advertise offered mime type
Sent immediately after creating the wl_data_offer object. One
event per offered mime type.
Fields of Offer
notify the source-side available actions
This event indicates the actions offered by the data source. It
will be sent right after wl_data_device.enter, or anytime the source
side changes its offered actions through wl_data_source.set_actions.
Only available since version 3 of the interface
Fields of SourceActions
notify the selected action
This event indicates the action selected by the compositor after
matching the source/destination side actions. Only one action (or
none) will be offered here.
This event can be emitted multiple times during the drag-and-drop
operation in response to destination side action changes through
wl_data_offer.set_actions.
This event will no longer be emitted after wl_data_device.drop
happened on the drag-and-drop destination, the client must
honor the last action received, or the last preferred one set
through wl_data_offer.set_actions when handling an "ask" action.
Compositors may also change the selected action on the fly, mainly
in response to keyboard modifier changes during the drag-and-drop
operation.
The most recent action received is always the valid one. Prior to
receiving wl_data_device.drop, the chosen action may change (e.g.
due to keyboard modifiers being pressed). At the time of receiving
wl_data_device.drop the drag-and-drop destination must honor the
last action received.
Action changes may still happen after wl_data_device.drop,
especially on "ask" actions, where the drag-and-drop destination
may choose another action afterwards. Action changes happening
at this stage are always the result of inter-client negotiation, the
compositor shall no longer be able to induce a different action.
Upon "ask" actions, it is expected that the drag-and-drop destination
may potentially choose a different action and/or mime type,
based on wl_data_offer.source_actions and finally chosen by the
user (e.g. popping up a menu with the available options). The
final wl_data_offer.set_actions and wl_data_offer.accept requests
must happen before the call to wl_data_offer.finish.
Only available since version 3 of the interface
