That is, they +can be switched on (checked) or off (unchecked). The classes +differ in how the choices for the user are restricted. Check boxes +define "many of many" choices, whereas radio buttons provide a +"one of many" choice. In a group of radio buttons only one radio +button at a time can be checked; if the user selects another +button, the previously selected button is switched off. +<p> The easiest way to implement a "one of many" choice is simply to +put the radio buttons into <a href="qbuttongroup.html">QButtonGroup</a>. +<p> Whenever a button is switched on or off it emits the signal +<a href="qbutton.html#toggled">toggled</a>(). Connect to this signal if you want to trigger an action +each time the button changes state. Otherwise, use <a href="#isChecked">isChecked</a>() to +see if a particular button is selected. +<p> Just like <a href="qpushbutton.html">QPushButton</a>, a radio button can display text or a +pixmap.
