I have a project in which I need to construct an interface, composed

all be
different sizes. I need to lay those out on a single screen. I want
it to be
fairly predictable, so removing one widget doesn't completely
rearrange the
entire interface.
I have been thinking about this problem for a while, and still have
nothing
to show for it. I am not even sure where to start. I would imagine
this is a
common problem, and has been tackled many times before me (for
example,
Expose lays out all of the windows very nicely). Do you have any
advice on
where to look, or a neat algorithm to use?
It's a bit hard to visualise what you're really after, from your
description.
Automatic layout can be done in lots of different ways, but its hard
to advise on where to look for more info without having a better idea
of what you want.
I believe the algorithm used by Exposé is patented by the way, so you
probably couldn't use it if you wanted to (unless Apple "expose" the
algorithm in a official API, which currently isn't the case).
Googling for "rectangle tiling algorithm" might help you.
