##' constructor for a two-paned container
##'
##' A container for holding two child widgets where the space
##' allocated to each can be manipulated by the user with a pane
##' between the widgets, or programatticaly via \code{svalue<-}. The
##' value specified to \code{svalue<-} can be a number in $[0,1]$, in
##' which case it is a proportion or an integer, in which case it is a
##' pixel size (from the left or the top). The ambiguous case \code{1}
##' or \code{1L} is determined by class. The value of \code{svalue} is in proportion units.
##'
##' Child widgets are added in the usual way, typically through the
##' \code{container} argument of a constructor. Only two children may
##' be added. Children expand and fill the allocated space.
##' @param horizontal direction of layout
##' @inheritParams gwidget
##' @export
##' @note Setting the size is often only possible after the container
##' has been realized on the screen. In the example, this call of
##' \code{svalue<-} is done after the parent window is made visible
##' for this reason. There were arguments to specify the children at
##' construction, but these have been removed.

##' w <- gwindow("gpanedgroup", visible=FALSE)
##' pg <- gpanedgroup(cont=w)
##' gbutton("left", cont=pg)
##' gbutton("right", cont=pg)
##'
##' visible(w) <- TRUE
##' svalue(pg) <- 0.33
