In general, if the PythonCard component doesn't support one of the 
styles supported by the underlying wxPython control, you'll have to 
subclass the PythonCard component or just modify it to suit your 
purposes. PythonCard will look for components in a directory called 
appcomponents in your main application directory before it loads from 
the default component list, so that can be used to override which 
version of a component is used if you want something 
application-specific. If you decide to provide you're own about the 
only thing you need to provide in the subclass is a replacement 
__init__ method, so just copy that from the original and change the 
style.

In the case of this style, it is something that PythonCard really 
should support, so I'll make appropriate modifications to the 
multicolumnlist component and post something here once that is done.
