##' A main window (gwindow) can be "decorated" with
##' * a toolbar. This shows in the window at the top or below the menu. In tcltk, the style
##'   option is not heeded
##' * a menubar. This shows at the top of the window in most cases, but may appear in the
##'   system menubar (Qt and Mac, Aqua tcltk, ..)
##' * a statusbar. This shows at the bottom of the page, usually set off by appearing in a gutter,
##'   though this is style dependent
##' * an infobar. In RGtk2 this is an actual widget that shows transient messages below the toolbar.
##'   The other toolkits may have something similar hacked in. The infobar -- if present -- is called
##'   by gaction when the parent is a main window.
