/**
 * The #GtkFileChooserButton is a widget that lets the user select a
 * file.  It implements the #GtkFileChooser interface.  Visually, it is a
 * file name with a button to bring up a #GtkFileChooserDialog.
 * The user can then use that dialog to change the file associated with
 * that button.  This widget does not support setting the
 * #GtkFileChooser:select-multiple property to %TRUE.
 * 
 * ## Create a button to let the user select a file in /etc
 * 
 * |[<!-- language="C" -->

 * GTK_FILE_CHOOSER_ACTION_OPEN);
 * gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button),
 * "/etc");
 * }
 * ]|
 * 
 * The #GtkFileChooserButton supports the #GtkFileChooserActions
 * %GTK_FILE_CHOOSER_ACTION_OPEN and %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
 * 
 * > The #GtkFileChooserButton will ellipsize the label, and will thus
 * > request little horizontal space.  To give the button more space,
 * > you should call gtk_widget_get_preferred_size(),
 * > gtk_file_chooser_button_set_width_chars(), or pack the button in
 * > such a way that other interface elements give space to the
 * > widget.
