This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Adds a module
module defines a type
RPN for operators, which is an
Data.Monoid.Monoid class. You can combine those
operators using reverse polish notation, as made popular by,
say, HP calculators. There are operators for layout elements,
like expanders, panes, boxes and notebooks, and for a few
other widgets, like buttons and labels. You can also insert
gtk2hs widget in the stack.
