38 /**
39  * #GtkSearchEntry is a subclass of #GtkEntry that has been
40  * tailored for use as a search entry.
41  * 
42  * It will show an inactive symbolic “find” icon when the search
43  * entry is empty, and a symbolic “clear” icon when there is text.
44  * Clicking on the “clear” icon will empty the search entry.
45  * 
46  * Note that the search/clear icon is shown using a secondary
47  * icon, and thus does not work if you are using the secondary
48  * icon position for some other purpose.
49  * 
50  * To make filtering appear more reactive, it is a good idea to
51  * not react to every change in the entry text immediately, but
52  * only after a short delay. To support this, #GtkSearchEntry
53  * emits the #GtkSearchEntry::search-changed signal which can
54  * be used instead of the #GtkEditable::changed signal.
55  * 
56  * The #GtkSearchEntry::previous-match, #GtkSearchEntry::next-match
57  * and #GtkSearchEntry::stop-search signals can be uesd to implement
58  * moving between search results and ending the search.
59  * 
60  * Often, GtkSearchEntry will be fed events by means of being
61  * placed inside a #GtkSearchEntry. If that is not the case,
62  * you can use gtk_search_entry_handle_event() to pass events.
