Hi Nick, 

I use a QWizard dialog built in the designer, so no wizard page overrides.  I use nextId to setup each page, validateCurrentPage to do validation of fields, and a currentIdChanged slot to do the actual work depending on the page transition.  I used an in-progress page while accessing the network.  

It was extremely painful and frustrating to use.  The history and cleanup mechanism kept getting in the way.  It's a shame there is nothing simpler that just displays the pages in the correct system layout and images, without the extra crap!  

Good luck! 

Tony.
