Thanks for the idea! I have already implemented this solution with a
snapshot and have been able to track for the location of the controls on
windows under the toplevel. This works just fine but does not take into
account that other applications are updating the content of their windows to
give real-time feedback to user.

Probably the better solution is through externals. That I cannot!

To Ken, polygons allow to have connectors between two points with two
segments at right angles (horizontal and vertical). This is for a pleasant
look. Have a look to the way WebObjects Builder or Interface Builder is
connecting two objects. This is better looking than an oblique line.
