This is the current package behavior. Another interesting use case, you can
bring, is based classes. You will not see the variables from the base
classes.
Take a look on this document:
http://pygccxml.svn.sourceforge.net/viewvc/pygccxml/pygccxml_dev/docs/query_interface.rest?revision=1727&view=markup
and
then on pygccxml/declarations/scopedef.py - variables method.
In your case, it is very simple to get the desired variables:
class_vars = classType.variables( lambda var: var.parent is classType )
