Detailed Description

text input

An object used for text input. Adds support for text input and input methods to applications. A text_input object is created from a wl_text_input_manager and corresponds typically to a text entry in an application.

Requests are used to activate/deactivate the text_input object and set state information like surrounding and selected text or the content type. The information about entered text is sent to the text_input object via the pre-edit and commit events. Using this interface removes the need for applications to directly process hardware key events and compose text out of them.

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 The text input can then ignore events from the input method which are based on an outdated state (for example after a reset).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

◆ activate()

void zwp_text_input_v1_t::activate	(	seat_t	seat,
		surface_t	surface
	)

request activation

Parameters

seat
surface

Requests the text_input object to be activated (typically when the text entry gets focus).

The seat argument is a wl_seat which maintains the focus for this activation. The surface argument is a wl_surface assigned to the text_input object and tracked for focus lost. The enter event is emitted on successful activation.

Definition at line 7575 of file wayland-client-protocol-unstable.cpp.

◆ 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

void zwp_text_input_v1_t::commit_state ( uint32_t serial )

Parameters

serial used to identify the known state

Definition at line 7620 of file wayland-client-protocol-unstable.cpp.

◆ deactivate()

void zwp_text_input_v1_t::deactivate ( seat_t seat )

request deactivation

Parameters

seat

Requests the text_input object to be deactivated (typically when the text entry lost focus). The seat argument is a wl_seat which was used for activation.

Definition at line 7580 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.

◆ 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

commit

Parameters

serial	serial of the latest known text input state
text

Notify when text should be inserted into the editor widget. 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 also be 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 should be removed.

Definition at line 7665 of file wayland-client-protocol-unstable.cpp.

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 a wl_keyboard key_state. Modifiers are a mask for effective modifiers (where the modifier indices are set by the modifiers_map event)

This event is handled as part of a following preedit_string event.

Definition at line 7655 of file wayland-client-protocol-unstable.cpp.

◆ on_text_direction()

std::function< void(uint32_t, zwp_text_input_v1_text_direction)> & zwp_text_input_v1_t::on_text_direction ( )

text direction

Parameters

serial	serial of the latest known text input state

Examples: foreign_display.cpp.

◆ reset()

void zwp_text_input_v1_t::reset ( )

reset

Should be called by an editor widget when the input state should be reset, for example after the text was changed outside of the normal input method flow.

Definition at line 7595 of file wayland-client-protocol-unstable.cpp.

◆ set_content_type()

void zwp_text_input_v1_t::set_content_type	(	zwp_text_input_v1_content_hint	hint,
		zwp_text_input_v1_content_purpose	purpose
	)

set content purpose and hint

Parameters

hint
purpose

Sets the content purpose and content hint. While the purpose is the basic purpose of an input field, the hint flags allow to modify some of the behavior.

When no content type is explicitly set, a normal content purpose with default hints (auto completion, auto correction, auto capitalization) should be assumed.

Definition at line 7605 of file wayland-client-protocol-unstable.cpp.

◆ set_cursor_rectangle()

void zwp_text_input_v1_t::set_cursor_rectangle	(	int32_t	x,

Sets a specific language. This allows for example a virtual keyboard to show a language specific layout. The "language" argument is an RFC-3066 format language tag.

It could be used for example in a word processor to indicate the language of the currently edited document or in an instant message application which tracks languages of contacts.

Definition at line 7615 of file wayland-client-protocol-unstable.cpp.

◆ set_queue()

void wayland::proxy_t::set_queue ( event_queue_t queue )

inherited

◆ set_surrounding_text()

void zwp_text_input_v1_t::set_surrounding_text	(	std::string	text,
		uint32_t	cursor,
		uint32_t	anchor
	)

Parameters

text
cursor
anchor

Sets the plain surrounding text around the input position. Text is UTF-8 encoded. Cursor is the byte offset within the surrounding text. Anchor is the byte offset of the selection anchor within the surrounding text. If there is no selected text anchor, then it is the same as cursor.
