31 An object used for text input. Adds support for text input and input
32 methods to applications. A text-input object is created from a
33 wl_text_input_manager and corresponds typically to a text entry in an
35 Requests are used to activate/deactivate the text-input object and set
36 state information like surrounding and selected text or the content type.
37 The information about entered text is sent to the text-input object via
38 the pre-edit and commit events. Using this interface removes the need
39 for applications to directly process hardware key events and compose text
42 Text is generally UTF-8 encoded, indices and lengths are in bytes.
44 Serials are used to synchronize the state between the text input and
45 an input method. New serials are sent by the text input in the
46 commit_state request and are used by the input method to indicate
47 the known text input state in events like preedit_string, commit_string,
48 and keysym. The text input can then ignore events from the input method
49 which are based on an outdated state (for example after a reset).

53 Requests the text-input object to be activated (typically when the

55 The seat argument is a wl_seat which maintains the focus for this

57 text-input object and tracked for focus lost. The enter event
58 is emitted on successful activation.
