Detailed Description

interface for exporting surfaces

A global interface used for exporting surfaces that can later be imported using xdg_importer.

Definition at line 6638 of file wayland-client-protocol-unstable.hpp.

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

◆ export_toplevel()

zxdg_exported_v2_t zxdg_exporter_v2_t::export_toplevel ( surface_t surface )

export a toplevel surface

Returns: the new xdg_exported object

Parameters

surface the surface to export

The export_toplevel request exports the passed surface so that it can later be imported via xdg_importer. When called, a new xdg_exported object will be created and xdg_exported.handle will be sent immediately. See the corresponding interface and event for details.

A surface may be exported multiple times, and each exported handle may be used to create a xdg_imported multiple times. Only xdg_toplevel equivalent surfaces may be exported.

Definition at line 8484 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.

◆ 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.

◆ 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

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.
