I guess I could call it until there is no previous... What I really have is a collection of widgets (two or more) that are linked via the setTabOrder function. When I get to the last widget, I would like to link that widget back to the first widget in the chain to have the last tab go back to the beginning. By the time I get to the last widget, I no longer know the first widget in the chain. I was hoping to find a function where I could index the chain or get the first widget in the chain easily without having to keep calling previousInFocusChain over and over until there is no previous. I was unaware of the functions you gave me, so I will probably, for now, write a function that gets the first by calling previousInFocusChain until no more. Can you tell me if these functions are strictly used for the tab order? Or do the functions include Qt's default tab order? What I mean is, if I call previousInFocusChain recursively until it returns 0, will that widget be the first widget in my tab order?

Thanks,
Eric
