commit f746afc794f026170a6abc40d86b002dd105d66a
Author: Javier Jardón <jjardon gnome org>
Date:   Mon Dec 21 06:05:51 2009 +0100

    Move documentation to inline comments: GtkFileChooser
    
    Also, use Gtk-Doc markup to improve documentation
    cross-references.

+ * 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.

+ * <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.

+ * <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

+   * 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
+   * %GTK_FILE_CHOOSER_CONFIRMATION_CONFIRM. The following example
+   * illustrates this.
