methodprivatevirtual on_set_actions : [> `V3 ]t->dnd_actions:{Imports}1.Wl_data_device_manager.Dnd_action.t ->
unit
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.
