DrGeoII, dynamic geometry for Squeak, released under LGPL

I am please to announce the distribution of DrGeoII, an interactive
geometry framework for Squeak, under the LGPL

http://www.squeaksource.com/DrGeoII.html

DrGeoII is roughly based on previous DrGeo (http://www.ofset.org/drgeo)


It is far to be finished, but it is already in a quite well polished and
usable state.

Very nice!

The only problem I found was the non working property editor. But maybe I did
something wrong.

Would you think it feasible to develop DrGeo into a parametric (aka constrain
based) sketcher? Its used in about every MCAD software but I have never seen
an open source implementation.

Cheers, Torsten

A couple of features are not yet implemented

Really I am not sure.

How to run DrGeoII?
I'm using Squeak 3.9

Has it been tested with 3.9?

I experienced the same problem, but was able to run
DrGeoII in a fresh Squeak 3.8.
Seemingly in Squeak 3.9 two icons for the menu bar
got lost   (MenuIcons>>undoIcon, MenuIcons>>redoIcon)


Hope this helps
Boris

Yes, it will not work with 3.9. It need tiny modification, it is because
the way to access Squeak icons has a bit changed between 3.8 and 3.8.

For now you can use it with 3.8

I just could open a DrGWindow but when i click on an image i get an
error on mouse release.

Ok, i think' i'll wait until it works on a 3.9 image.
Good work.
