I'm not sure java programmers would want to customise behaviour by writing
java embedded in xml though - it sounds a bit ugly to me.
The idea of the .ui.h file was to allow C++ methods to be added to a class
generated from a .ui file. If there were init() or destroy() methods added in
the .ui.h, then calls to them are included in the constructor/destructor of
the generated class.
So the equivalent in Java would be to have a <some name>.ui.java file
containing additional java methods. When the java class was being generated
from the .ui file, instead of a include directive for the .ui.h file, it
would merge to java methods from the .ui.java into the generated class. I
would have thought XSLT could do that ok - it doesn't sound complicated to
me.
If a method called init() had been added to the .ui.java file then the
constructor would call it. Java doesn't have destructors, so destroy()
doesn't seem to fit in.

Well not really my code (thankyou Trolltech!), I mostly just changed 'Cpp' to
'Java' everywhere.
A couple of the dialogs in the javaeditor are .ui files, so they can be
changed quite easily to be more java-like if needed - we don't need 4
different build systems for 4 platforms - maybe just generate a suitable ant
build file for the project, or automake for gcj.
