Hi.
If you look for ideal elements fit, like in form in QTCreator, You don't have to use Layout.
Just put widgets on place, make it ALL proportional etc.
include class I put below, I put example too at the end
It works like a charm, if you will have to use QLayouts, make them MaxMin constraint, but results may be strange. When you use it, better forget about layouts ;)

EXAMPLE 1:
....
ui->setupUi(this);
geofit geo;
geo.widgetsResizer(this);
showFullScreen();
....
you can use it external. too:
geofit geo;
a=new a(this)
b=new b(this)
c=new c(this)
geo(a);
geo(b);
geo(c);
Good luck :)
