Thanks for reply wysota !

Im sorry to ask, but is there any example somewhere ? I am a noob.
I searched on the net and even here but all I could find were widgets with properties that were int or string.

As I understand it it must be something like :

registerField("name", myWidget, "myProperty", SIGNAL(selectionChanged()));

so i conclude that i must declare my own widget and my own propery. Is this correct ?
My purpose is to make variables like a QList accessible to any/all wizardPage subclass.
