Re: Overlap bitmapfield, bitmap or images

I don't think there is any way to do it using existing BB fields.  You'll have to override paint(Graphics) and do it manually.  Take a look at Graphics.drawLine() (for hands) and Graphics.drawArc() (for the clock's face).  Redrawing each time is fine so don't hesitate to clear the Field (Graphics.clear()) and redraw everything again.

 

Good luck!
