Struct WlDataSource

pub struct WlDataSource { /* private fields */ }

Available on crate feature wayland and Linux only.

offer to transfer data

The wl_data_source object is the source side of a wl_data_offer. It is created by the source client in a data transfer and provides a way to describe the offered data and a way to respond to requests to transfer the data.

See also the Event enum for this interface.

Implementations

impl WlDataSource

pub fn offer(&self, mime_type: String)

add an offered mime type

This request adds a mime type to the set of mime types advertised to targets. Can be called several times to offer multiple types.

pub fn destroy(&self)

destroy the data source

Destroy the data source.

pub fn set_actions(&self, dnd_actions: DndAction)

set the available drag-and-drop actions

Sets the actions that the source side client supports for this operation. This request may trigger wl_data_source.action and wl_data_offer.action events if the compositor needs to change the selected action.

The dnd_actions argument must contain only values expressed in the wl_data_device_manager.dnd_actions enum, otherwise it will result in a protocol error.

This request must be made once only, and can only be made on sources used in drag-and-drop, so it must be performed before wl_data_device.start_drag. Attempting to use the source other than for drag-and-drop will raise a protocol error.

impl PartialEq<Weak<WlDataSource>> for WlDataSource

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