Updating duration in Animation.Infinite loop using a slider

[jruxton]

Hi I have a SequentialAnimation containing a number of ColorAnimations in an infinite loop. I want to update the duration properties in the ColorAnimations with a slider.

ie. duration : sliderHorizontal1.value

This works only after I restart the animation. I want the animation to change speeds while it is running as I move the slider. Is this possible? A snippet of my current code is below.

Thanks

@Slider {
id: sliderHorizontal1
x: 55
y: 425
minimumValue: 100
value: 100
maximumValue: 2000
onValueChanged: text1.text=Math.round(value);
}

SequentialAnimation {
    loops:Animation.Infinite
    id: playbanner
    ColorAnimation {
        id:cA1
        target: rect1
        property: "color"
        from: "black"
        to: "white"
       duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect1
        property: "color"
        from: "white"
        to: "black"
        duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect2
        property: "color"
        from: "black"
        to: "white"
        duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect2
        property: "color"
        from: "white"
        to: "black"
        duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect3
        property: "color"
        from: "black"
        to: "white"
        duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect3
        property: "color"
        from: "white"
        to: "black"
        duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect4
        property: "color"
        from: "black"
        to: "white"
        duration: sliderHorizontal1.value
    }
    ColorAnimation {
        target: rect4
        property: "color"
        from: "white"
        to: "black"
        duration: sliderHorizontal1.value
    }
}
function mouseFunction(){
    if(!playbanner.running)
    playbanner.start()
    else if(playbanner.running)
    playbanner.stop()
}@

The only way I have found a way around this is to stop and start the animation in a slider onValueChanged function, Unfortunately this also resets the animation to the beginning which I would prefer not to do. I'm new to Qt Quick. I'm sure there is a better way. Any help would be appreciated.
Thanks
