voidzwp_tablet_pad_ring_v2_t::angle(doubledegrees,boolpost=true)
angle changed
Parametersdegrees the current angle in degrees
Sent whenever the angle on a ring changes.
The angle is provided in degrees clockwise from the logical north of the ring in the pad's current
rotation.

voidzwp_tablet_pad_ring_v2_t::frame(uint32_ttime,boolpost=true)
end of a ring event sequence
Parameterstime timestamp with millisecond granularity
Indicates the end of a set of ring events that logically belong together. A client is expected to
accumulate the data in all events within the frame before proceeding.
All wp_tablet_pad_ring events before a wp_tablet_pad_ring.frame event belong logically together. For
example, on termination of a finger interaction on a ring the compositor will send a
wp_tablet_pad_ring.source event, a wp_tablet_pad_ring.stop event and a wp_tablet_pad_ring.frame event.
A wp_tablet_pad_ring.frame event is sent for every logical event group, even if the group only contains a
single wp_tablet_pad_ring event. Specifically, a client may get a sequence: angle, frame, angle, frame,
etc.

Retrieve the interface name (class) of a resource object.
Returns
Interface name of the resource object.

Get the associated client
Returns
the client that owns the resource.

Returns
the internal ID of the resource

std::function<void(std::string,uint32_t)>&zwp_tablet_pad_ring_v2_t::on_set_feedback()
set compositor feedback
Parametersdescription ring description
serial serial of the mode switch event
Request that the compositor use the provided feedback string associated with this ring. This request
should be issued immediately after a wp_tablet_pad_group.mode_switch event from the corresponding group
is received, or whenever the ring is mapped to a different action. See wp_tablet_pad_group.mode_switch
for more details.
Clients are encouraged to provide context-aware descriptions for the actions associated with the ring;
compositors may use this information to offer visual feedback about the button layout (eg. on-screen
displays).
The provided string 'description' is a UTF-8 encoded string to be associated with this ring, and is
considered user-visible; general internationalization rules apply.
The serial argument will be that of the last wp_tablet_pad_group.mode_switch event received for the group
of this ring. Requests providing other serials than the most recent one will be ignored.

voidwayland::server::resource_t::post_no_memory()const[inherited]
Post 'not enough memory' error to the client
If the compositor has not enough memory to fulfill a certail request of the client, this function can be
called to notify the client of this circumstance.
boolwayland::server::resource_t::proxy_has_object()const[inherited]
Check whether this wrapper actually wraps an object.
Returns
true if there is an underlying object, false if this wrapper is empty
voidzwp_tablet_pad_ring_v2_t::source(zwp_tablet_pad_ring_v2_sourceconst&source,boolpost=true)
ring event source
Parameterssource the event source
Source information for ring events.
This event does not occur on its own. It is sent before a wp_tablet_pad_ring.frame event and carries the
source information for all events within that frame.
The source specifies how this event was generated. If the source is wp_tablet_pad_ring.source.finger, a
wp_tablet_pad_ring.stop event will be sent when the user lifts the finger off the device.
This event is optional. If the source is unknown for an interaction, no event is sent.

voidzwp_tablet_pad_ring_v2_t::stop(boolpost=true)
interaction stopped Stop notification for ring events.
For some wp_tablet_pad_ring.source types, a wp_tablet_pad_ring.stop event is sent to notify a client that
the interaction with the ring has terminated. This enables the client to implement kinetic scrolling. See
the wp_tablet_pad_ring.source documentation for information on when this event may be generated.
Any wp_tablet_pad_ring.angle events with the same source after this event should be considered as the
start of a new interaction.
