[Interest] Designer - grid layout

[Phil]

Thank you for reading this.

I'm trying to create a 3 x 3 grid of edit boxes and it seems that 
Designer will only allow me to create either a horizontal line or a 
vertical line of boxes.

I was expecting to to able to set grid layout's property to 3 x 3 but 
that doesn't seem possible. The Qt manual includes an example of a grid 
layout but not how to have Designer create a 3 x 3 grid of widgets, for 
example.

A Google search didn't turn up anything helpful.
