interface for importing surfaces

A global interface used for importing surfaces exported by xdg_exporter. With this interface, a client can create a reference to a surface of another client.

Underlying wl_proxy type and properties of a proxy_t that affect construction, destruction, and event handling

Enumerator

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.
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.
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.
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.

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 the interface name (class) of a proxy object.

Returns

The interface name of the object associated with the proxy

Get the id of a proxy object.

Returns

The id the object associated with the proxy

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.

zxdg_imported_v1_t zxdg_importer_v1_t::import (std::string const & handle)

import a surface

Returns

the new xdg_imported object

Parameters

handle the exported surface handle

The import request imports a surface from any client given a handle retrieved by exporting said surface using xdg_exporter.export. When called, a new xdg_imported object will be created. This new object represents the imported surface, and the importing client can manipulate its relationship using it. See xdg_imported for details.

Definition at line 9041 of file wayland-client-protocol-unstable.cpp.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

Check whether two wrappers refer to different objects.

Check whether two wrappers refer to the same object.

Check whether this wrapper actually wraps an object.

Returns

true if there is an underlying object, false if this wrapper is empty

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.

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.
