|
# This test will ensure that a virtual C++ method from a base class can
|
|
# be overridden in a derived class implemented in Python, and that when
|
|
# the C++ method is called from C++ that the Python override is called.
|
|
# In addition the Python override will pass the call on to the base class
|
|
# implementation and this test will ensure that is successful as well.
|
|
#
|
|
# The AddChild method is a good cantidate for this test because it is
|
|
# easy to induce a call from C++ (just create a child window) and it is
|
|
# easy to test if the calling the base class AddChild works (the length
|
|
# of the GetChildren list will increase.)
