20 * SECTION:ctkrecentfilter
21 * @Short_Description: A filter for selecting a subset of recently used files
22 * @Title: CtkRecentFilter
23 *
24 * A #CtkRecentFilter can be used to restrict the files being shown
25 * in a #CtkRecentChooser. Files can be filtered based on their name
26 * (with ctk_recent_filter_add_pattern()), on their mime type (with
27 * ctk_file_filter_add_mime_type()), on the application that has
28 * registered them (with ctk_recent_filter_add_application()), or by
29 * a custom filter function (with ctk_recent_filter_add_custom()).
30 *
31 * Filtering by mime type handles aliasing and subclassing of mime
32 * types; e.g. a filter for text/plain also matches a file with mime
33 * type application/rtf, since application/rtf is a subclass of text/plain.
34 * Note that #CtkRecentFilter allows wildcards for the subtype of a
35 * mime type, so you can e.g. filter for image/\*.
36 *
37 * Normally, filters are used by adding them to a #CtkRecentChooser,
38 * see ctk_recent_chooser_add_filter(), but it is also possible to
39 * manually use a filter on a file with ctk_recent_filter_filter().
40 *
41 * Recently used files are supported since CTK+ 2.10.
42 *
43 * ## CtkRecentFilter as CtkBuildable
44 *
45 * The CtkRecentFilter implementation of the CtkBuildable interface
46 * supports adding rules using the <mime-types>, <patterns> and
47 * <applications> elements and listing the rules within. Specifying
48 * a <mime-type>, <pattern> or <application> has the same effect as
49 * calling ctk_recent_filter_add_mime_type(),
50 * ctk_recent_filter_add_pattern() or ctk_recent_filter_add_application().
51 *
52 * An example of a UI definition fragment specifying CtkRecentFilter rules:
53 * |[
54 * <object class="CtkRecentFilter">
55 * <mime-types>
56 * <mime-type>text/plain</mime-type>
57 * <mime-type>image/png</mime-type>
58 * </mime-types>
59 * <patterns>
60 * <pattern>*.txt</pattern>
61 * <pattern>*.png</pattern>
62 * </patterns>
63 * <applications>
64 * <application>gimp</application>
65 * <application>gedit</application>
66 * <application>glade</application>
67 * </applications>
68 * </object>
