public class StickyHandleLayerExample
This example shows another way to create sticky handles. These handles are not added as children to the object that they manipulate. Instead they are added to the camera the views that objects. This means that they will not be affected by the cameras view transform, and so will stay the same size when the view is zoomed. They will also be drawn on top of all other objects, even if those objects overlap the object that they manipulate. For this setup we need to add and updateHandles activity that makes sure to relocate the handle after any change. Another way to do this would be to add change listeners to the camera and the node that they manipulate and only update them then. But this method is easier and should be plenty efficient for normal use.
