Help with GraphPinScene and adding of Pins

Hi,

I have been able to try some stuff using GraphPinScene and add Pins etc. 
to an IconWidget. My problem is that I need to place the pins (they are 
images) in certain locations on the IconWidget. Anytime I add pins it 
gets placed in the same location. Could someone guide me to the best way 
to place pins in arbitrary locations on a widget? Thanks
