How to limiti Dial control value?

[Alper]

Hi
i created a QML page contains a Dial control and a Slider. values of each of them controls the value of another.

    Dial
    {
        id: dialC
        value: slider.value
    }
...
    Slider {
        value: dialC.value
        id:sliderC
        orientation: Qt.Vertical
}

i have this problem: when i rotate the dial control, after that it reaches to max value, it goes to 0.0 value (because it can rotate unlimited rounds!), slider goes to min value too.
how i can limit max rounds of dial control to 1 round?
i mean dial only rotates one rounds and stays in max/min.
i want it rotates only one round. (for example only values between 0.0 and 1.0)

thanks in advance
