/**
 * SECTION:gtksearchentry
 * @Short_description: An entry which shows a search icon
 * @Title: GtkSearchEntry
 *
 * #GtkSearchEntry is an entry widget that has been tailored for use
 * as a search entry. The main aPI for interacting with a GtkSearchEntry
 * as entry is the #GtkEditable interface.
 *
 * It will show an inactive symbolic “find” icon when the search
 * entry is empty, and a symbolic “clear” icon when there is text.
 * Clicking on the “clear” icon will empty the search entry.
 *
 * To make filtering appear more reactive, it is a good idea to
 * not react to every change in the entry text immediately, but
 * only after a short delay. To support this, #GtkSearchEntry
 * emits the #GtkSearchEntry::search-changed signal which can
 * be used instead of the #GtkEditable::changed signal.
 *
 * The #GtkSearchEntry::previous-match, #GtkSearchEntry::next-match
 * and #GtkSearchEntry::stop-search signals can be used to implement
 * moving between search results and ending the search.
 *
 * Often, GtkSearchEntry will be fed events by means of being
 * placed inside a #GtkSearchBar. If that is not the case,
 * you can use gtk_search_entry_set_key_capture_widget() to let it
 * capture key input from another widget.
 *
 * # CSS Nodes
 *
 * |[<!-- language="plain" -->
 * entry.search
 * ╰── text
 * ]|
 *
 * GtkSearchEntry has a single CSS node with name entry that carries
 * a .sarch style class, and the text node is a child of that.
 *
 * # Accessibility
 *
 * GtkSearchEntry uses the #GTK_ACCESSIBLE_ROLE_SEARCH_BOX role.
