<a name="GtkFixed.description"></a><h2>Description</h2>
<p>The <a class="link" href="GtkFixed.html" title="GtkFixed"><span class="type">GtkFixed</span></a> widget is a container which can place child widgets
at fixed positions and with fixed sizes, given in pixels. <a class="link" href="GtkFixed.html" title="GtkFixed"><span class="type">GtkFixed</span></a>
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 <a class="link" href="GtkFixed.html" title="GtkFixed"><span class="type">GtkFixed</span></a>, the following
things will result in truncated text, overlapping widgets, and
other display bugs:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>Themes, which may change widget sizes.</p></li>
<li class="listitem"><p>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.</p></li>
<li class="listitem"><p>Translation of text into other languages changes its size. Also,
display of non-English text will use a different font in many
cases.</p></li>
</ul></div>
<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 <a class="link" href="GtkFixed.html" title="GtkFixed"><span class="type">GtkFixed</span></a>. 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 <a class="link" href="GtkFixed.html" title="GtkFixed"><span class="type">GtkFixed</span></a>, by all means use the
widget. But you should be aware of the tradeoffs.</p>
