\brief A switch.
A Switch is an option button that can be switched on (checked) or off
(unchecked). Switches are typically used to represent features in an
application that can be enabled or disabled without affecting others.
On mobile platforms, switches are commonly used to enable or disable
features.
\qml
Column {
Switch { checked: true }
Switch { checked: false }
}
\endqml
You can create a custom appearance for a Switch by
assigning a \l {QtQuick.Controls.Styles::SwitchStyle}{SwitchStyle}.
