager object will have different requirements for functioning properly. See wl_data_source.set_actions, wl_data_offer.accept and wl_data_offer.finish for details.

This interface has no events.

Implementations

impl WlDataDeviceManager

pub fn create_data_source<U, D>( &self, qh: &QueueHandle<D>, udata: U, ) -> WlDataSource

where U: Send + Sync + 'static, D: Dispatch<WlDataSource, U> + 'static,

create a new data source

Create a new data source.

pub fn get_data_device<U, D>( &self, seat: &WlSeat, qh: &QueueHandle<D>, udata: U, ) -> WlDataDevice

where U: Send + Sync + 'static, D: Dispatch<WlDataDevice, U> + 'static,

create a new data device

pub fn release(&self)

destroy wl_data_device_manager

This request destroys the wl_data_device_manager. This has no effect on any other objects.

impl PartialEq<Weak<WlDataDeviceManager>> for WlDataDeviceManager

fn eq(&self, other: &Weak<WlDataDeviceManager>) -> 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.
