</h1><div class="doc"><p>The <code><a href="Graphics-UI-Gtk-Layout-Fixed.html#t:Fixed">Fixed</a></code> widget is a container which can place child widgets at fixed
positions and with fixed sizes, given in pixels. <code><a href="Graphics-UI-Gtk-Layout-Fixed.html#t:Fixed">Fixed</a></code> performs no
automatic layout management.
</p><p>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 <code><a href="Graphics-UI-Gtk-Layout-Fixed.html#t:Fixed">Fixed</a></code>, the following things will result in
truncated text, overlapping widgets, and other display bugs:
</p><ul><li> Themes, which may change widget sizes.
</li><li> 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.
</li><li> Translation of text into other languages changes its size. Also,
display of non-English text will use a different font in many cases.
</li></ul><p>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 <code><a href="Graphics-UI-Gtk-Layout-Fixed.html#t:Fixed">Fixed</a></code>. So your application will not be usable in
right-to-left languages.
</p><p>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.
</p><p>If you know none of these things are an issue for your application, and
prefer the simplicity of <code><a href="Graphics-UI-Gtk-Layout-Fixed.html#t:Fixed">Fixed</a></code>, by all means use the widget. But you
should be aware of the tradeoffs.
