\title{Get all active top level loon plots.}
\usage{
l_loonWidgets(pathTypes, inspector = FALSE)
}
\arguments{
\item{pathTypes}{an optional argument identifying the collection of path types that
are to be returned (if displayed).}

\item{inspector}{whether to return the loon inspector widget or not

This must be a subset of the union of
\code{\link{l_basePaths}()} and \code{\link{l_compoundPaths}()}.

If it is missing,
all \code{\link{l_basePaths}()} and \code{\link{l_compoundPaths}()} will be returned.}
}
\value{
list whose elements are named by, and contain the values of, the
loon plot widgets.  The list can be nested when loon plots (like \code{\link{l_pairs}})
are compound in that they consist of more than one base loon plot.
}
\description{
Loon's plots are constructed in TCL and identified with
a path string appearing in the window containing the plot.

If the plots were not saved on a variable, this function will
look for all loon plots displayed and return their values in a list whose
elements may then be assigned to R variables.
