\qmltype ToggleSwitch

\brief A component that can be turned on or off.
A toggle switch has two states: an \c on and an \c off state. The \c off
state is when the \l on property is set to \c false.
The ToggleSwitch component is part of the \l {UI Components} module.
This documentation is part of the \l{componentset}{UIComponents} example.
