- <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.
