## Description

## Functions

### gtk_recent_manager_new ()

    GtkRecentManager *
    gtk_recent_manager_new (void);

Creates a new recent manager object. Recent manager objects are used to handle the list of recently used resources. A GtkRecentManager object monitors the recently used resources list, and emits the "changed" signal each time something inside the list changes.

GtkRecentManager objects are expensive: be sure to create them only when needed. You should use `gtk_recent_manager_get_default()` instead.

#### Returns

A newly created GtkRecentManager object.

Since: 2.10

### gtk_recent_manager_get_default ()

    GtkRecentManager *
    gtk_recent_manager_get_default (void);

Gets a unique instance of GtkRecentManager, that you can share in your application without caring about memory management. The returned instance will be freed when you application terminates.

#### Returns

A unique GtkRecentManager. Do not ref or unref it.

[transfer none]

Since: 2.10

### gtk_recent_manager_get_for_screen ()

    GtkRecentManager *
    gtk_recent_manager_get_for_screen (GdkScreen *screen);

`gtk_recent_manager_get_for_screen` has been deprecated since version 2.12 and should not be used in newly-written code.

This function has been deprecated and should not be used in newly written code. Calling this function is equivalent to calling `gtk_recent_manager_get_default()`.

Gets the recent manager object associated with `screen` ; if this function has not previously been called for the given screen, a new recent manager object will be created and associated with the screen. Recent manager objects are fairly expensive to create, so using this function is usually a better choice than calling `gtk_recent_manager_new()` and setting the screen yourself; by using this function a single recent manager object will be shared between users.

#### Parameters

screen | a GdkScreen |

#### Returns

A unique GtkRecentManager associated with the given screen. This recent manager is associated to the with the screen and can be used as long as the screen is open. Do not ref or unref it.

Since: 2.10

### gtk_recent_manager_set_screen ()

    void
    gtk_recent_manager_set_screen (GtkRecentManager *manager,
                                   GdkScreen *screen);

`gtk_recent_manager_set_screen` has been deprecated since version 2.12 and should not be used in newly-written code.

This function has been deprecated and should not be used in newly written code. Calling this function has no effect.

Sets the screen for a recent manager; the screen is used to track the user's currently configured recently used documents storage.

#### Parameters

manager | a GtkRecentManager |
screen | a GdkScreen |

Since: 2.10

### gtk_recent_manager_add_item ()

    gboolean
    gtk_recent_manager_add_item (GtkRecentManager *manager,
                                 const gchar *uri);

Adds a new resource, pointed by `uri` , into the recently used resources list.

This function automatically retrieves some of the needed metadata and setting other metadata to common default values; it then feeds the data to `gtk_recent_manager_add_full()`.

See `gtk_recent_manager_add_full()` if you want to explicitly define the metadata for the resource pointed by `uri` .

#### Parameters

manager | a GtkRecentManager |
uri | a valid URI |

#### Returns

`TRUE` if the new item was successfully added to the recently used resources list

Since: 2.10

### gtk_recent_manager_add_full ()

    gboolean
    gtk_recent_manager_add_full (GtkRecentManager *manager,
                                 const gchar *uri,
                                 const GtkRecentData *recent_data);

Adds a new resource, pointed by `uri` , into the recently used resources list, using the metadata specified inside the GtkRecentData structure passed in `recent_data` .

The passed URI will be used to identify this resource inside the list.

In order to register the new recently used resource, metadata about the resource must be passed as well as the URI; the metadata is stored in a GtkRecentData structure, which must contain the MIME type of the resource pointed by the URI; the name of the application that is registering the item, and a command line to be used when launching the item.

Optionally, a GtkRecentData structure might contain a UTF-8 string to be used when viewing the item instead of the last component of the URI; a short description of the item; whether the item should be considered private - that is, should be displayed only by the applications that have registered it.

#### Parameters

manager | a GtkRecentManager |
uri | a valid URI |
recent_data | metadata of the resource |

#### Returns

`TRUE` if the new item was successfully added to the recently used resources list, `FALSE` otherwise.

Since: 2.10

### gtk_recent_manager_remove_item ()

#### Parameters

manager | a GtkRecentManager |
uri | the URI of the item you wish to remove |
error | return location for a GError, or `NULL`. | [allow-none]
