/**
 * SECTION:st-entry
 * @short_description: Widget for displaying text
 *
 * #StEntry is a simple widget for displaying text. It derives from
 * #StWidget to add extra style and placement functionality over
 * #ClutterText. The internal #ClutterText is publicly accessibly to allow
 * applications to set further properties.
 *
 * #StEntry supports the following pseudo style states:
 * <itemizedlist>
 *  <listitem>
 *   <para>focus: the widget has focus</para>
 *  </listitem>
 *  <listitem>
 *   <para>indeterminate: the widget is showing the hint text</para>
 *  </listitem>
 * </itemizedlist>
