<h1>Menus<a class="headerlink" href="#menus" title="Permalink to this headline">#</a></h1>
<p>In order to create <a class="reference external" href="https://developer.gnome.org/hig/patterns/controls/menus.html">menus</a> in GTK, you
have to describe the menu structure using the <code class="docutils literal notranslate"><span class="pre">GMenu</span></code> API; each menu item is
bound to a <a class="reference internal" href="actions.html"><span class="doc">GAction</span></a>.</p>
<p>It is possible to construct a menu model manually, using the GMenu APIs
directly. This is a somewhat painful:</p>

<h2>Primary menus<a class="headerlink" href="#primary-menus" title="Permalink to this headline">#</a></h2>
<p>A common pattern in modern user interfaces is to place a button, often with a
gears icon, in some prominent place (top-right), which will open a menu when
clicked. GTK comes with the :doc`GtkMenuButton &lt;/tutorials/beginners/menu_button&gt;`

<h2>Menu bars<a class="headerlink" href="#menu-bars" title="Permalink to this headline">#</a></h2>
<p>While uncommon in GNOME applications, it is still possible to create menu bars
by using <a class="reference external" href="https://docs.gtk.org/gtk4/class.PopoverMenuBar.html">GtkPopoverMenuBar</a>.</p>
</section>
<section id="context-menus">
<h2>Context menus<a class="headerlink" href="#context-menus" title="Permalink to this headline">#</a></h2>
<p>It is possible to create a freestanding menu from a menu model, using
<code class="docutils literal notranslate"><span class="pre">gtk_popover_menu_new_from_model()</span></code>. This menu can then be used as a context
menu on any widget. The actions you refer to in such a menu can come from the
application or window scopes. You can also introduce a more localized scope,
using <code class="docutils literal notranslate"><span class="pre">gtk_widget_insert_action_group()</span></code>. The actions from such a local scope
can be used in any menu that is attached below this local scope.</p>
</section>
<section id="icons">
<h2>Icons<a class="headerlink" href="#icons" title="Permalink to this headline">#</a></h2>
<p>In order to add an icon to a menu item, you must specify the <code class="docutils literal notranslate"><span class="pre">icon</span></code> attribute
on the items in your menu model; when the menu is constructed, the icon will be
properly placed in the UI. The expected value for this attribute is a serialized
GIcon. Luckily, the GIcon serialization format is convenient for this use—for
instance:</p>
<div class="highlight-xml notranslate"><div class="highlight"><pre><span></span><span class="nt">&lt;attribute</span> <span class="na">name=</span><span class="s">&quot;icon&quot;</span><span class="nt">&gt;</span>/path/to/my/icon.png<span class="nt">&lt;/attribute&gt;</span>
</pre></div>
</div>
<p>is a valid serialization for a <a class="reference external" href="https://docs.gtk.org/gio/class.FileIcon.html">GFileIcon</a>
for the file at the given path, and:</p>
<div class="highlight-xml notranslate"><div class="highlight"><pre><span></span><span class="nt">&lt;attribute</span> <span class="na">name=</span><span class="s">&quot;icon&quot;</span><span class="nt">&gt;</span>preferences-desktop-locale-symbolic<span class="nt">&lt;/attribute&gt;</span>
</pre></div>
</div>
<p>is a valid serialization for a <a class="reference external" href="https://docs.gtk.org/gio/class.ThemedIcon.html">GThemedIcon</a>
for the <code class="docutils literal notranslate"><span class="pre">preferences-desktop-locale-symbolic</span></code> symbolic icon.</p>
