QDialog is meant for inheritance (it contains other virtual
functions) ...
The main reason for this is that we inside the dialog
could have a (datadepened) precondition that should
prevent the dialog from being shown at all - instead we
might just want to show a messagebox.
That is not easy solvable in Qt right now. It is possible
to reimplement setVisible - but calling reject from
setVisible does not work. There seems only to be clumsy
solutions to that problem - unless these functions are
made virtual
Beside it also creates a nice symmetry to done.
