Detailed Description
create desktop-style surfaces
xdg_shell allows clients to turn a wl_surface into a 'real window' which can be dragged,
resized, stacked, and moved around by the user. Everything about this interface is suited
towards traditional desktop environments.

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
zxdg_positioner_v6_t zxdg_shell_v6_t::create_positioner ()
create a positioner object Create a positioner object. A positioner object is used to
position surfaces relative to some parent surface. See the interface description and
xdg_surface.get_popup for details.
Definition at line 9679 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
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.
Definition at line 301 of file wayland-client.hpp.
zxdg_surface_v6_t zxdg_shell_v6_t::get_xdg_surface (surface_t const & surface)
create a shell surface from a surface
Parameters
surface
This creates an xdg_surface for the given surface. While xdg_surface itself is not a role,
the corresponding surface may only be assigned a role extending xdg_surface, such as
xdg_toplevel or xdg_popup.
This creates an xdg_surface for the given surface. An xdg_surface is used as basis to
define a role to a given surface, such as xdg_toplevel or xdg_popup. It also manages
functionality shared between xdg_surface based surface roles.
See the documentation of xdg_surface for more details about what an xdg_surface is and how
it is used.

std::function< void(uint32_t)> & zxdg_shell_v6_t::on_ping ()
check if the client is alive
Parameters
serial pass this to the pong request
The ping event asks the client if it's still alive. Pass the serial specified in the event
back to the compositor by sending a 'pong' request back with the specified serial. See
xdg_shell.ping.
Compositors can use this to determine if the client is still alive. It's unspecified what
will happen if the client doesn't respond to the ping request, or in what timeframe.
Clients should try to respond in a reasonable amount of time.
A compositor is free to ping in any way it wants, but a client must always respond to any
xdg_shell object it created.
Definition at line 9699 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.
void zxdg_shell_v6_t::pong (uint32_t serial)
respond to a ping event
Parameters
serial serial of the ping event
A client must respond to a ping event with a pong request or the client may be deemed
unresponsive. See xdg_shell.ping.
Definition at line 9693 of file wayland-client-protocol-unstable.cpp.
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 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().
