Variants

Offer

Fields

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.

Destroy

destroy the data source

Destroy the data source.

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

SetActions

Fields

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.

Only available since version 3 of the interface
