For mouse-click stuff, you want ActionNotify() in action.c. That's

Agreed!

I forgot it: as you are just interested in simulation, there's another

more accurate and "proffesional" than Ktechlab, although it is more
difficult to learn (and let me say it's uglier too ;-) ). And I think

Hi,
I'm an electrical engineering student and I'm new to gEDA. I'm given a
project and I've got several circuits. I want to simulate rather than
soldering them all actually so that I can choose the best circuit. I
use Fedora 12 and I have installed ng-spice also.
My circuit has a NE555 timer and

I'm not sure what this comment relates to, or whether it is intended to
be constructive, humorous or otherwise.. Nothing I've seen suggests the
