* SECTION:gtkrecentchooserdialog
* @Short_description: Displays recently used files in a dialog
* @Title: GtkRecentChooserDialog
* @See_also:#GtkRecentChooser, #GtkDialog
*
* #GtkRecentChooserDialog is a dialog box suitable for displaying the recently
* used documents. This widgets works by putting a #GtkRecentChooserWidget inside
* a #GtkDialog. It exposes the #GtkRecentChooserIface interface, so you can use
* all the #GtkRecentChooser functions on the recent chooser dialog as well as
* those for #GtkDialog.
*
* Note that #GtkRecentChooserDialog does not have any methods of its own.
* Instead, you should use the functions that work on a #GtkRecentChooser.
*
* <example id="gtkrecentchooser-typical-usage">
* <title>Typical usage</title>
* In the simplest of cases, you can use the following code to use
* a #GtkRecentChooserDialog to select a recently used file:
* <programlisting>
* GtkWidget *dialog;
*
* dialog = gtk_recent_chooser_dialog_new ("Recent Documents",
* parent_window,
* GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
* GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT,
* NULL);
*
* if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
* {
* GtkRecentInfo *info;
*
* info = gtk_recent_chooser_get_current_item (GTK_RECENT_CHOOSER (dialog));
* open_file (gtk_recent_info_get_uri (info));
* gtk_recent_info_unref (info);
* }
*
* gtk_widget_destroy (dialog);
* </programlisting>
* </example>
*
* Recently used files are supported since GTK+ 2.10.
