<a href="/usr/share/gtk-doc/html/gtk3/GtkMenu.html#gtk-menu-popup"><code class="function">gtk_menu_popup()</code></a>, this function will verify that the menu has been mapped
or will keep trying for up to 250ms. It will also return a value indicating
whether the menu was eventually mapped or not. Following is an excerpt from
the GTK+ Documentation on <a href="/usr/share/gtk-doc/html/gtk3/GtkMenu.html#GtkMenu-struct"><span class="type">GtkMenu</span></a>.</p>
<p>Displays a menu and makes it available for selection.</p>
<p>Applications can use this function to display context-sensitive menus, and will
typically supply <a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> for the <em class="parameter"><code>parent_menu_shell</code></em>
, <em class="parameter"><code>parent_menu_item</code></em>
, <em class="parameter"><code>func</code></em>
and
<em class="parameter"><code>data</code></em>
parameters. The default menu positioning function will position the menu
at the current mouse cursor position.</p>
<p>The <em class="parameter"><code>button</code></em>
parameter should be the mouse button pressed to initiate the menu
popup. If the menu popup was initiated by something other than a mouse button
press, such as a mouse button release or a keypress, button should be 0.</p>
<p>The <em class="parameter"><code>activate_time</code></em>
parameter is used to conflict-resolve initiation of concurrent
requests for mouse/keyboard grab requests. To function properly, this needs to
be the timestamp of the user event (such as a mouse click or key press) that
caused the initiation of the popup. Only if no such event is available,
<a href="/usr/share/gtk-doc/html/gtk3/gtk3-General.html#gtk-get-current-event-time"><code class="function">gtk_get_current_event_time()</code></a> can be used instead.</p>
