54
55 RadioButton presents an option button that can be toggled on (checked) or
56 off (unchecked). Radio buttons are typically used to select one option
57 from a set of options.
58
59 RadioButton inherits its API from \l AbstractButton. For instance,
60 you can set \l {AbstractButton::text}{text} and react to
61 \l {AbstractButton::clicked}{clicks} using the AbstractButton API.
62 The state of the radio button can be set with the
63 \l {AbstractButton::}{checked} property.
64
65 Radio buttons are \l {AbstractButton::autoExclusive}{auto-exclusive}
66 by default. Only one button can be checked at any time amongst radio
67 buttons that belong to the same parent item; checking another button
68 automatically unchecks the previously checked one. For radio buttons
69 that do not share a common parent, ButtonGroup can be used to manage
70 exclusivity.
71
72 \l RadioDelegate is similar to RadioButton, except that it is typically
73 used in views.
