I already looked a little bit into this problem. Accessor methods are generated
from the attributes and get the scope of the attribute. So if you have a public
attribute, you will also get a public accessor method. Nevertheless, I didn't
found a way how to fix this yet.

The problem still exists in version 1.4.0-beta1. (compiled from source tarball
from 2005-01-15 05:07).
With this behaviour accessor methods are completely useless.
Please try to fix it.

There is also a problem if you don't want accessor method, it is not possible.
If you select it in the umbrello configuration menu it takes no effect. 
So please try to fix the accesor bug.

This bug is still present in 1.5.4. A similar bug in Java code generator has
been fixed according to #59049 more than 3 years ago. Can we have this C++ code
generation bug fixed also?

The bug fixing is so slow because there aren't enough contributors.
I've said this many times: Please everybody consider contributing!
