<hr><a name="_details"></a><h2>Detailed Description</h2>
A GtkRadioMenuItem C++ wrapper class.
<p>
A radio menu item is a check menu item that belongs to a group. At each instant exactly one of the radio menu items from a group is selected. You create a group radio menu items the same way you would create a group of buttons (see <a class="el" href="classGFC_1_1Gtk_1_1RadioButton.html">Gtk::RadioButton</a>).<p>
Radio menu items are constructed with one of the following constructors:<p>
<div class="fragment"><pre> <a class="code" href="classGFC_1_1Gtk_1_1RadioMenuItem.html#z725_0">RadioMenuItem</a>(<span class="keyword">const</span> RadioMenuItem *group, <span class="keyword">const</span> <span class="keywordtype">char</span> *label, <span class="keywordtype">bool</span> use_underline = <span class="keyword">false</span>);
<a class="code" href="classGFC_1_1Gtk_1_1RadioMenuItem.html#z725_0">RadioMenuItem</a>(<span class="keyword">const</span> RadioMenuItem *group, <span class="keyword">const</span> String& label, <span class="keywordtype">bool</span> use_underline = <span class="keyword">false</span>);
</pre></div><p>
The group argument is a pointer to an existing <a class="el" href="classGFC_1_1Gtk_1_1RadioMenuItem.html">RadioMenuItem</a> that already has a group assigned to it. The first radio menu item in a group is constructed by passing null as the group argument. Then subsequent menu items are constructed by passing an existing menu item as the group argument, usually the last one constructed.<p>
<div class="fragment"><pre> Gtk::RadioMenuItem *menu_item = 0;
menu_item = <span class="keyword">new</span> Gtk::RadioMenuItem(menu_item, <span class="stringliteral">"Item1"</span>);
menu->append(*menu_item, item1_slot);
menu_item->show();
menu_item = <span class="keyword">new</span> Gtk::RadioMenuItem(menu_item, <span class="stringliteral">"Item2"</span>);
menu->append(*menu_item, item2_slot);
menu_item->show();
menu_item = <span class="keyword">new</span> Gtk::RadioMenuItem(menu_item, <span class="stringliteral">"Item3"</span>);
menu->append(*menu_item, item3_slot);
menu_item->show();
</pre></div><p>
To remove a <a class="el" href="classGFC_1_1Gtk_1_1RadioMenuItem.html">RadioMenuItem</a> from one group and make it part of a new one, use <a class="el" href="classGFC_1_1Gtk_1_1RadioMenuItem.html#z727_0">set_group()</a>.

Connect to the group_changed_signal; emitted when the group of radio menu items that a radio menu item belongs to changes.
<p>
This can be when a radio menu item switches from being alone to being part of a group of 2 or more menu items, or vice-versa, and when a button is moved from one group of 2 or more menu items to a different one, but not when the composition of the group that a menu item belongs to changes. </td>
