39 * SECTION:ctksearchentry
40 * @Short_description: An entry which shows a search icon
41 * @Title: CtkSearchEntry
42 *
43 * #CtkSearchEntry is a subclass of #CtkEntry that has been
44 * tailored for use as a search entry.
45 *
46 * It will show an inactive symbolic “find” icon when the search
47 * entry is empty, and a symbolic “clear” icon when there is text.
48 * Clicking on the “clear” icon will empty the search entry.
49 *
50 * Note that the search/clear icon is shown using a secondary
51 * icon, and thus does not work if you are using the secondary
52 * icon position for some other purpose.
53 *
54 * To make filtering appear more reactive, it is a good idea to
55 * not react to every change in the entry text immediately, but
56 * only after a short delay. To support this, #CtkSearchEntry
57 * emits the #CtkSearchEntry::search-changed signal which can
58 * be used instead of the #CtkEditable::changed signal.
59 *
60 * The #CtkSearchEntry::previous-match, #CtkSearchEntry::next-match
61 * and #CtkSearchEntry::stop-search signals can be used to implement
62 * moving between search results and ending the search.
63 *
64 * Often, CtkSearchEntry will be fed events by means of being
65 * placed inside a #CtkSearchBar. If that is not the case,
66 * you can use ctk_search_entry_handle_event() to pass events.
67 *
68 * Since: 3.6
