This sounds to me like you are trying to force Qt to do something that 
some other system used to do?

I have a lot of requests from customers and I always try to make them 
accept that the default way of doing things are there for a number of 
reasons and they should accept it the it is. So, my advice is to stop 
thinking about this. Or make the guy deciding this stop thinking about it :)

However, if you can't do that, you always have options. Here are a set 
of some of the things I would try:

- Set the maximum height on the QMenu

- Work with the width for height tricks

- You can move the menu after it appears with either a reimplementation 
in the resizeEvent, eventFilter on resize or other events, or using 0 
time single shot timer

- There are probably a bunch of possible hacks that might work in the 
area of proxy QStyle subclasses

I hope this helps.
