Detailed Description
receive relative pointer motion events
The wp_locked_pointer interface represents a locked pointer state.
While the lock of this object is active, the wl_pointer objects of the associated seat
will not emit any wl_pointer.motion events.
This object will send the event 'locked' when the lock is activated. Whenever the lock is
activated, it is guaranteed that the locked surface will already have received pointer
focus and that the pointer will be within the region passed to the request creating this
object.
To unlock the pointer, send the destroy request. This will also destroy the
wp_locked_pointer object.
If the compositor decides to unlock the pointer the unlocked event is sent. See
wp_locked_pointer.unlock for details.
When unlocking, the compositor may warp the cursor position to the set cursor position
hint. If it does, it will not result in any relative motion events emitted via
wp_relative_pointer.
If the surface the lock was requested on is destroyed and the lock is not yet activated,
the wp_locked_pointer object is now defunct and must be destroyed.

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()> & zwp_locked_pointer_v1_t::on_locked ()
lock activation event Notification that the pointer lock of the seat's pointer is
activated.
Definition at line 5839 of file wayland-client-protocol-unstable.cpp.
std::function< void()> & zwp_locked_pointer_v1_t::on_unlocked ()
lock deactivation event Notification that the pointer lock of the seat's pointer is no
longer active. If this is a oneshot pointer lock (see wp_pointer_constraints.lifetime)
this object is now defunct and should be destroyed. If this is a persistent pointer lock
(see wp_pointer_constraints.lifetime) this pointer lock may again reactivate in the
future.
Definition at line 5844 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_locked_pointer_v1_t::set_cursor_position_hint (double surface_x, double surface_y)
set the pointer cursor position hint
Parameters
surface_x surface-local x coordinate
surface_y surface-local y coordinate
Set the cursor position hint relative to the top left corner of the surface.
If the client is drawing its own cursor, it should update the position hint to the
position of its own cursor. A compositor may use this information to warp the pointer upon
unlock in order to avoid pointer jumps.
The cursor position hint is double buffered. The new hint will only take effect when the
associated surface gets it pending state applied. See wl_surface.commit for details.
Definition at line 5827 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().
void zwp_locked_pointer_v1_t::set_region (region_t const & region)
set a new lock region
Parameters
region region of surface
Set a new region used to lock the pointer.
The new lock region is double-buffered. The new lock region will only take effect when the
associated surface gets its pending state applied. See wl_surface.commit for details.
For details about the lock region, see wp_locked_pointer.
