Arun,

This seems like a plausible solution.  Please don't forget to add
undo/redo capability to your list of steps.  The current method is to
save all of the wires, buses, and junctions on the undo stack.  The
reason for this is there is a clean up algorithm that can change the
line segments so this is the only way to ensure you don't attempt to
undo/redo something that doesn't exist any more.

Cheers,

Wayne
