State_preMixin.py - help classes define change-tracked attributes using the State macro

History:
080910 bruce split this out of test_connectWithState.py, since it's
been used in real code for some time
"""
from exprs.ExprsMeta import ExprsMeta

# TODO: refile (alongside IorE_guest_mixin ? in its own file?), once cleaned up & bugfixed --
# note, as of 080128 or so, this is used in real code.
"""
Use this as the *first* superclass (thus the _preMixin in the name)
in order to permit use of the State macro in the class assignments
which set up instance variable defaults in a given class.
The glpane (*not* the commandSequencer!) must be passed as the
first argument to __init__.
"""

# along with the IorE_guest_mixin superclass; this may be cleaned up:
__metaclass__ = ExprsMeta

_e_has_args = True # not needed -- only purpose is to remove "w/o a" from repr(self)

# infinite recursion, but something prevents it from happening at all
# (it seems likely that no call at all is happening, but this is not yet
# fully tested -- maybe something different is called from what's printed)
