<protocol name="text">
<interface name="text_model" version="1">
<description summary="text model">
A model for text input. Adds support for text input and input methods to
applications. A text_model object is created from a text_model_factory and
corresponds typically to a text entry in an application. Requests are used
to activate/deactivate the model and set information like surrounding and
selected text or the content type. The information about entered text is
sent to the model via the pre-edit and commit events. Using this interface
removes the need for applications to directly process hardware key events
and compose text out of them.
</description>
<request name="set_surrounding_text">
<description summary="sets the surrounding text">
Sets the plain surrounding text around the input position. Cursor is the
position within the surrounding text. Anchor is the position of the
selection anchor within the surrounding text. If there is no selected
text anchor is the same as cursor.

<request name="activate">
<description summary="request activation">
Requests the model to be activated (typically when the text entry gets
focus). The seat argument is a wl_seat which maintains the focus for
this activation. The surface argument is a wl_surface assigned to the
model and tracked for focus lost. The activated event is emitted on
successful activation.

Corresponds to a text model on input method side. An input method context

Input method contexts do not keep state after deactivation and should be
destroyed after deactivation is handled.
