Variants

Offer

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.

Fields of Offer

mime_type: String

Destroy

destroy the data source

Destroy the data source.

This is a destructor, once sent this object cannot be used any longer.

SetActions

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.

Only available since version 3 of the interface

Fields of SetActions

dnd_actions: u32
