This only works if all the GUI elements are of fixed size.
If you are writing a MUA, for example, there are several elements which
are essentially of arbitrary size: A list or tree of mailboxes. A list
(or forest) of mails in the current mailbox. A pane to display the
current mail. To size these properly you have to know what kind of
information is going to be displayed. Depending on the screen size it
may be better to only show one of them at a time. The application
programmer knows this. The layout system doesn't. This should also be
configurable by the user, which again means that the application has to
a) provide a configuration UI and b) has to be able to set the layout
the way the user configured it.
Layout systems are important and useful. But they are tools, they can't
do everything by themselves. In the end the application programmer has
to decide how to use them.
