i wonder if it is possible to add something like a button to a graphics?
i want to plot a tree, where i can expand a node, by clicking on it.
is this possible? or do i have to enter the target nodename all the
time,
i want to expand the tree using something like
ButtonBox[<snip>,ButtonData :> InputString["Node to expand:"]]
not very elegant..

tnx,
