i don't fully understand this, but i don't think it affects my

why do you think you cannot access the width/height of a widget? what
you can't do very easily is to position stuff precisely, relative to
other widgets. Havoc described a constraint widget that solves some of
these problems for fairly simple cases, but I don't think there is a
general solution.

but more importantly, what you're describing is still just aggregation
based on placement. using an existing widget as a member of another
widget doesn't stop the kind of problems that were described.

*if* you want things to work right with all themes, then you need to
create a new widget. otherwise, it will work most of the time, but not
all.
