A single radio button performs the same basic function as a <a class="el" href="classGtk_1_1CheckButton.html">Gtk::CheckButton</a>, as its position in the object hierarchy reflects. 
<p>
It is only when multiple radio buttons are grouped together that they become a different user interface component in their own right. Every radio button is a member of some group of radio buttons. When one is selected, all other radio buttons in the same group are deselected. A <a class="el" href="classGtk_1_1RadioButton.html">Gtk::RadioButton</a> gives the user a choice from many options. After constructing the first <a class="el" href="classGtk_1_1RadioButton.html">RadioButton</a> in a group, use <a class="el" href="classGtk_1_1RadioButton.html#0591be656af22e98ec374b25175ceead">get_group()</a> and provide this Group to the constructors ot the other RadioButtons in the same group. To remove a <a class="el" href="classGtk_1_1RadioButton.html">Gtk::RadioButton</a> from one group and make it part of a new one, use <a class="el" href="classGtk_1_1RadioButton.html#bd7707f4113d7006c35eee47d4243df5">set_group()</a>.<p>
The <a class="el" href="classGtk_1_1RadioButton.html">RadioButton</a> widget looks like this: <div align="center">
