Steve Wessels has three versions of DesktopBackgroundLoader in the inbox
Version 22 subclasses model thus duplicating FileList functionality
whereas version 26
Bert Freudenberg was saying as a comment to 22 that the Background
Loader duplicates FileList code and as such he prefers going for a
subclass of FileList which Steve did with 26.
As we now find out is that FileList has not good code in it.
Steve's version 22 is cleanly done and a good application of the new
It shows that displaying pictures in a explorer type dialog is indeed possible
(see screen shot on Steve's website
So a solution (either along the lines of version 22 or version 26) is
not out of reach...
We just have to make up our mind how we proceed.
