How to use PathAttribute as Rotation angle?

yongsungkim

I write a code as following in PathView.qml. But 'rotation' as pathattribute is not applied.
I tried to search a solution for this problem. But the solution can not be found.

error :
file:///C:/Users/yongsung85.kim/Desktop/Workspace/PathView/PathView.qml:73: Unable to assign [undefined] to double

Why not available onlay pathattribute 'rotation' in transform Rotation?

Use this:

    transform: Rotation {
        origin.x :width/2
        origin.y :height/2
        axis {
            x: 0
            y: 1
            z: 0
        }
        angle: appDelegate.PathView.rotation   <<-----
    }
