 GtkFixed

-a container which supports fixed sizes and positions of its children.

 The #GtkFixed widget is a container which can place child widgets at fixed
-positions and with fixed sizes, given in pixels.

+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>
+</para>
 
+<para>
+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.
+</para>
+
+<para>
+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.
+</para>
+
+<para>
+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.
