/**
* SECTION:gtkfilechooser
* @Short_description: File chooser interface used by GtkFileChooserWidget and GtkFileChooserDialog
* @Title: GtkFileChooser
* @See_also: #GtkFileChooserDialog, #GtkFileChooserWidget, #GtkFileChooserButton
*
* #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:
* <variablelist>
* <varlistentry>
* <term>Bookmarks</term>
* <listitem>
* are created by the user, by dragging folders from the
* right pane to the left pane, or by using the "Add". Bookmarks
* can be renamed and deleted by the user.
* </listitem>
* </varlistentry>
* <varlistentry>
* <term>Shortcuts</term>
* <listitem>
* can be provided by the application or by the underlying filesystem
* abstraction (e.g. both the gnome-vfs and the Windows filesystems
* provide "Desktop" shortcuts). Shortcuts cannot be modified by the
* user.
* </listitem>
* </varlistentry>
* <varlistentry>
* <term>Volumes</term>
* <listitem>
* are provided by the underlying filesystem abstraction. They are
* the "roots" of the filesystem.
* </listitem>
* </varlistentry>
* </variablelist>
* <refsect2 id="gtkfilechooser-encodings">
* <title>File Names and Encodings</title>
* 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.
* <note>
* 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.
* </note>

* <refsect2 id="gtkfilechooser-preview">
* <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.

* <title>Adding Extra Widgets</title>
* <para>
* You can add extra widgets to a file chooser to provide options
* that are not present in the default design. For example, you
* can add a toggle button to give the user the option to open a
* file in read-only mode. You can use
* gtk_file_chooser_set_extra_widget() to insert additional
* widgets in a file chooser.
* </para>

* <note>
* If you want to set more than one extra widget in the file
* chooser, you can a container such as a #GtkVBox or a #GtkTable
* and include your widgets in it. Then, set the container as
* the whole extra widget.

* GtkFileChooser::confirm-overwrite:
* @chooser: the object which received the signal.
*
* 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.
*
* Most applications just need to turn on the
* #GtkFileChooser:do-overwrite-confirmation 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 #GtkFileChooser::confirm-overwrite
* signal.
*
* 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
