<h2 class="description">Description</h2>
<p>
Menu radio item. Similar to <a class="normal" href="CastleWindow.TMenuItemChecked.html">TMenuItemChecked</a>, but it belongs to a group and within this group only one (or none) radio button can be checked.
<p>Note that <a class="normal" href="CastleWindow.TMenuItemChecked.html#AutoCheckedToggle">AutoCheckedToggle</a> property has a little different meaning in this class: whenever user will click on some item, it will be automatically set to Checked = <code>True</code> and the rest of items within this group will be set to Checked = <code>False</code>.
<p>You can of course operate on Checked property explicitly, setting it to <code>True</code> or <code>False</code>.</p>
