Detailed Description
touchpad gestures
A global interface to provide semantic touchpad gestures for a given pointer.
Three gestures are currently supported: swipe, pinch, and hold. Pinch and swipe gestures
follow a three-stage cycle: begin, update, end, hold gestures follow a two-stage cycle:
begin and end. All gestures are identified by a unique id.
Warning! The protocol described in this file is experimental and backward incompatible
changes may be made. Backward compatible changes may be added together with the
corresponding interface version bump. Backward incompatible changes are done by bumping
the version number in the protocol and interface names and resetting the interface
version. Once the protocol is to be declared stable, the 'z' prefix and the version number
in the protocol and interface names are removed and the interface version number is reset.

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
bool zwp_pointer_gestures_v1_t::can_get_hold_gesture () const
Check whether the get_hold_gesture function is available with the currently bound version
of the protocol.
Definition at line 6026 of file wayland-client-protocol-unstable.cpp.
bool zwp_pointer_gestures_v1_t::can_release () const
Check whether the release function is available with the currently bound version of the
protocol.
Definition at line 6014 of file wayland-client-protocol-unstable.cpp.
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
zwp_pointer_gesture_hold_v1_t zwp_pointer_gestures_v1_t::get_hold_gesture (pointer_t const &
pointer)
get hold gesture
Parameters
pointer
Create a hold gesture object. See the wl_pointer_gesture_hold interface for details.
Definition at line 6020 of file wayland-client-protocol-unstable.cpp.
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
zwp_pointer_gesture_pinch_v1_t zwp_pointer_gestures_v1_t::get_pinch_gesture (pointer_t const &
pointer)
get pinch gesture
Parameters
pointer
Create a pinch gesture object. See the wl_pointer_gesture_pinch interface for details.
Definition at line 6002 of file wayland-client-protocol-unstable.cpp.
zwp_pointer_gesture_swipe_v1_t zwp_pointer_gestures_v1_t::get_swipe_gesture (pointer_t const &
pointer)
get swipe gesture
Parameters
pointer
Create a swipe gesture object. See the wl_pointer_gesture_swipe interface for details.
Definition at line 5995 of file wayland-client-protocol-unstable.cpp.
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.
Definition at line 301 of file wayland-client.hpp.
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_pointer_gestures_v1_t::release ()
destroy the pointer gesture object Destroy the pointer gesture object. Swipe, pinch and
hold objects created via this gesture object remain valid.
Definition at line 6009 of file wayland-client-protocol-unstable.cpp.
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().
