Are you asking how it can work currently, or how it would work with a
new size negotiation scheme? The answer to the first question is that
except for widget specific hacks, gtk+ doesn't provide a way to make
it work.

Answering the second question is a job for whoever gets to design the
extended size negotiation scheme. What I might imagine is that widgets
could report (a) a minimum size ("if you allocate me smaller than
this, you might as well unmap me"), (b) a preferred size ("I provide
full functionality at this size"), and (c) a maximum size ("I can't do
anything useful with any extra space beyond this").

But it is not something I have thought about in great detail.
