# Clutter Text

#### Description [src]

    class Clutter.Text : Clutter.Actor
      implements Atk.ImplementorIface, Clutter.Animatable {

An actor for displaying and editing text

`ClutterText` is an actor that displays custom text using Pango as the text rendering engine.

`ClutterText` also allows inline editing of the text if the actor is set editable using `clutter_text_set_editable()`.

Selection using keyboard or pointers can be enabled using `clutter_text_set_selectable()`.
