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_string 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. + + Focus moving throughout surfaces will result in the emission of + gtk_text_input.enter and gtk_text_input.leave events. The focused + surface must perform gtk_text_input.enable and + gtk_text_input.disable requests as the keyboard focus moves across + editable and non-editable elements of the UI. Those two requests are not + expected to be paired with each other, the compositor must be able to + handle consecutive series of the same request. + + State is sent by the state requests (set_surrounding_text, + set_content_type and set_cursor_rectangle) and a commit request. + After an enter event or disable request all state information is + invalidated and needs to be resent by the client. + + This protocol defines requests and events necessary for regular clients + to communicate with an input method. The gtk_input_method protocol + defines the interfaces necessary to implement standalone input methods. + If a compositor implements both interfaces, it will be the arbiter of the + communication between both. + + 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. + </description> + + <request name="destroy" type="destructor"> + <description summary="Destroy the wp_text_input"> + Destroy the wp_text_input object.
