<description summary="Protocol for composing text">
|
||||
This protocol allows compositors to act as input methods and to send text
|
||||
to applications. A text input object is used to manage state of what are
|
||||
typically text entry fields in the application.
|
||||
|
||||
This document adheres to the RFC 2119 when using words like "must",
|
||||
"should", "may", etc.
|
||||
|
||||
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.

<interface name="zwp_text_input_v3" version="1">
|
||||
<description summary="text input">
|
||||
The zwp_text_input_v3 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 preedit_string and commit_string events.
|
||||
|
||||
Text is valid UTF-8 encoded, indices and lengths are in bytes. Indices
|
||||
must not point to middle bytes inside a code point: they must either
|
||||
point to the first byte of a code point or to the end of the buffer.
|
||||
Lengths must be measured between two valid indices.
|
||||
|
||||
Focus moving throughout surfaces will result in the emission of
|
||||
zwp_text_input_v3.enter and zwp_text_input_v3.leave events. The focused
|
||||
surface must commit zwp_text_input_v3.enable and
|
||||
zwp_text_input_v3.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.

Requests text input on the surface previously obtained from the enter

This request must be issued every time the active text input changes
|

to a new one, including within the current surface. Use
|
||||
zwp_text_input_v3.disable when there is no longer any input focus on
|
||||
the current surface.
|
||||
|
||||
Clients must not enable more than one text input on the single seat
|
||||
and should disable the current text input before enabling the new one.
|
||||
At most one instance of text input may be in enabled state per instance,
|
||||
Requests to enable the another text input when some text input is active
|
||||
must be ignored by compositor.
|

This request resets all state associated with previous enable, disable,
|

set_surrounding_text, set_text_change_cause, set_content_type, and
|
||||
set_cursor_rectangle requests, as well as the state associated with
|
||||
preedit_string, commit_string, and delete_surrounding_text events.
|
||||
|
||||
The set_surrounding_text, set_content_type and set_cursor_rectangle
|
||||
requests must follow if the text input supports the necessary
|
||||
functionality.
|

State set with this request is double-buffered. It will get applied on
|

the next zwp_text_input_v3.commit request, and stay valid until the

The client should notify the compositor of any changes in any of the
|
||||
values carried with this request, including changes caused by handling
|

incoming text-input events as well as changes caused by other
|

mechanisms like keyboard typing.
|

|
||||
If the client is unaware of the text around the cursor, it should not

issue this request, to signify lack of support to the compositor.
|

|

Text is UTF-8 encoded, and should include the cursor position, the

complete selection and additional characters before and after them.
|
||||
There is a maximum length of wayland messages, so text can not be
|
||||
longer than 4000 bytes.
|

|

Cursor is the byte offset of the cursor within text buffer.
|
||||
|
||||
Anchor is the byte offset of the selection anchor within text buffer.
|

If there is no selected text, anchor is the same as cursor.
|

If any preedit text is present, it is replaced with a cursor for the

purpose of this event.

The initial state for affected fields is empty, meaning that the text

Text input state (enabled status, content purpose, content hint,
