          \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.
