<p>
<code class="classname">Menu</code>s are normally just added to a window, but they can
also be displayed temporarily as the result of a mouse button click. For
instance, a context menu might be displayed when the user clicks their right
mouse button.
</p>

<p>For instance:
</p>
<pre class="programlisting"><code class="code">Glib::ustring ui_info =
  "&lt;interface&gt;"
  "  &lt;menu id='menu-examplepopup'&gt;"
  "    &lt;section&gt;"
  "      &lt;item&gt;"
  "        &lt;attribute name='label' translatable='yes'&gt;Edit&lt;/attribute&gt;"
  "        &lt;attribute name='action'&gt;examplepopup.edit&lt;/attribute&gt;"
  "      &lt;/item&gt;"
  "      &lt;item&gt;"
  "        &lt;attribute name='label' translatable='yes'&gt;Process&lt;/attribute&gt;"
  "        &lt;attribute name='action'&gt;examplepopup.process&lt;/attribute&gt;"
  "      &lt;/item&gt;"
  "      &lt;item&gt;"
  "        &lt;attribute name='label' translatable='yes'&gt;Remove&lt;/attribute&gt;"
  "        &lt;attribute name='action'&gt;examplepopup.remove&lt;/attribute&gt;"
  "      &lt;/item&gt;"
  "    &lt;/section&gt;"
  "  &lt;/menu&gt;"
  "&lt;/interface&gt;";

m_refBuilder-&gt;add_from_string(ui_info);

auto gmenu = m_refBuilder-&gt;get_object&lt;Gio::Menu&gt;("menu-examplepopup");
m_MenuPopup.set_menu_model(gmenu);
</code></pre>

<p>
To show the popup menu, use  a <code class="classname">Gtk::GestureClick</code>
and connect to its <code class="literal">pressed</code> signal. In the signal handler,
use <code class="classname">Gtk::PopoverMenu</code>'s
<code class="methodname">popup()</code> method. For instance:
</p>
<pre class="programlisting"><code class="code">void ExampleWindow::on_label_pressed(int /* n_press */, double x, double y)
{
  const Gdk::Rectangle rect(x, y, 1, 1);
  m_MenuPopup.set_pointing_to(rect);
  m_MenuPopup.popup();
}</code></pre>
