Detailed Description
pad strip
A linear interaction area, such as the strips found in Wacom Cintiq models.
Events on a strip are logically grouped by the wl_tablet_pad_strip.frame event.

Member Enumeration Documentation
enum wayland::proxy_t::wrapper_type [strong], [inherited]
Underlying wl_proxy type and properties of a proxy_t that affect construction,
destruction, and event handling
Enumerator
standard
C pointer is a standard type compatible with wl_proxy*. Events are dispatched and
it is destructed when the proxy_t is destructed. User data is set.
display
C pointer is a wl_display*. No events are dispatched, wl_display_disconnect is
called when the proxy_t is destructed. User data is set.
foreign
C pointer is a standard type compatible with wl_proxy*, but another library owns it
and it should not be touched in a way that could affect the operation of the other
library. No events are dispatched, wl_proxy_destroy is not called when the proxy_t
is destructed, user data is not touched. Consequently, there is no reference
counting for the proxy_t. Lifetime of such wrappers should preferably be short to
minimize the chance that the owning library decides to destroy the wl_proxy.
proxy_wrapper
C pointer is a wl_proxy* that was constructed with wl_proxy_create_wrapper. No
events are dispatched, wl_proxy_wrapper_destroy is called when the proxy_t is
destroyed. Reference counting is active. A reference to the proxy_t creating this
proxy wrapper is held to extend its lifetime until after the proxy wrapper is
destroyed.

Member Function Documentation
wl_proxy* wayland::proxy_t::c_ptr () const [inherited]
Get a pointer to the underlying C struct.
Returns
The underlying wl_proxy wrapped by this proxy_t if it exists, otherwise an exception
is thrown
std::string wayland::proxy_t::get_class () const [inherited]
Get the interface name (class) of a proxy object.
Returns
The interface name of the object associated with the proxy
uint32_t wayland::proxy_t::get_id () const [inherited]
Get the id of a proxy object.
Returns
The id the object associated with the proxy
uint32_t wayland::proxy_t::get_version () const [inherited]
Get the protocol object version of a proxy object. Gets the protocol object version of a
proxy object, or 0 if the proxy was created with unversioned API.
A returned value of 0 means that no version information is available, so the caller must
make safe assumptions about the object's real version.
display_t will always return version 0.
Returns
The protocol object version of the proxy or 0
wrapper_type wayland::proxy_t::get_wrapper_type () const [inline], [inherited]
Get the type of a proxy object.

std::function< void(uint32_t)> & zwp_tablet_pad_strip_v2_t::on_frame ()
end of a strip event sequence
Parameters
time timestamp with millisecond granularity
Indicates the end of a set of events that represent one logical hardware strip event. A
client is expected to accumulate the data in all events within the frame before
proceeding.
All wp_tablet_pad_strip events before a wp_tablet_pad_strip.frame event belong logically
together. For example, on termination of a finger interaction on a strip the compositor
will send a wp_tablet_pad_strip.source event, a wp_tablet_pad_strip.stop event and a
wp_tablet_pad_strip.frame event.
A wp_tablet_pad_strip.frame event is sent for every logical event group, even if the group
only contains a single wp_tablet_pad_strip event. Specifically, a client may get a
sequence: position, frame, position, frame, etc.

std::function< void(uint32_t)> & zwp_tablet_pad_strip_v2_t::on_position ()
position changed
Parameters
position the current position
Sent whenever the position on a strip changes.
The position is normalized to a range of [0, 65535], the 0-value represents the top-most
and/or left-most position of the strip in the pad's current rotation.
Definition at line 7811 of file wayland-client-protocol-unstable.cpp.
std::function< void(zwp_tablet_pad_strip_v2_source)> & zwp_tablet_pad_strip_v2_t::on_source ()
strip event source
Parameters
source the event source
Source information for strip events.
This event does not occur on its own. It is sent before a wp_tablet_pad_strip.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_strip.source.finger, a wp_tablet_pad_strip.stop event will be sent when the
user lifts their finger off the device.
This event is optional. If the source is unknown for an interaction, no event is sent.
Definition at line 7806 of file wayland-client-protocol-unstable.cpp.
std::function< void()> & zwp_tablet_pad_strip_v2_t::on_stop ()
interaction stopped Stop notification for strip events.
For some wp_tablet_pad_strip.source types, a wp_tablet_pad_strip.stop event is sent to
notify a client that the interaction with the strip has terminated. This enables the
client to implement kinetic scrolling. See the wp_tablet_pad_strip.source documentation
for information on when this event may be generated.
Any wp_tablet_pad_strip.position events with the same source after this event should be
considered as the start of a new interaction.
Definition at line 7816 of file wayland-client-protocol-unstable.cpp.
wayland::proxy_t::operator bool () const [inherited]
Check whether this wrapper actually wraps an object.
Returns
true if there is an underlying object, false if this wrapper is empty
bool wayland::proxy_t::operator!= (const proxy_t & right) const [inherited]
Check whether two wrappers refer to different objects.
bool wayland::proxy_t::operator== (const proxy_t & right) const [inherited]
Check whether two wrappers refer to the same object.
bool wayland::proxy_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
void wayland::proxy_t::proxy_release () [inherited]
Release the wrapped object (if any), making this an empty wrapper. Note that display_t
instances cannot be released this way. Attempts to do so are ignored.
void zwp_tablet_pad_strip_v2_t::set_feedback (std::string const & description, uint32_t
serial)
set compositor feedback
Parameters
description strip description
serial serial of the mode switch event
Requests the compositor to use the provided feedback string associated with this strip.
This request should be issued immediately after a wp_tablet_pad_group.mode_switch event
from the corresponding group is received, or whenever the strip 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 strip, and 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 strip. Requests providing other serials than the most
recent one will be ignored.

void wayland::proxy_t::set_queue (event_queue_t queue) [inherited]
Assign a proxy to an event queue.
Parameters
queue The event queue that will handle this proxy
Assign proxy to event queue. Events coming from proxy will be queued in queue instead of
the display's main queue.
See also: display_t::dispatch_queue().
