QML ScrollViewStyle width?

问题

I'd like to make a ScrollView's scroll bar wider than the default value, but I don't see any width properties, even as part of the ScrollViewStyle element's frame component.

To make the scroll bar wider, you can change the following four properties in ScrollViewStyle with your custom components: handle, scrollBarBackground, decrementControl, and incrementControl (it may look weird if you do not change all of them). For example,

ScrollView {
    style: ScrollViewStyle {
        handle: Rectangle {
            implicitWidth: 50
            implicitHeight: 30
            color: "red"
        }
        scrollBarBackground: Rectangle {
            implicitWidth: 50
            implicitHeight: 30
            color: "black"
        }
        decrementControl: Rectangle {
            implicitWidth: 50
            implicitHeight: 30
            color: "green"
        }
        incrementControl: Rectangle {
            implicitWidth: 50
            implicitHeight: 30
            color: "blue"
        }
    }
    //...
}

and it looks like this:
