Implementation of an InstanceEditor demo plugin for the Traits UI demo program.

capabilities.

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

# 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):
