    \brief A component that shows the progress of an event

    A ProgressBar shows the linear progress of an event as its \l value.
    The range is specified using the \l {minimum} and the \l{maximum} values.

    The ProgressBar component is part of the \l {UI Components} module.

    This documentation is part of the \l{componentset}{UIComponents} example.
