Can someone help me figure out how to use EventHandler
to evaluate an expression when one of many Disk[]
objects in a Graphics Pane is clicked.
For example suppose I create a red and green disk in a
graphic:
Graphics[{Red, Disk[{1, 1}, 0.5], Green, Disk[{2, 2},
0.5]}]
Each disk is a separate and editable object in the
graphics pane. Can I therefore associate an Event with
a Mouseclick on each disk? To make matters simple lets
say the disk change color from Red to Yellow and Green
to Brown.
