Detailed Description

an imported surface handle

A xdg_imported object represents an imported reference to surface exported by some client. A client can use this interface to manipulate relationships between its own surfaces and the imported surface.

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

◆ 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.

◆ on_destroyed()

std::function< void()> & zxdg_imported_v2_t::on_destroyed ( )

the imported surface handle has been destroyed

The imported surface handle has been destroyed and any relationship set up has been invalidated. This may happen for various reasons, for example if the exported surface or the exported surface handle has been destroyed, if the handle used for importing was invalid.

Definition at line 8681 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.

◆ 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_parent_of()

void zxdg_imported_v2_t::set_parent_of ( surface_t surface )

set as the parent of some surface

Parameters

surface the child surface

Set the imported surface as the parent of some surface of the client. The passed surface must be a xdg_toplevel equivalent. Calling this function sets up a surface to surface relation with the same stacking and positioning semantics as xdg_toplevel.set_parent.

Definition at line 8676 of file wayland-client-protocol-unstable.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.
