I'm sorry but that is just wrong. You position the widgets roughly, select
them, then click on the button corresponding to the layout you want to
apply. By selecting a sub-set of the widgets you can create a sub-layout
which itself can be part of a parent layout. You therefore create any sort
of layout you want without specifying a single pixel position or size.
