Anchoring the widgets for resizing with the form
-
"niche concept"?
Are you sure layouts are a niche concept?
As far as I know Java GUI for example uses layouts as well (see https://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html). I like layouts - they are very flexible and powerful. -
Adding a layout to the UI elements on a form resizes and rearranges them all and it is not possible to change their sizes once they are in a layout. How's that powerful and flexible?

The layout define the size.Not reversed.
If you dont want the layout size for all widgets ,
u can then adjust with min/max sizes on individual widgets.
You can also instruct layout if u want to be greedy and use all space/and or other options. -

The anchors do not require defining fixed sizes. -

Yeah but layouts dont either.
Its assumed u want same size for all.
So only if u dont , u set it.
Its not double work as often NOT needed.
I want same size for all anyway.
and u can have margins if u want and many other nice tweaks. -

The anchors do not require defining fixed sizes.Neither do layouts. There are things called resize policies and stretch factors, which I suppose you should take a look at. Also how do you anchor two elements back to back such that one of them takes 2/3 of the space and one 1/3, ain't it necessary to go and set that manually?

If the layouts are so wonderful, can anyone explain why specifying a horizontal layout for a form with 3 panels adds 9 pixel margin on all sides of the form? How can that margin be eliminated?

Simple: For centralWidget set layoutLeftMargin, layoutRightMargin, layoutTopMargin, layoutBottomMargin, and layoutSpacing all to 0. Default is 9, resp. 6.

BTW: If you want a fancy GUI that doesn't look / behave natively then you can use QtQuick for that. Besides layouts it has anchors, too.
