How can i change the speed of listview scrolling in QML?

问题

I have created a list by using listview in QML. In my case, i want to change the speed of the list scrolling, scrollBar and the highlight to different value. For example,

Here is a list. While i move the highlight to the next element, three types of animation will be happened.

1. scrollBar will scroll to bottom
2. list will scroll to the top
3. highlight will scroll to the next element

As i known, i can change the the highlight by

ListView {
   highlightMoveDuration : 200
}

I found that three types animations will start at the same time and last for the same time.

But in my case, i want to set three animations to stop at different time. For example:

1. ScrollBar: start:0, End:300
2. List: start:0, End:400
3. highlight: start:0, End:200

How can i do that. Also, if they start at the different time, how can i do that?
