Catch only ImportError where sufficient #163

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
In sfepy/postprocess/viewer.py, it should be:

try:
    from enthought.traits.api \
         import HasTraits, Instance, Button, Int, Bool, on_trait_change
    ...
except ImportError:
    ...

Alternatively, add some further exception classes.  But currently, all 
exceptions are caught.  This can lead to misguiding tracebacks.  In my case, no 
X terminal was found, yet the interpreter reported an import error (with one of 
the modules after the "except").

It must be "no X server" of cause.

This try: clause is a workaround for incompatibility between mayavi 4.0.0 and 
3.x.x. I have 4.0.0. and catching just ImportError works for me, so it's in. 
Thanks!
