Struct ExtDataControlDeviceV1

pub struct ExtDataControlDeviceV1 { /* private fields */ }

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 Event enum for this interface.

Implementations

impl ExtDataControlDeviceV1

pub fn set_selection(&self, source: Option<&ExtDataControlSourceV1>)

copy data to the selection

This request asks the compositor to set the selection to the data from the source on behalf of the client.

The given source may not be used in any further set_selection or set_primary_selection requests. Attempting to use a previously used source triggers the used_source protocol error.

To unset the selection, set the source to NULL.

pub fn destroy(&self)

destroy this data device

Destroys the data device object.

pub fn set_primary_selection(&self, source: Option<&ExtDataControlSourceV1>)

copy data to the primary selection

This request asks the compositor to set the primary selection to the data from the source on behalf of the client.

The given source may not be used in any further set_selection or set_primary_selection requests. Attempting to use a previously used source triggers the used_source protocol error.

To unset the primary selection, set the source to NULL.

The compositor will ignore this request if it does not support primary selection.

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.
