Provided Methods

fn offer(&mut self, evqh: &mut EventLoopHandle, client: &Client, resource: &WlDataSource, 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.

fn destroy(&mut self, evqh: &mut EventLoopHandle, client: &Client, resource: &WlDataSource)

destroy the data source

Destroy the data source.

This is a destructor, you cannot send events to this object once this method is called.

fn set_actions(&mut self, evqh: &mut EventLoopHandle, client: &Client, resource: &WlDataSource, dnd_actions: u32)

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.
