Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Destroy

This is a destructor, once received this object cannot be used any longer.

CommitString

commit string

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.

Fields

serial: u32

serial of the latest known text input state

text: String

PreeditString

pre-edit string

Send the pre-edit string text to the application text input.

The commit text can be used to replace the pre-edit text on reset (for example on unfocus).

Previously sent preedit_style and preedit_cursor requests are also processed by the text_input.

Fields

serial: u32

serial of the latest known text input state

text: String

commit: String

PreeditStyling

pre-edit styling

Set the styling information on composing text. The style is applied for length in bytes from index relative to the beginning of the composing text (as byte offset). Multiple styles can be applied to a composing text.

This request should be sent before sending a preedit_string request.

Fields

index: u32

length: u32

style: u32

PreeditCursor

pre-edit cursor

Set the cursor position inside the composing text (as byte offset) relative to the start of the composing text.

When index is negative no cursor should be displayed.

This request should be sent before sending a preedit_string request.

Fields

index: i32

DeleteSurroundingText

delete text

Remove the surrounding text.

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

Fields

index: i32

length: u32

CursorPosition

set cursor to a new position

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.

Fields

index: i32

anchor: i32

ModifiersMap

Fields

map: Vec<u8>

Keysym

keysym

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.

Fields

serial: u32

serial of the latest known text input state

time: u32

sym: u32

state: u32

modifiers: u32

GrabKeyboard

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.

Fields

keyboard: New<WlKeyboard>

Key

forward key event

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.

Fields

serial: u32

serial from wl_keyboard::key

time: u32

time from wl_keyboard::key

key: u32

key from wl_keyboard::key

state: u32

state from wl_keyboard::key

Modifiers

forward modifiers event

Forward a wl_keyboard::modifiers 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::modifiers event.

Fields

serial: u32

serial from wl_keyboard::modifiers

mods_depressed: u32

mods_depressed from wl_keyboard::modifiers

mods_latched: u32

mods_latched from wl_keyboard::modifiers

mods_locked: u32

mods_locked from wl_keyboard::modifiers

group: u32

group from wl_keyboard::modifiers

Language

Fields

serial: u32

serial of the latest known text input state

language: String

TextDirection

Fields

serial: u32

serial of the latest known text input state

direction: u32
