Listing 9.33. Overridden functions in the InputDialog class.

Sometimes an overridden function in the derived class needs to call the existing function

in the base class. e prepareVerts function does just that. e syntax is BaseClass::

function(); and can be seen in Listing 9.34. e inputDialog.cpp le contains the

remaining code, which we will leave for the reader to explore.
