input_method_unstable_v1

# zwp_input_method_context_v1

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 The text input can then ignore events from the input method which are based on an outdated state (for example after a reset).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

Requests
- #
  destroy
  
  void zwp_input_method_context_v1_destroy(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1
  )
- #
  commit_string
  
  commit string
  
  void zwp_input_method_context_v1_commit_string(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  uint32_t serial, /* serial of the latest known text input state */
  
  const char* 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.
- #
  preedit_string
  
  pre-edit string
  
  void zwp_input_method_context_v1_preedit_string(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  uint32_t serial, /* serial of the latest known text input state */
  
  const char* text,
  
  const char* commit
  )
  
  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.
- #
  preedit_styling
  
  pre-edit styling
  
  void zwp_input_method_context_v1_preedit_styling(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  uint32_t index,
  
  uint32_t length,
  
  uint32_t style
  )
  
  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.
- #
  preedit_cursor
  
  pre-edit cursor
  
  void zwp_input_method_context_v1_preedit_cursor(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  int32_t index
  )
  
  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.
- #
  delete_surrounding_text
  
  delete text
  
  void zwp_input_method_context_v1_delete_surrounding_text(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  int32_t index,
  
  uint32_t length
  )
  
  Remove the surrounding text. This request will be handled on the text_input side directly following a commit_string request.
- #
  cursor_position
  
  set cursor to a new position
  
  void zwp_input_method_context_v1_cursor_position(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  int32_t index,
  
  int32_t 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.

  uint32_t time,
  
  uint32_t sym,
  
  uint32_t state,
  
  uint32_t 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.
- #
  grab_keyboard
  
  grab hardware keyboard
  
  struct wl_keyboard* zwp_input_method_context_v1_grab_keyboard(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1
  )
  
  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.
- #
  key
  
  forward key event
  
  void zwp_input_method_context_v1_key(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,
  
  uint32_t serial, /* serial from wl_keyboard::key */
  
  uint32_t time, /* time from wl_keyboard::key */
  
  uint32_t key, /* key from wl_keyboard::key */
  
  uint32_t 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.
- #
  modifiers
  
  forward modifiers event
  
  void zwp_input_method_context_v1_modifiers(
  struct zwp_input_method_context_v1* zwp_input_method_context_v1,

  uint32_t mods_depressed, /* mods_depressed from wl_keyboard::modifiers */
  
  uint32_t mods_latched, /* mods_latched from wl_keyboard::modifiers */
  
  uint32_t mods_locked, /* mods_locked from wl_keyboard::modifiers */
  
  uint32_t group /* group from wl_keyboard::modifiers */
  )
  
  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.

  surrounding text event
  
  const char* text
  
  uint32_t cursor
  
  uint32_t anchor
  
  The plain surrounding text around the input position. Cursor is the position in bytes within the surrounding text relative to the beginning of the text. Anchor is the position in bytes of the selection anchor within the surrounding text relative to the beginning of the text. If there is no selected text then anchor is the same as cursor.

# zwp_input_method_v1

An input method object is responsible for composing text in response to input from hardware or virtual keyboards. There is one input method object per seat. On activate there is a new input method context object created which allows the input method to communicate with the text input.

Events
- #
  activate
  
  activate event
  
  struct zwp_input_method_context_v1* id
  
  A text input was activated. Creates an input method context object which allows communication with the text input.
- #
  deactivate
  
  deactivate event
  
  struct zwp_input_method_context_v1* context
  
  The text input corresponding to the context argument was deactivated. The input method context should be destroyed after deactivation is handled.
