Detailed Description

input method context

Corresponds to a text input on the input method side. An input method context is created on text input activation on the input method side. It allows receiving information about the text input from the application via events. Input method contexts do not keep state after deactivation and should be destroyed after deactivation is handled.

Text is generally UTF-8 encoded, indices and lengths are in bytes.

Serials are used to synchronize the state between the text input and an input method. New serials are sent by the text input in the commit_state request and are used by the input method to indicate the known text input state in events like preedit_string, commit_string, and keysym. The text input can then ignore events from the input method which are based on an outdated state (for example after a reset).

Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the 'z' prefix and the version number in the protocol and interface names are removed and the interface version number is reset.

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

◆ commit_string()

void zwp_input_method_context_v1_t::commit_string	(	uint32_t	serial,
		std::string	text
	)

commit string

Parameters

serial	serial of the latest known text input state
text

Send the commit string text for insertion to the application.

The text to commit could be either just a single character after a key press or the result of some composing (pre-edit). It could be also an empty text when some text should be removed (see delete_surrounding_text) or when the input cursor should be moved (see cursor_position).

Any previously set composing text will be removed.

Definition at line 4265 of file wayland-client-protocol-unstable.cpp.

◆ cursor_position()

void zwp_input_method_context_v1_t::cursor_position	(	int32_t	index,
		int32_t	anchor
	)

set cursor to a new position

Parameters

index
anchor

Set the cursor and anchor to a new position. Index is the new cursor position in bytes (when >= 0 this is relative to the end of the inserted text, otherwise it is relative to the beginning of the inserted text). Anchor is the new anchor position in bytes (when >= 0 this is relative to the end of the inserted text, otherwise it is relative to the beginning of the inserted text). When there should be no selected text, anchor should be the same as index.

This request will be handled on the text_input side directly following a commit_string request.

Definition at line 4290 of file wayland-client-protocol-unstable.cpp.

◆ delete_surrounding_text()

void zwp_input_method_context_v1_t::delete_surrounding_text	(	int32_t	index,
		uint32_t	length
	)

delete text

Parameters

index
length

Remove the surrounding text.

This request will be handled on the text_input side directly following a commit_string request.

Definition at line 4285 of file wayland-client-protocol-unstable.cpp.

◆ 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.

◆ grab_keyboard()

keyboard_t zwp_input_method_context_v1_t::grab_keyboard ( )

grab hardware keyboard

Allow an input method to receive hardware keyboard input and process key events to generate text events (with pre-edit) over the wire. This allows input methods which compose multiple key events for inputting text like it is done for CJK languages.

Definition at line 4305 of file wayland-client-protocol-unstable.cpp.

◆ key()

void zwp_input_method_context_v1_t::key	(	uint32_t	serial,
		uint32_t	time,
		uint32_t	key,

	)

forward key event

Parameters

serial	serial from wl_keyboard::key
time	time from wl_keyboard::key
key	key from wl_keyboard::key
state	state from wl_keyboard::key

Forward a wl_keyboard::key event to the client that was not processed by the input method itself. Should be used when filtering key events with grab_keyboard. The arguments should be the ones from the wl_keyboard::key event.

For generating custom key events use the keysym request instead.

Definition at line 4311 of file wayland-client-protocol-unstable.cpp.

◆ keysym()

void zwp_input_method_context_v1_t::keysym	(	uint32_t	serial,

		uint32_t	modifiers
	)

keysym

Parameters

serial	serial of the latest known text input state
time
sym
state
modifiers

Notify when a key event was sent. Key events should not be used for normal text input operations, which should be done with commit_string, delete_surrounding_text, etc. The key event follows the wl_keyboard key event convention. Sym is an XKB keysym, state is a wl_keyboard key_state.
