[news.eclipse.platform.swt] Re: UI controls friendly with the workspace

["Andrei Serea" <andrei.serea@xxxxxx>]

Ok ok...I have such a class for the Parameter Object which I am actually 
using right now, but my point is: since the eclipse code is a reference 
point for writing eclipse plugins and knowing that the New Java Project 
wizard uses those smart controls i'm talking about, i am just tempted to do 
the same. Anywayz, since nobody knows of the existance of such an api, i'll 
surely stick to my current solution.

Thanks,
Andrei.
