[news.eclipse.platform.swt] Re: No common IList interface for List and C

Hi,

Well you can subclass you "only" have to overwrite checksubclass method 
or something like this. The reason for swt to say you should not 
subclass is that it's harder to keep an API-contract with classes who 
are subclassed. Not making them final still gives the developers a 
chance to subclass although it's NOT how you are expected to use them.
