Sounds interesting - I was going to hack to uic to generate java instead of 
C++. I hadn't thought of doing something clever with stylesheets to do it. It 
would certainly be a big improvement if it was possible to use Qt Designer 
with QtJava.

The virtual method callbacks to the polish() methods are missing, and the uic 
generated code overrides those. That was something I was meaning to fix.

Oops - this is totally wrong - not useful at all! I've changed the uchars to 
map onto java shorts in both the HEAD and KDE_3_1_BRANCH branches of the 
qtjava project.
