+ <interface name="ext_action_binder_v1" version="1">
+ <description summary="action binder">
+ 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

+ <description summary="sets the machine-readable trigger of a binding">
+ This setting is optional.
+ The trigger is a suggestion to the compositor, and the action should not rely

+
+ 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.
+
+ The trigger format is split into two fields, what kind of device triggers it, and a
+ general trigger string.
+
+ as of version 1 of this protocol, the following kinds are defined:
+ "sym": trigger is a combo of XKB key names
+ "mouse": trigger is button[1-9], mapped to their x11 values, (1=left, 2=middle, 3=right,
+ 4=scroll up, 5=scroll down, 6=scroll left, 7=scroll right, 8=back, 9=forward)
+ "switch": trigger on the format switch:state, where "lid" and "tablet" are valid switches
+ "gesture": trigger on the format gesture[:fingers][:direction] with the following gestures:
+ hold: 1-5 fingers, no direction
+ swipe: 3-5 fingers, up, down, left or right
+ pinch: 2-5 fingers, all above, inward, outward, clockwise, counterclockwise

+ Depending on the user configuration, an action can be either one_shot or
+ sustained. The client must handle all the three event types and either make
+ sense of them or ignore them properly.
+
+ one_shot actions are for events that don't have a defined "end", like a laptop
+ lid closing, or a gesture. The client should not expect to recieve a released or
+ ending event for that action.
+
+ sustained actions have a start and an end. after a 'pressed' event is sent, a
+ 'released' event should eventually be sent as well.
