Re: [platform-swt-dev] Access to COM

[jml <jml@xxxxxxxx>]

I understand that.
Just as people love the COM support architecture build in swt (thanks 
for the excellent work), why not make it a full COM layer?

In fact, what I need is less than a full layer, I just need more 
VtblCall() methods, I think with that, I can almost do everything I need 
for COM/OLE.
