In above-mentioned steps, in order to realize the interaction of scroll bar and mouse, need to control to the Rectangle that id is button
Part increases a child control MouseArea, and code is as follows:
MouseArea{
drag.target:button
drag.axis:Drag.YAxis
drag.minimumY:spacing_
drag.maximumY:nobleScrollBar.height-button.height-spacing_
anchors.fill:button
cursorShape:Qt.PointingHandCursor
}
Be arranged MouseArea drag target be button, drag coordinates axis be Y-axis, dragging range be [spacing_,
NobleScrollBar.height-button.height-spacing_], when mouse is suspended on scroll bar, mouse-shaped

Delta=target_.contentY+headerHeight_
Multiple=nobleScrollBar.height-button.height -2 × spacing_
Distance=target_.contentHeight-target_.height
Button.y=delta × multiple/distance+spacing_
It should be noted that in QML, Flickable there are two child control type, grid view (GridView) and
List View (ListView), the two controls have header and footer attribute, if your Flickable is
GridView or ListView, and the two attributes are provided with, they will affect the value range of contentY, it is assumed that
A height of footerHeight of a height of headerHeight of header, footer, then the value range of contentY just becomes
Are as follows:
[- headerHeight, contentHeight+headerHeight+footerHeight-height], and need
It is come into headerHeight and footerHeight as attribute in nobleScrollBar, when calculating Flickable's
When contentY, following formula is used:
Delta=button.y-spacing_
Distance=nobleScrollBar.height-button.height-2 × spacing_
Multiple=headerHeight_+target_.contentHeight+footerHeigh t_-target_
.height
Target_.contentY=delta × multiple/distance-headerHeight_
When calculating the y value of button, need using following formula:
Delta=target_.contentY+headerHeight_
Multiple=nobleScrollBar.height-button.height-2*spacing_
Distance=headerHeight_+target_.contentHeight+footerHeigh t_-target_
.height
Button.y=delta*multiple/distance+spacing_
