Drawing a circle as overlay on the map

Hey, I was searching for a solution to my problem and found this thread but it seems to be outdated:




My Problem is that I want to draw a circle around the device location (like a radar) but I can't get it done in a satisfying way. First I tried to add an ImageView containing a image of a circle with transparent background but the scaling was not

perfectly done when you zoomed in or out. Another solution was to draw the circle as an QImage but I could not transform the drawn QImage into the necessary ImageView (my solution was based on the scratchpad sample code: https://github.com/blackberry/Cascades-Samples/tree/master/scratchpad).


As far as I understood overlays are not support yet. So maybe someone else found a solution that scales perfectly when the user is zooming in and out and can be done as an overlay on the map. Maybe something in C++ ;-)


Any hints or code snippets are welcome!
