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.

zwp_xwayland_keyboard_grab_v1_t zwp_xwayland_keyboard_grab_manager_v1_t::grab_keyboard (surface_t const &
surface, seat_t const & seat)
grab the keyboard to a surface
Parameters
surface surface to report keyboard events to
seat the seat for which the keyboard should be grabbed
The grab_keyboard request asks for a grab of the keyboard, forcing the keyboard focus for the given seat
upon the given surface.
The protocol provides no guarantee that the grab is ever satisfied, and does not require the compositor
to send an error if the grab cannot ever be satisfied. It is thus possible to request a keyboard grab
that will never be effective.
The protocol:
does not guarantee that the grab itself is applied for a surface, the grab request may be silently
ignored by the compositor, does not guarantee that any events are sent to this client even if the grab is
applied to a surface, does not guarantee that events sent to this client are exhaustive, a compositor may
filter some events for its own consumption, does not guarantee that events sent to this client are
continuous, a compositor may change and reroute keyboard events while the grab is nominally active.

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 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.
