# override_default.py -- Example of overriding a default value for
#                        a trait attribute in a subclass

#--[Imports]--------------------------------------------------------------------

from traits.api \
    import HasTraits, Range, Str

#--[Code]-----------------------------------------------------------------------

# Example of overriding a default value for a trait in a subclass:

# Define the base class:
class Employee ( HasTraits ):

    name         = Str
    salary_grade = Range( value = 1, low = 1, high = 10 )

# Define a subclass:
class Manager ( Employee ):

    # Override the default value for the inherited 'salary_grade' trait:
    salary_grade = 5

#--[Example*]-------------------------------------------------------------------

# Create an employee and display its initial contents:
joe = Employee( name = 'Joe' )
joe.print_traits()

# Now do the same thing for a manager object:
mike = Manager( name = 'Mike' )
mike.print_traits()
