💖 NAME 💖

so this is wayland::zwp_p...on_source_v1_t(3), bestie — yes the title is literally truncated like that, it’s iconic — from the Wayland++ manual. it’s the whole “offer to replace the contents of the primary selection” situation. ✨

🎀 SYNOPSIS 🎀

#include <wayland-client-protocol-unstable.hpp>

Inherits wayland::proxy_t.

🌸 Detailed Description 🌸

offer to replace the contents of the primary selection 💅

The source side of a wp_primary_selection_offer, it provides a way to describe the offered data and respond to requests to transfer the requested contents of the primary selection clipboard. no cap, that’s the whole vibe.

💜 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. this is the lore, bestie. 🦋

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 🔥

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.

void zwp_primary_selection_source_v1_t::offer (std::string const & mime_type)

add an offered mime type ✨

Parameters: mime_type

This request adds a mime type to the set of mime types advertised to targets. Can be called several times to offer multiple types. periodt.

Definition at line 6558 of file wayland-client-protocol-unstable.cpp.

std::function< void()> & zwp_primary_selection_source_v1_t::on_cancelled ()

request for primary selection contents was canceled. This primary selection source is no longer valid. The client should clean up and destroy this primary selection source. 🫶

Definition at line 6569 of file wayland-client-protocol-unstable.cpp.

std::function< void(std::string, int)> & zwp_primary_selection_source_v1_t::on_send ()

send the primary selection contents 💌

Parameters: mime_type, fd

Request for the current primary selection contents from the client. Send the specified mime type over the passed file descriptor, then close it.

Definition at line 6564 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.
