Mon Sep 11 08:31:21 2006 UTC (17 years, 10 months ago) by johnpye
File MIME type: text/x-chdr
File size: 4021 byte(s)
Bumped version to 0.9.5.98.
Added support for 'setSymbolValue' from C++ interface, and allow symbol variables to be edited via the PyGTK GUI.
Added some limited data about structural analysis of beams in johnpye/aiscbeams.a4c.
Updated johnpye/beam4.a4c to use this data.
Added some currency conversions to measure.a4l.
Added some units related to Mechanics of Solids to atoms.a4l.

29 This class has to be called 'Instanc' in C++ to avoid a name clash
30 with C. Maybe coulda done it with namespaces but didn't know how.
31
32 This class is renamed back to 'Instance' by SWIG, so use 'Instance'
33 when you're in Python.
34
35 The Right Way to implement this class would be as a base class
36 with lots of diffent subclasses for the different atom types.
37 Maybe even multiple inheritance.
38
39 But until the underlying C code is ported to C++ or modularised in
40 some other way, it's not going to be worth the effort. We discussed
41 this in the mailing list.
