Depending if you want a modal dialog or not you should use different 
approaches. I would in any case subclass QDialog and either show it with 
exec() or show(). exec shows it in modal way, show() is non modal. When 
exec returns you can use the object to fetch the information that was 
entered. When show() is used connect to the dialog's accepted signal. 
You should the use pointer to the dialog object to get entered 
information in the slot that receives the accepted signal.

Hope this helps.
