<p>Radio buttons are <a href="qml-qtquick-controls2-abstractbutton.html#autoExclusive-prop">auto-exclusive</a> by default. Only one button can be checked at any time amongst radio buttons that belong to the same parent item; checking another button automatically unchecks the previously checked one.</p>
