When are you calling it? I vaguely remember some dance widgets go through with their layouts (and parent layouts) before some values have any meaning. But I have not had to muck with this stuff in ages. I would assume that implementing your own QLayout class and implementing/overriding the appropriate methods would be sufficient to avoid having to know the dance moves. You may have to look at the source to, say, QHBoxLayout and see what it is doing and mirror it except in the place where you report to others your preferred and minimum horizontal size.
