<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,

all pending state, replacing the current state. After commit, the new
