<title>Description</title>
<para>The <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link> widget is a
container that can place child widgets at fixed positions and with fixed
sizes, given in pixels. <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link> performs no
automatic layout management. For most applications, you should not use this
container! It keeps you from having to learn about the other PyGTK
containers, but it results in broken applications. With <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link>, the
following things will result in truncated text, overlapping widgets, and
other display bugs:</para>
<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 PyGTK, 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>In addition, the fixed widget can't properly be mirrored in
right-to-left languages such as Hebrew and Arabic. i.e. normally PyGTK will
flip the interface to put labels to the right of the thing they label, but
it can't do that with <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link>. So your
application will not be usable in right-to-left languages. Finally, fixed
positioning makes it kind of annoying to add and 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 <link
linkend="class-gtkfixed"><classname>gtk.Fixed</classname></link>, by all
means use the widget. But you should be aware of the tradeoffs.</para>
