Ok, great, that is the most specific description of what qobject_cast is 
supposed to be I have read. That is much clearer than the documentation, 
which says:

"""
The qobject_cast() function behaves similarly to the standard C++ 
dynamic_cast()
"""

Note that it does not say "exactly" it says "similarly" -- it is vague, very 
vague. When Qt docs say something vague like that I have _no_idea_ what to 
expect. Perhaps the writer meant "the same as" but that's not what's 
written.

I have filed the bug.

Thanks.

Ross.
