Sure, this makes the dialog expand and shrink, but now the user cannot change the size. I am trying to do this with a dialog containing text fields, and then resizing the dialog is a big benefit to the user. On windows using MFC we accepted solutions like this, but QT is supposed to be better. QT3 was better, the extension mechanism solved this problem. Sadly there appears to be no solution in QT4.

I just noticed the old duo of setExtension and showExtension from QT3 does still exist and work in QT4.3.1!

So no problem currently. Lets hope the Trolls provide a scaleable alternative before they remove the extension mechanism.
