File chooser interface used by GtkFileChooserWidget and GtkFileChooserDialog

    <para>
      #GtkFileChooser is an interface that can be implemented by file
      selection widgets.  In GTK+, the main objects that implement this
      interface are #GtkFileChooserWidget, #GtkFileChooserDialog, and
      #GtkFileChooserButton.  You do not need to write an object that
      implements the #GtkFileChooser interface unless you are trying to
      adapt an existing file selector to expose a standard programming
      interface.

      #GtkFileChooser allows for shortcuts to various places in the filesystem.
      In the default implementation these are displayed in the left pane. It
      may be a bit confusing at first taht these shortcuts come from various 
      sources and in various flavours, so lets explain the terminology here:

      <title>File Names and Encodings</title>

      <para>
	When the user is finished selecting files in a
	#GtkFileChooser, your program can get the selected names
	either as filenames or as URIs.  For URIs, the normal escaping
	rules are applied if the URI contains non-ASCII characters.
	However, filenames are <emphasis>always</emphasis> returned in
	the character set specified by the
	<envar>G_FILENAME_ENCODING</envar> environment variable.
	Please see the Glib documentation for more details about this
	variable.
      </para>

      <important>
	<para>
	  This means that while you can pass the result of
	  gtk_file_chooser_get_filename() to
	  <function>open(2)</function> or
	  <function>fopen(3)</function>, you may not be able to
	  directly set it as the text of a #GtkLabel widget unless you
	  convert it first to UTF-8, which all GTK+ widgets expect.
	  You should use g_filename_to_utf8() to convert filenames
	  into strings that can be passed to GTK+ widgets.

      <title>Adding a Preview Widget</title>

      <para>
	You can add a custom preview widget to a file chooser and then
	get notification about when the preview needs to be updated.
	To install a preview widget, use
	gtk_file_chooser_set_preview_widget().  Then, connect to the
	#GtkFileChooser::update-preview signal to get notified when
	you need to update the contents of the preview.
      </para>

      <para>
	Your callback should use
	gtk_file_chooser_get_preview_filename() to see what needs
	previewing.  Once you have generated the preview for the
	corresponding file, you must call
	gtk_file_chooser_set_preview_widget_active() with a boolean
	flag that indicates whether your callback could successfully
	generate a preview.

	You can add extra widgets to a file chooser to provide options
	that are not present in the default design.  For example, you

<!-- ##### SIGNAL GtkFileChooser::confirm-overwrite ##### -->
    <para>
      This signal gets emitted whenever it is appropriate to present a
      confirmation dialog when the user has selected a file name that
      already exists.  The signal only gets emitted when the file
      chooser is in #GTK_FILE_CHOOSER_ACTION_SAVE mode.
    </para>

    <para>
      Most applications just need to turn on the <link
      linkend="GtkFileChooser--do-overwrite-confirmation">do-overwrite-confirmation</link>
      property (or call the
      gtk_file_chooser_set_do_overwrite_confirmation() function), and
      they will automatically get a stock confirmation dialog.
      Applications which need to customize this behavior should do
      that, and also connect to the <symbol>confirm-overwrite</symbol>
      signal.
    </para>

    <para>
      A signal handler for this signal must return a
      #GtkFileChooserConfirmation value, which indicates the action to
      take.  If the handler determines that the user wants to select a
      different filename, it should return
      #GTK_FILE_CHOOSER_CONFIRMATION_SELECT_AGAIN.  If it determines
      that the user is satisfied with his choice of file name, it
      should return #GTK_FILE_CHOOSER_CONFIRMATION_ACCEPT_FILENAME.
      On the other hand, if it determines that the stock confirmation
      dialog should be used, it should return
      #GTK_FILE_CHOOSER_CONFIRMATION_CONFIRM.  The following example
      illustrates this.

@GTK_FILE_CHOOSER_ACTION_OPEN: Indicates open mode.  The file chooser
    will only let the user pick an existing file.
@GTK_FILE_CHOOSER_ACTION_SAVE: Indicates save mode.  The file chooser
    will let the user pick an existing file, or type in a new
    filename.
@GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER: Indicates an Open mode for
