Hello All,

I'm developing some thing like an electronic circuit designer. I have
a number of JButtons placed programatically on a JPanel. Now I need to
draw lines between pairs of JButtons by dragging mouse from one button
to another one. Please advice on how such a thing can be implemented.
Also i should be able to delete such lines drawn. KIndly advice
Thanks in advance.

GeoSoft graciously provides a free, small, and in my opinion, very nice
graphics library that may do exactly what you want. If nothing else you
could study their source code.

The trick might be to draw the lines on a different pane. You let the
layout manager place the buttons, then you ask the buttons where they
are with getLocation.
