+/**
+ * SECTION:gtkfixed
+ * @Short_description: A container which allows you to position
+ * widgets at fixed coordinates
+ * @Title: GtkFixed
+ *
+ * The #GtkFixed widget is a container which can place child widgets
+ * at fixed positions and with fixed sizes, given in pixels. #GtkFixed
+ * performs no automatic layout management.
+ *
+ * For most applications, you should not use this container! It keeps
+ * you from having to learn about the other GTK+ containers, but it
+ * results in broken applications. With #GtkFixed, the following
+ * things will result in truncated text, overlapping widgets, and
+ * other display bugs:
+ * <itemizedlist>
+ * <listitem><para>
+ * Themes, which may change widget sizes.
+ * </para></listitem>
+ * <listitem><para>
+ * Fonts other than the one you used to write the app will of course
+ * change the size of widgets containing text; keep in mind that
+ * users may use a larger font because of difficulty reading the
+ * default, or they may be using Windows or the framebuffer port of
+ * GTK+, where different fonts are available.
+ * </para></listitem>
+ * <listitem><para>
+ * Translation of text into other languages changes its size. Also,
+ * display of non-English text will use a different font in many
+ * cases.
+ * </para></listitem>
+ * </itemizedlist>
+ *
+ * In addition, the fixed widget can't properly be mirrored in
+ * right-to-left languages such as Hebrew and Arabic. i.e. normally
+ * GTK+ will flip the interface to put labels to the right of the
+ * thing they label, but it can't do that with #GtkFixed. So your
+ * application will not be usable in right-to-left languages.
+ *
+ * Finally, fixed positioning makes it kind of annoying to add/remove
+ * GUI elements, since you have to reposition all the other
+ * elements. This is a long-term maintenance problem for your
+ * application.
+ *
+ * If you know none of these things are an issue for your application,
+ * and prefer the simplicity of #GtkFixed, by all means use the
+ * widget. But you should be aware of the tradeoffs.
