         * To make constructing a #GtkAboutDialog as convenient as possible, you can

         * application, but in order to ensure proper translation of the title,
         * applications should set the title property explicitly when constructing
         * a #GtkAboutDialog, as shown in the following example:
         * <informalexample><programlisting>
         * gtk_show_about_dialog (NULL,

         * The #GtkAccelLabel widget is a subclass of #GtkLabel that also displays an
         * accelerator key on the right of the label text, e.g. 'Ctl+S'.
         * It is commonly used in menus to show the keyboard short-cuts for commands.
         *
         * The accelerator key to display is not set explicitly.
         * Instead, the #GtkAccelLabel displays the accelerators which have been added to
         * a particular widget. This widget is set by calling
         * gtk_accel_label_set_accel_widget().
         *
         * For example, a #GtkMenuItem widget may have an accelerator added to emit the
         * "activate" signal when the 'Ctl+S' key combination is pressed.
         * A #GtkAccelLabel is created and added to the #GtkMenuItem, and
         * gtk_accel_label_set_accel_widget() is called with the #GtkMenuItem as the
         * second argument. The #GtkAccelLabel will now display 'Ctl+S' after its label.
         *
         * Note that creating a #GtkMenuItem with gtk_menu_item_new_with_label() (or
         * one of the similar functions for #GtkCheckMenuItem and #GtkRadioMenuItem)
         * automatically adds a #GtkAccelLabel to the #GtkMenuItem and calls
         * gtk_accel_label_set_accel_widget() to set it up for you.
         *
         * A #GtkAccelLabel will only display accelerators which have %GTK_ACCEL_VISIBLE
         * set (see #GtkAccelFlags).
         * A #GtkAccelLabel can display multiple accelerators and even signal names,
         * though it is almost always used to display just one accelerator key.
         * <example>
         * <title>Creating a simple menu item with an accelerator key.</title>

         * #GtkIMContext defines the interface for GTK+ input methods. An input method
         * is used by GTK+ text input widgets like #GtkEntry to map from key events to
         * Unicode character strings.
         *
         * The user may change the current input method via a context menu, unless the
         * #GtkSettings:gtk-show-input-method-menu GtkSettings property is set to FALSE.
         * The default input method can be set programmatically via the
         * #GtkSettings:gtk-im-module GtkSettings property. Alternatively, you may set
         * the GTK_IM_MODULE environment variable as documented in #gtk-running.
         *
         * The #GtkEntry #GtkEntry:im-module and #GtkTextView #GtkTextView:im-module
         * properties may also be used to set input methods for specific widget
         * instances. For instance, a certain entry widget might be expected to contain
         * certain characters which would be easier to input with a certain input
         * method.
         *
         * An input method may consume multiple key events in sequence and finally
         * output the composed result. This is called preediting, and an input method
         * may provide feedback about this process by displaying the intermediate
         * composition states as preedit text. For instance, the default GTK+ input
         * method implements the input of arbitrary Unicode code points by holding down
         * the Control and Shift keys and then typing "U" followed by the hexadecimal
         * digits of the code point.  When releasing the Control and Shift keys,
         * preediting ends and the character is inserted as text. Ctrl+Shift+u20AC for
         * example results in the € sign.
         *
         * Additional input methods can be made available for use by GTK+ widgets as
         * loadable modules. An input method module is a small shared library which
         * implements a subclass of #GtkIMContext or #GtkIMContextSimple and exports
         * these four functions:
         *
         * <informalexample><programlisting>
         * void im_module_init(#GTypeModule *module);
         * </programlisting></informalexample>
         * This function should register the #GType of the #GtkIMContext subclass which
         * implements the input method by means of g_type_module_register_type(). Note
         * that g_type_register_static() cannot be used as the type needs to be
         * registered dynamically.
         *
         * <informalexample><programlisting>
         * void im_module_exit(void);
         * </programlisting></informalexample>
         * Here goes any cleanup code your input method might require on module unload.
         *
         * <informalexample><programlisting>
         * void im_module_list(const #GtkIMContextInfo ***contexts, int *n_contexts)
         * {
         *   *contexts = info_list;
         *   *n_contexts = G_N_ELEMENTS (info_list);
         * }
         * </programlisting></informalexample>
         * This function returns the list of input methods provided by the module. The
         * example implementation above shows a common solution and simply returns a
         * pointer to statically defined array of #GtkIMContextInfo items for each
         * provided input method.
         *
         * <informalexample><programlisting>
         * #GtkIMContext * im_module_create(const #gchar *context_id);
         * </programlisting></informalexample>

         * #GtkIMContext subclass identified by `context_id`. The context ID is the same
         * as specified in the #GtkIMContextInfo array returned by im_module_list().
         *
         * After a new loadable input method module has been installed on the system,

         * There's a convenience function to do this, gtk_image_new_from_file(),
         * used as follows:
         * <informalexample><programlisting>
         *   GtkWidget *image;
         *   image = gtk_image_new_from_file ("myfile.png");
         * </programlisting></informalexample>
         * If the file isn't loaded successfully, the image will contain a
         * "broken image" icon similar to that used in many web browsers.
         * If you want to handle errors in loading the file yourself,
         * for example by displaying an error message, then load the image with
         * gdk_pixbuf_new_from_file(), then create the #GtkImage with
         * gtk_image_new_from_pixbuf().
         *
         * The image file may contain an animation, if so the #GtkImage will
         * display an animation (#GdkPixbufAnimation) instead of a static image.
         *
         * #GtkImage is a subclass of #GtkMisc, which implies that you can
         * align it (center, left, right) and add padding to it, using
         * #GtkMisc methods.
         *
         * #GtkImage is a "no window" widget (has no #GdkWindow of its own),
         * so by default does not receive events. If you want to receive events
         * on the image, such as button clicks, place the image inside a
         * #GtkEventBox, then connect to the event signals on the event box.

         *
         * When handling events on the event box, keep in mind that coordinates
         * in the image may be different from event box coordinates due to
         * the alignment and padding settings on the image (see #GtkMisc).
         * The simplest way to solve this is to set the alignment to 0.0
         * (left/top), and set the padding to zero. Then the origin of
         * the image will be the same as the origin of the event box.
         *
         * Sometimes an application will want to avoid depending on external data
         * files, such as image files. GTK+ comes with a program to avoid this,
         * called <application>gdk-pixbuf-csource</application>. This program
         * allows you to convert an image into a C variable declaration, which
         * can then be loaded into a #GdkPixbuf using
         * gdk_pixbuf_new_from_inline().

         * must make sure that the socket widget is not destroyed

         * it returns a non-%NULL value, then the plug has been
         * successfully created inside of the socket.
         *
         * When GTK+ is notified that the embedded window has been
         * destroyed, then it will destroy the socket as well. You
         * should always, therefore, be prepared for your sockets

         * is running. To prevent this from happening, you can
         * connect to the #GtkSocket::plug-removed signal.
         *
         * The communication between a #GtkSocket and a #GtkPlug follows the
         * <ulink url="http://www.freedesktop.org/Standards/xembed-spec">XEmbed</ulink>
         * protocol. This protocol has also been implemented in other toolkits, e.g.
         * <application>Qt</application>, allowing the same level of integration
         * when embedding a <application>Qt</application> widget in GTK or vice versa.
         *
         * A socket can also be used to swallow arbitrary
         * pre-existing top-level windows using gtk_socket_steal(),
         * though the integration when this is done will not be as close
         * as between a #GtkPlug and a #GtkSocket.

             * gtk_window_get_position() is not 100% reliable because the X Window System

             *
             * Moreover, nearly all window managers are historically broken with
             * respect to their handling of window gravity. So moving a window to
             * its current position as returned by gtk_window_get_position() tends
             * to result in moving the window slightly. Window managers are
             * slowly getting better over time.
             *
             * If a window has gravity #GDK_GRAVITY_STATIC the window manager
             * frame is not relevant, and thus gtk_window_get_position() will

             * gravity to do things like place a window in a corner of the screen,

             * "configure-event" on the window and adjust your size-dependent

             * the window onscreen, there may be a better way. The preferred

             * e.g. center dialogs. Also, if you set the transient parent of
             * dialogs with gtk_window_set_transient_for() window managers
