40  * #GtkSearchEntry is a subclass of #GtkEntry that has been
41  * tailored for use as a search entry.
42  * 
43  * It will show an inactive symbolic “find” icon when the search
44  * entry is empty, and a symbolic “clear” icon when there is text.
45  * Clicking on the “clear” icon will empty the search entry.
46  * 
47  * Note that the search/clear icon is shown using a secondary
48  * icon, and thus does not work if you are using the secondary
49  * icon position for some other purpose.
50  * 
51  * To make filtering appear more reactive, it is a good idea to
52  * not react to every change in the entry text immediately, but
53  * only after a short delay. To support this, #GtkSearchEntry
54  * emits the #GtkSearchEntry::search-changed signal which can
55  * be used instead of the #GtkEditable::changed signal.
56  * 
57  * The #GtkSearchEntry::previous-match, #GtkSearchEntry::next-match
58  * and #GtkSearchEntry::stop-search signals can be used to implement
59  * moving between search results and ending the search.
60  * 
61  * Often, GtkSearchEntry will be fed events by means of being
62  * placed inside a #GtkSearchBar. If that is not the case,
63  * you can use gtk_search_entry_handle_event() to pass events.
