When I run it with Kaffe+GTK , it worked good. but when i run it with Kaffe+nano-X, I found it cannot show the scene transparent correctly. That is to say, the upper scene always covered the below ones opaquely, when the upper one should be transparent and we should see the below ones.

Is the problem relate with these classes? or kaffe has not implement the tranparent function with nano-X? 

hello Chavaz,

  The Nano-X AWT backend doesn't handle opaquely scense well, and the
semantics of transparency in AWT is broken to Nano-X backend. If you are
willing to look deeper into the implementation, I might be able to able
to help.
