It provides enter/leave events to follow the + text input focus for a seat. + + Requests are used to enable/disable the text-input object and set + state information like surrounding and selected text or the content type. + The information about the 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 valid UTF-8 encoded, indices and lengths are in bytes. Indices + have to always point to the first byte of an UTF-8 encoded code point. + Lengths are not allowed to contain just a part of an UTF-8 encoded code + point. + + State is sent by the state requests (set_surrounding_text, + set_content_type, set_cursor_rectangle and set_preferred_language) and + an update_state request. After an enter or an input_method_change event + all state information is invalidated and needs to be resent from the + client.
