<hr><a name="_details"></a><h2>Detailed Description</h2>
A GtkMenu C++ wrapper class.
<p>
A <a class="el" href="classGFC_1_1Gtk_1_1Menu.html">Menu</a> is a <a class="el" href="classGFC_1_1Gtk_1_1MenuShell.html">MenuShell</a> that implements a drop down menu consisting of a list of <a class="el" href="classGFC_1_1Gtk_1_1MenuItem.html">MenuItem</a> objects which can be navigated and activated by the user to perform application functions. A <a class="el" href="classGFC_1_1Gtk_1_1Menu.html">Menu</a> is most commonly dropped down by activating a <a class="el" href="classGFC_1_1Gtk_1_1MenuItem.html">MenuItem</a> in a <a class="el" href="classGFC_1_1Gtk_1_1MenuBar.html">MenuBar</a> or popped up by activating a <a class="el" href="classGFC_1_1Gtk_1_1MenuItem.html">MenuItem</a> in another <a class="el" href="classGFC_1_1Gtk_1_1Menu.html">Menu</a>. A <a class="el" href="classGFC_1_1Gtk_1_1Menu.html">Menu</a> can also be popped up by activating an OptionMenu. Other composite widgets such as the <a class="el" href="classGFC_1_1Gtk_1_1Notebook.html">Notebook</a> can pop up a <a class="el" href="classGFC_1_1Gtk_1_1Menu.html">Menu</a> as well. Applications can display a <a class="el" href="classGFC_1_1Gtk_1_1Menu.html">Menu</a> as a popup menu by calling the <a class="el" href="classGFC_1_1Gtk_1_1Menu.html#z640_0">popup()</a> method. The example below shows how an application can pop up a menu when the 3rd mouse button is pressed.<p>
<b>Example 1:</b> Connecting the popup signal handler. <div class="fragment"><pre> <span class="comment">// Declare a button_press_event handler in you window class.</span>
<span class="keywordtype">bool</span> on_button_press(GdkEventButton *event);
<span class="comment">// Then connect the window button_press_event to the popup signal handler.</span>
<a class="code" href="classGFC_1_1Gtk_1_1Widget.html#z1062_2">sig_button_press_event</a>().connect(slot(<span class="keyword">this</span>, &MyWindow::on_button_press));
</pre></div><p>
<b>Example 2:</b> A signal handler which displays a popup menu. <div class="fragment"><pre> <span class="comment">// Construct the popup menu somewhere first, then pop it up here.</span>
<span class="keywordtype">bool</span> MyWindow::on_button_press(GdkEventButton *event)
{
menu->popup(event->button, event->time);
<span class="keywordflow">return</span> <span class="keyword">true</span>;
}
</pre></div>There is a complete example of this in the menu example programs in the <examples/menu> subdirectory.

The main purpose of this method is to spare the programmer the inconvenience of having to call <a class="el" href="classGFC_1_1Gtk_1_1Menu.html#z640_8">set_accel_path()</a> on each menu item that should support runtime user changable accelerators. Instead, by just calling <a class="el" href="classGFC_1_1Gtk_1_1Menu.html#z640_8">set_accel_path()</a> on their parent, each menu item of this menu, that contains a label describing its purpose, automatically gets an accel path assigned. For example, a menu containing menu items "New" and "Exit", will, after set_accel_path("<Gnumeric-Sheet>/File") has been called, assign its items the accel paths: "<Gnumeric-Sheet>/File/New" and "<Gnumeric-Sheet>/File/Exit". Assigning accel paths to menu items then enables the user to change their accelerators at runtime. More details about accelerator paths and their default setups can be found at <a class="el" href="classGFC_1_1Gtk_1_1AccelMap.html#e4">Gtk::AccelMap::add_entry()</a>. <dl compact><dt><b>Parameters:</b></dt><dd>
