This interface is designed to allow any application to bind
an action.
An action is an arbitrary couple of a namespace and a name describing the
wanted behaviour. These two strings are not meant to be user-visible.
Some namespaces are well-known and shared by applications while each
application can have its own namespaces for internal actions.
It is possible to have the same action in several namespaces, e.g. to
allow application-specific bindings in addition to global actions.
It is left to the compositor to determine which client will get events.
The choice can be based on policy, heuristic, user configuration, or any
other mechanism that may be relevant.
Here are some examples of dispatching choice: all applications, last
focused, user-defined preference order, latest fullscreened application.
This interface is exposed as global
The client no longer wants to receive events for any action.
The client no longer wants to receive events for this binding.
Sets the namespace:name of the binding. This a kind of action.
This description may be used by the compositor to render a ui for bindings.
The trigger is a suggestion to the compositor, and the action should not rely
to being set to that specific trigger.
The client does not know which trigger was actually set, but when a binding is
bound, it recieves from the compositor a human readable string describing the trigger,
if any, so it could show it in a ui.
Bind an action to the object. this is a one-time request.
After calling bind, either the "bound" or "rejected" event is sent.
Subsequent calls to bind should be ignored.
If no action has been set for the binding, the error "invalid_action" is raised.
After the compositor processes a bind request, if the action was
bound to this binding, it calls this event to notify the client of the result.
After the compositor processes a bind request, if the binding was
rejected, it calls this event to notify the client of the result.
This event may be sent after a binding was bound, should the compositor
want to remove the binding.
After this event, the binding is destroyed and can't be used anymore.
Depending on the user configuration, an action can be either one-off or
sustained. The client must handle all the three event types and either make
sense of them or ignore them properly.
This event is sent when actions are triggered.
If a binding would trigger both triggered and started events, the
started event must be sent first.
