## Description

## Functions

### gwy_app_recent_file_list_new()

    GtkWidget *
    gwy_app_recent_file_list_new (void);

Creates document history browser.

There should be at most one document history browser, so this function fails if it already exists.

#### Returns

The newly created document history browser window.

### gwy_app_recent_file_list_update()

    void
    gwy_app_recent_file_list_update (GwyFile *data,
                                     const gchar *filename_utf8,
                                     const gchar *filename_sys,
                                     gint hint);

Moves `filename_utf8` to the first position in document history, possibly adding it if not present yet.

At least one of `filename_utf8` , `filename_sys` should be set.

#### Parameters

data | A data container corresponding to the file. |
filename_utf8 | A recent file to insert or move to the first position in document history, in UTF-8. |
filename_sys | A recent file to insert or move to the first position in document history, in GLib encoding. |
hint | Preferred channel id to use for thumbnail, pass 0 if no channel is specificaly preferred. |

### gwy_app_recent_file_list_load()

    gboolean
    gwy_app_recent_file_list_load (const gchar *filename);

Loads list of recently open files from `filename` .

Cannot be called more than once (at least not without doing `gwy_app_recent_file_list_free()` first). Must be called before any other document history function can be used, even if on a nonexistent file: use `NULL` as `filename` in that case.

#### Parameters

filename | Name of file containing list of recently open files. |

#### Returns

`TRUE` if the file was read successfully, `FALSE` otherwise.

### gwy_app_recent_file_list_save()

    gboolean
    gwy_app_recent_file_list_save (const gchar *filename);

Saves list of recently open files to `filename` .

#### Parameters

filename | Name of file to save the list of recently open files to. |

#### Returns

`TRUE` if the file was written successfully, `FALSE` otherwise.

### gwy_app_recent_file_list_free()

    void
    gwy_app_recent_file_list_free (void);

Frees all memory taken by recent file list.

Should not be called while the recent file menu still exists.

### gwy_app_recent_file_get_thumbnail()

    GdkPixbuf *
    gwy_app_recent_file_get_thumbnail (const gchar *filename_utf8);

Gets thumbnail of a recently open file.

#### Parameters

filename_utf8 | Name of a recent file, in UTF-8 encoding. |

#### Returns

The thumbnail as a new pixbuf or a pixbuf with a new reference. The caller must unreference it but not modify it. If a thumbnail can not be obtained, a fully transparent pixbuf is returned.
