<interface name="gtk_text_input" version="1">
<description summary="text input">
The gtk_text_input interface represents text input and input methods
associated with a seat. 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.

Make sure to always send some text before and after the cursor
except when the cursor is at the beginning or end of text.
When there was a configure_surrounding_text event take the
before_cursor and after_cursor arguments into account for picking how
much surrounding text to send.
There is a maximum length of wayland messages so text can not be
longer than 4000 bytes.
