\brief Exclusive item delegate with a radio indicator that can be toggled on or off.
\image qtquickcontrols-radiodelegate.gif
RadioDelegate presents an item delegate that can be toggled on (checked) or
off (unchecked). Radio delegates are typically used to select one option
from a set of options.
RadioDelegate inherits its API from \l ItemDelegate, which is inherited
from AbstractButton. For instance, you can set \l {AbstractButton::text}{text},
and react to \l {AbstractButton::clicked}{clicks} using the AbstractButton
API. The state of the radio delegate can be set with the
\l {AbstractButton::}{checked} property.
Radio delegates are \l {AbstractButton::autoExclusive}{auto-exclusive}
by default. Only one delegate can be checked at any time amongst radio
delegates that belong to the same parent item; checking another delegate
automatically unchecks the previously checked one. For radio delegates
that do not share a common parent, ButtonGroup can be used to manage
exclusivity.
\l RadioButton is similar to RadioDelegate, except that it is typically
not used in views, but rather when there are only a few options, and often
with the requirement that each button is uniquely identifiable.
\code
ButtonGroup {
id: buttonGroup
}
ListView {
model: ["Option 1", "Option 2", "Option 3"]
delegate: RadioDelegate {
text: modelData
checked: index == 0
ButtonGroup.group: buttonGroup
}
}
\endcode
