# since there are no other virtuals that we are exposing here, then all
# classes that derive from wxObject that do not have any virtuals of
# their own (or have the virtual flags turned off by the tweaker code)
# can have simpler wrappers generated for them with no extra derived
# class whose only purpose is to reflect calls to the virtual methods to
# Python implementations. (And since the only virtual is the dtor then
# that is of no real benefit to Python code since we're not overriding
# the dtor anyhow.) In addition it appears so far that none of these
# classes would ever need to have Python derived classes anyway. This
# also makes it easier and less SIP-specific to add or replace ctors in
# those classes with custom C++ code. (See wxFont and wxAcceleratorTable
