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 class 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.
Definition at line 7821 of file wayland-client-protocol-unstable.cpp.
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.
Examples
foreign_display.cpp.
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().
Examples
proxy_wrapper.cpp.
