Well, Espen Sand knows, he is the one who changed KDialogBase to its
current state. He also introduced the weird KJanusWidget, which in my
opinion is a violation of the C++ approach (it displays the different
kinds of dialogs, but this should be done in a couple of derived widgets).

But I think the respective dialog developer will have to decide which
widget should have focus first.
