it's funny how you correctly describe the situation for splitters and
completely fail to see the analogy here, despite it being even more
blatant: the name i proposed is linkDimension. the target object is
rather clear, and the width dimension is unarguably horizontal, i'd
think. but you are still thinking of the stacked widgets ...

a workable solution would be adding a new
enum Dimension { Width, Height }.
conveniently, this would also apply to the splitter case.

the QLayout base api doesn't have a concept of rows and columns.
