I am about to go nutz on this....
Before I whinge about the implementation of Python in XSI,
maybe someone can tell me I am doing something stupid so I can fix this
issue once and for all.
OK, I am modularising my code into python modules and recently
discovered that you can do the following from
a module to import the normal Application and XSIFactory etc. objects
for use within that module :
/import win32com
ap = win32com.client.Dispatch( 'XSI.Application' ).Application
XSIFactory = win32com.client.Dispatch( 'XSI.Factory' )
XSIMath = win32com.client.Dispatch( 'XSI.Math' )
from win32com.client import constants as c
/
which is my typical set of imports at the start of all of my modules.
(my previous solution, which worked flawlessly but is the most stupid
way EVER to have to do it, was passing in the Application
object from the base script (as Application is defined and bound within
it by default) and then pass it on to every other module
explicitly, which is only possible in Python via it's lack of
type-checking until run-time. However this is entirely different to the way
that every other supported scripting language within XSI does things, as
with them it is a lot easier to get hold of the Application object. )
The stupid thing is now, despite this is the ONLY thing I have changed
in my code from before where Application
was passed in explicitly, EVERY statement where I do an
object.Properties( "#some_property" ) call fails with
the following error:
for instance trying to get to the viewvis attribute:
/File
"/usr/Softimage/XSI_4.2/Application/bin/win32com/client/__init__.py",
line 454, in __getattr__
# raise AttributeError, "'%s' object has no attribute '%s'" %
(repr(self), attr)
#AttributeError: '<win32com.gen_py.Softimage|XSI Object Model Library
v1.5.Property instance at 0x1669476908>' object has no attribute 'viewvis'
# - [line 453]
#ERROR : OLE error 0x80020101/
Wrapping up the Properties call like this ap.GetValue(
object.Properties( "#some_property" ) ) helps in some situation, but
even then there are a lot of
cases where it still fails. Since the ONLY thing I changed in my code
is the way I am importing Application, things like this should not stop
working.
If I've done something obviously wrong could people please let me know,
or is there something else I am missing.
Sorry bout the longwindedness but I'm trying to be as clear as possible
here.
cheers,
Luke
