Implementation of an InstanceEditor demo plugin for the Traits UI demo program.
This demo shows each of the four styles of the InstanceEditor

capabilities.

#-------------------------------------------------------------------------
# Classes:

# The actual attributes don't matter here; we just need an assortment

# The InstanceEditor uses whatever view is defined for the class. The
# default view lists the fields alphabetically, so it's best to define one
# explicitly:
view = View('name', 'occupation', 'age', 'registered_voter')

"""
# Create an Instance trait to view:
sample_instance = Instance(SampleClass, ())
# Items are used to define the demo display, one item per editor style:
inst_group = Group(
Item('sample_instance', style='simple', label='Simple'),
Item('_'),
Item('sample_instance', style='custom', label='Custom'),
Item('_'),
Item('sample_instance', style='text', label='Text'),
Item('_'),
Item('sample_instance', style='readonly', label='ReadOnly')
)
# Demo View:
view = View(
inst_group,
title='InstanceEditor',
buttons=['OK'],
resizable=True
)
# Create the demo:
demo = InstanceEditorDemo()
# Run the demo (if invoked from the command line):
