Thank you Ellen for your helpful reply. I understand how to create and 
connect to a member dialog but I thought a dialog as a separate class was 
the preferred method? Maybe not in this instance?

John's reply, has me intrigued and may lead to an answer to a long standing 
difficulty.

Take this code for instance:

connect(action_OpenMyDialog, SIGNAL(triggered()), this, 
SLOT(showDialog()));

This works if showDialog() is a member of the class that sends the signal 
but how do I write code where the showDialog() slot is a member of a 
different class?
