## Detailed Description

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().

Since gtkmm 2.10:

## Member Typedef Documentation

typedef sigc::slot<bool, const Info&> Gtk::RecentFilter::SlotCustom

For instance, bool on_custom(const Gtk::RecentFilter::Info& filter_info);.

## Constructor & Destructor Documentation

virtual Gtk::RecentFilter::~RecentFilter | ( |  | ) |

virtual

Gtk::RecentFilter::RecentFilter | ( |  | ) |

protected

## Member Function Documentation

void Gtk::RecentFilter::add_age | ( | int | days | ) |

Adds a rule that allows resources based on their age - that is, the number of days elapsed since they were last modified.

Since gtkmm 2.10:

Parameters

  days | Number of days.

void Gtk::RecentFilter::add_application | ( | const Glib::ustring & | application | ) |

Adds a rule that allows resources based on the name of the application that has registered them.

Since gtkmm 2.10:

Parameters

  application | An application name.

void Gtk::RecentFilter::add_custom | ( | RecentFilterFlags | needed,
|  | const SlotCustom& | slot
| ) |  |

void Gtk::RecentFilter::add_group | ( | const Glib::ustring & | group | ) |

Adds a rule that allows resources based on the name of the group to which they belong.

Since gtkmm 2.10:

Parameters

  group | A group name.

void Gtk::RecentFilter::add_mime_type | ( | const Glib::ustring & | mime_type | ) |

Adds a rule that allows resources based on their registered MIME type.

Since gtkmm 2.10:

Parameters

  mime_type | A MIME type.

void Gtk::RecentFilter::add_pattern | ( | const Glib::ustring & | pattern | ) |

Adds a rule that allows resources based on a pattern matching their display name.

Since gtkmm 2.10:

Parameters

  pattern | A file pattern.

void Gtk::RecentFilter::add_pixbuf_formats | ( |  | ) |

Adds a rule allowing image files in the formats supported by GdkPixbuf.

Since gtkmm 2.10:

static Glib::RefPtr<RecentFilter> Gtk::RecentFilter::create | ( |  | ) |

static

Glib::ustring Gtk::RecentFilter::get_name | ( |  | ) | const

Gets the human-readable name for the filter.

See set_name().

Since gtkmm 2.10:

Returns
  The name of the filter, or `0`. The returned string is owned by the filter object and should not be freed.

RecentFilterFlags Gtk::RecentFilter::get_needed | ( |  | ) | const

Gets the fields that need to be filled in for the Gtk::RecentFilterInfo passed to filter()

This function will not typically be used by applications; it is intended principally for use in the implementation of Gtk::RecentChooser.

Since gtkmm 2.10:

Returns
  Bitfield of flags indicating needed fields when calling filter().

static GType Gtk::RecentFilter::get_type | ( |  | ) |

static

Get the GType for this class, for use with the underlying GObject type system.

GtkRecentFilter* Gtk::RecentFilter::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const GtkRecentFilter* Gtk::RecentFilter::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

GtkRecentFilter* Gtk::RecentFilter::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

void Gtk::RecentFilter::set_name | ( | const Glib::ustring & | name | ) |

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.

Since gtkmm 2.10:

Parameters

  name | Then human readable name of filter.

## Friends And Related Function Documentation

Glib::RefPtr< Gtk::RecentFilter > wrap | ( | GtkRecentFilter * | object,
|  | bool | take_copy = `false`
| ) |  |

related

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
