AFAIK the meanings of the sizehint and the minimumsize are not similar.
I will check if it is possible to use the minimum rectangle of the sizehint
and the minimum size.
But the dialogbase sets its own minimum size to a value calculated from
the main widgets minimum size. What if both are different?
Any ideas? Trolls?

I will check it. Same is for dialogbase.
