GtkFixed
<!-- ##### SECTION Short_Description ##### -->
a container which supports fixed sizes and positions of its children.
a container which allows you to position widgets at fixed coordinates
<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkFixed widget is a container which can place child widgets at fixed
positions and with fixed sizes, given in pixels.
positions and with fixed sizes, given in pixels. #GtkFixed performs no
automatic layout management.
</para>
<para>
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.
