Struct ExtDataControlDeviceV1

pub struct ExtDataControlDeviceV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

manage a data device for a seat

This interface allows a client to manage a seat’s selection.

When the seat is destroyed, this object becomes inert.

See also the Request enum for this interface.

Implementations

impl ExtDataControlDeviceV1

pub fn data_offer(&self, id: &ExtDataControlOfferV1)

introduce a new ext_data_control_offer

The data_offer event introduces a new ext_data_control_offer object, which will subsequently be used in either the ext_data_control_device.selection event (for the regular clipboard selections) or the ext_data_control_device.primary_selection event (for the primary clipboard selections). Immediately following the ext_data_control_device.data_offer event, the new data_offer object will send out ext_data_control_offer.offer events to describe the MIME types it offers.

pub fn selection(&self, id: Option<&ExtDataControlOfferV1>)

advertise new selection

The selection event is sent out to notify the client of a new ext_data_control_offer for the selection for this device. The ext_data_control_device.data_offer and the ext_data_control_offer.offer events are sent out immediately before this event to introduce the data offer object. The selection event is sent to a client when a new selection is set. The ext_data_control_offer is valid until a new ext_data_control_offer or NULL is received. The client must destroy the previous selection ext_data_control_offer, if any, upon receiving this event. Regardless, the previous selection will be ignored once a new selection ext_data_control_offer is received.

The first selection event is sent upon binding the ext_data_control_device object.

pub fn finished(&self)

this data control is no longer valid

This data control object is no longer valid and should be destroyed by the client.

pub fn primary_selection(&self, id: Option<&ExtDataControlOfferV1>)

advertise new primary selection

The primary_selection event is sent out to notify the client of a new ext_data_control_offer for the primary selection for this device. The ext_data_control_device.data_offer and the ext_data_control_offer.offer events are sent out immediately before this event to introduce the data offer object. The primary_selection event is sent to a client when a new primary selection is set. The ext_data_control_offer is valid until a new ext_data_control_offer or NULL is received. The client must destroy the previous primary selection ext_data_control_offer, if any, upon receiving this event. Regardless, the previous primary selection will be ignored once a new primary selection ext_data_control_offer is received.

If the compositor supports primary selection, the first primary_selection event is sent upon binding the ext_data_control_device object.

impl PartialEq<Weak<ExtDataControlDeviceV1>> for ExtDataControlDeviceV1

fn eq(&self, other: &Weak<ExtDataControlDeviceV1>) -> 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.
