I have added a script to the examples folder that has all the option.append types I know of. I will add to it as a ready reference as I become aware of others.
Options.append([None, WindowsInputTypes.Image, 'test.png', 114]) #image file in same directory as script
Options.append(['Choose Axis', WindowsInputTypes.Axis, None])
Options.append(['Choose Edge', WindowsInputTypes.Edge, None])
Options.append(['Choose Face', WindowsInputTypes.Face, None])
Options.append(['Choose Plane', WindowsInputTypes.Plane, None])
Options.append(['Angle 0..360°', WindowsInputTypes.Real, 15.000])
Options.append(['Name of the item', WindowsInputTypes.String, 'Baz'])
Options.append(['Enabled', WindowsInputTypes.Boolean, True])
Options.append(['Count', WindowsInputTypes.Integer, 123456])
Options.append([None, WindowsInputTypes.Label, 'Label Text'])
