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

◆ wrapper_type

enum wayland::proxy_t::wrapper_type
stronginherited

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

◆ c_ptr()

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

◆ create_positioner()

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 8911 of file wayland-client-protocol-unstable.cpp.

◆ get_class()

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

◆ get_id()

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
Examples
dump.cpp.

◆ get_version()

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

◆ get_wrapper_type()

wrapper_type wayland::proxy_t::get_wrapper_type ( ) const
inlineinherited

Get the type of a proxy object.

Definition at line 288 of file wayland-client.hpp.

◆ get_xdg_surface()

zxdg_surface_v6_t zxdg_shell_v6_t::get_xdg_surface ( surface_t  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.

Definition at line 8917 of file wayland-client-protocol-unstable.cpp.

◆ on_ping()

std::function< void(uint32_t)> & zxdg_shell_v6_t::on_ping ( )

check if the client is alive

Parameters
serialpass 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 8928 of file wayland-client-protocol-unstable.cpp.

◆ operator bool()

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

◆ operator!=()

bool wayland::proxy_t::operator!= ( const proxy_t right) const
inherited

Check whether two wrappers refer to different objects.

◆ operator==()

bool wayland::proxy_t::operator== ( const proxy_t right) const
inherited

Check whether two wrappers refer to the same object.

◆ pong()

void zxdg_shell_v6_t::pong ( uint32_t  serial)

respond to a ping event

Parameters
serialserial 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 8923 of file wayland-client-protocol-unstable.cpp.

◆ proxy_has_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

◆ proxy_release()

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.

◆ set_queue()

void wayland::proxy_t::set_queue ( event_queue_t  queue)
inherited

Assign a proxy to an event queue.

Parameters
queueThe 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.
