Detailed Description
an exported surface handle
An xdg_exported object represents an exported reference to a surface. The exported surface may be referenced as long as the xdg_exported object not destroyed. Destroying the xdg_exported invalidates any relationship the importer may have established using xdg_imported.

Member Enumeration Documentation
enum class 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_tis destructed. User data is set.
- display
-
C pointer is a wl_display*. No events are dispatched, wl_display_disconnect is called when the
proxy_tis 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_tis destructed, user data is not touched. Consequently, there is no reference counting for theproxy_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_tis destroyed. Reference counting is active. A reference to theproxy_tcreating 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
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.

std::function< void(std::string)> & zxdg_exported_v2_t::on_handle ()
the exported surface handle
Parameters
handle the exported surface handle
The handle event contains the unique handle of this exported surface reference. It may be shared with any client, which then can use it to import the surface by calling xdg_importer.import_toplevel. A handle may be used to import the surface multiple times.
Definition at line 9373 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.
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.
Examples foreign_display.cpp.
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().
Examples proxy_wrapper.cpp.
