    \brief Provides a vertical or horizontal slider control.
51
52 
    The slider is the classic control for providing a bounded value. It lets
53 
    the user move a slider handle along a horizontal or vertical groove
54 
    and translates the handle's position into a value within the legal range.
55
56 
    \code
57 
    Slider {
58 
        onValueChanged: print(value)
59 
    }
60 
    \endcode
61
62 
    The Slider value is by default in the range [0, 1]. If integer values are
63 
    needed, you can set the \l stepSize.
64
65 
    You can create a custom appearance for a Slider by
66 
    assigning a \l SliderStyle.
