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_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.

Definition at line 116 of file wayland-client.hpp.

wl_proxy * wayland::proxy_t::c_ptr () const [inherited]¶

Get a pointer to the underlying C struct.

Returns

std::string wayland::proxy_t::get_class () const [inherited]¶

Get the interface name (class) of a proxy object.

Returns

uint32_t wayland::proxy_t::get_id () const [inherited]¶

Get the id of a proxy object.

Returns

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

wrapper_type wayland::proxy_t::get_wrapper_type () const [inline], [inherited]¶

Get the type of a proxy object.

Definition at line 302 of file wayland-client.hpp.

std::function< void()> & zwp_tablet_v2_t::on_done ()¶

tablet description events sequence complete This event is sent immediately to signal the end of the initial burst of descriptive events. A client may consider the static description of the tablet to be complete and finalize initialization of the tablet.

Definition at line 7616 of file wayland-client-protocol-unstable.cpp.

std::function< void(uint32_t, uint32_t)> & zwp_tablet_v2_t::on_id ()¶

tablet device USB vendor/product id

Parameters

This event is sent in the initial burst of events before the wp_tablet.done event.

Definition at line 7606 of file wayland-client-protocol-unstable.cpp.

std::function< void(std::string)> & zwp_tablet_v2_t::on_name ()¶

tablet device name

Parameters

This event is sent in the initial burst of events before the wp_tablet.done event.

Definition at line 7601 of file wayland-client-protocol-unstable.cpp.

std::function< void(std::string)> & zwp_tablet_v2_t::on_path ()¶

path to the device

Parameters

A system-specific device path that indicates which device is behind this wp_tablet. This information may be used to gather additional information about the device, e.g. through libwacom.

A device may have more than one device path. If so, multiple wp_tablet.path events are sent. A device may be emulated and not have a device path, and in that case this event will not be sent.

The format of the path is unspecified, it may be a device node, a sysfs path, or some other identifier. It is up to the client to identify the string provided.

This event is sent in the initial burst of events before the wp_tablet.done event.

Definition at line 7611 of file wayland-client-protocol-unstable.cpp.

std::function< void()> & zwp_tablet_v2_t::on_removed ()¶

tablet removed event Sent when the tablet has been removed from the system. When a tablet is removed, some tools may be removed.

When this event is received, the client must wp_tablet.destroy the object.

Definition at line 7621 of file wayland-client-protocol-unstable.cpp.

wayland::proxy_t::operator bool () const [inherited]¶

Check whether this wrapper actually wraps an object.

Returns

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

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

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.
