#2084 — Drawing line from one JBu

  To: comp.lang.java.gui
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.

Chanchal

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.

I am not associated with GeoSoft.

See http://mindprod.com/jgloss/pane.html

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.
