I started to modify a working demo. I added a 2D grid of buttons. The left column has the property "pos relative to parent" as rpLeft, the middle column to rgCenterHorizontal and the right hand column to rpRight.
When I run it, each column is superimposed at the top and there is no vertical separation of the buttons. The top most button is active, If I just design a layout with no anchoring, every visual object appears at the top left.
So the visual layout bears no relation to what actually happens.
How can I achieve my aim here ?
