Public Member Functions | |
virtual | ~RecentFilter () |
GtkRecentFilter* | gobj () |
Provides access to the underlying C GObject. | |
const GtkRecentFilter* | gobj () const |
Provides access to the underlying C GObject. | |
GtkRecentFilter* | gobj_copy () |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs. | |

Sets the human-readable name of the filter; this is the string that will be displayed in the recently used resources selector user interface if there is a selectable list of filters. | |
Glib::ustring | get_name () const |
Gets the human-readable name for the filter. | |
void | add_mime_type (const Glib::ustring& mime_type) |
Adds a rule that allows resources based on their registered MIME type. | |
void | add_pattern (const Glib::ustring& pattern) |
Adds a rule that allows resources based on a pattern matching their display name. | |
void | add_pixbuf_formats () |
Adds a rule allowing image files in the formats supported by GdkPixbuf. | |

Adds a rule that allows resources based on the name of the application that has registered them. | |
void | add_group (const Glib::ustring& group) |
Adds a rule that allows resources based on the name of the group to which they belong. | |

RecentFilter can be used to restrict the files being shown in a RecentChooser.
Files can be filtered based on their name (with add_pattern()), on their mime type (with add_mime_type()), on the application that has registered them (with add_application()), or by a custom filter function (with add_custom()).
Filtering by mime type handles aliasing and subclassing of mime types; e.g. a filter for text/plain also matches a file with mime type application/rtf, since application/rtf is a subclass of text/plain. Note that RecentFilter allows wildcards for the subtype of a mime type, so you can e.g. filter for image/*.
Normally, filters are used by adding them to a RecentChooser, see RecentChooser::add_filter(), but it is also possible to manually use a filter on a file with filter().
