    brief: The example shows how to combine QLabel and QScrollArea to
    display an image.

    QLabel is typically used for displaying text,
    but it can also display an image. QScrollArea provides a
    scrolling view around another widget. If the child widget exceeds
    the size of the frame, QScrollArea automatically provides scroll
    bars.
