## Prerequisites

GtkRecentChooser requires GObject.

## Known Implementations

GtkRecentChooser is implemented by GtkRecentAction, GtkRecentChooserDialog, GtkRecentChooserMenu and GtkRecentChooserWidget.

## Includes

    #include <gtk/gtk.h>

## Description

GtkRecentChooser is an interface that can be implemented by widgets displaying the list of recently used files. In GTK+, the main objects that implement this interface are GtkRecentChooserWidget, GtkRecentChooserDialog and GtkRecentChooserMenu.
